While it is now well established that the mechanics of the cellular microenvironment regulate various biological processes\, most studies have focused only on the effect of stiffness\, leaving other mechanical parameters such as viscoelasticity unexplored. In addition\, a large gap still remains between fundamental mechanobiological research and translational medicine. My talk will focus on how we can leverage mechanobiology for translational medicine from the cellular level to the tissue/animal level. \nFirst\, I will present the broad impacts of matrix viscoelasticity on biological processes in the context of tumor growth. These findings reveal unexplored molecular pathways involved in tumor growth and substantial force generation during cell division\, suggesting novel molecular targets for cancer treatment. Then\, I will talk about the use of mechanical stimulation as a means of therapeutic intervention\, named mechanotherapy. To this end\, we developed several designs of robotic biomedical devices capable of generating mechanical stimulation to the target tissue through highly controlled actuation. Interestingly\, mechanical stimulation was found to improve the healing process in animal models of muscle injury and atrophy through immuno-modulation and direct activation of mechanosensors. These mechanobiological approaches for medicine will open new avenues for novel therapeutics for patients and find broad utility in regenerative medicine.

However\, when robots operate in a real-world setting where the environment is dynamic and unstructured\, common assumptions used to develop the planning algorithms are no longer valid and consequently\, the safety guarantees no longer hold. In this talk\, I will describe my work on developing new theoretical tools for risk-aware\, stochastic motion planning to account for diverse and varying uncertainty descriptions while retaining the tractability of the state-of-the-art approaches. The theory has practical and scalable implementation and has been deployed not just in controlled laboratory settings but also in complex\, real-world environments. \nI will provide techniques to account for uncertainty in static\, extreme terrain and in dynamic environments. I will introduce a theoretical framework for motion planning while accounting for risk in a model predictive control setting. The risk-aware control policies are distributionally-robust to the uncertainty in the environment and have probabilistic guarantees for task completion and recursive feasibility. These techniques will be described in the context of my work deployed on ground robots for search and rescue operations in the DARPA Subterranean Challenge and for aerial vehicles in dynamic environments. The goal of my research is to develop verifiable algorithms for safety-critical autonomous systems that are able to perceive their dynamic and uncertain environments to enable safe and intelligent decision-making in hazardous or sensitive environments.

Mixed-dimensional hetero-interfaces consisting of low-dimensional material components\, have been the focus of ongoing research efforts to surpass Si-based device and to explore excitonic nano-optical phenomenon. The physical and electronic properties of these interfaces such as transitions in density of states\, intimacy of contact and localized strain\, govern the charge/energy transfer between neighboring nanomaterials\, granting them entirely new optoelectronic functions. However\, a limited understanding of the fundamental physical properties of these interfaces exists due to their deep-subwavelength nature challenged by diffraction-limit. Deep-subwavelength imaging therefore takes important role as it enables collection of nano-optical and electrical signals within a tens of nanometer range. \nIn this dissertation\, I present multiple nanoscale interfaces where scanning probe techniques effectively and directly probe the mixed-dimensional interfaces with deep-subwavelength resolution. First\, I optically investigate various nanoscale defects in as-grown MoSe2 using chemical vapor deposition\, contributing to the rational synthesis of nanomaterials by providing direct evidence of defect distribution. Second\, I introduce a universal strategy for characterizing buried semiconductor-metal contact interfaces involving 2D semiconductors and 3D metals and discuss critical factors that impact their optical and electrical properties. Third\, I exhibit localized emissions at the 2D semiconductor -metal interfaces and reveal how charge transfer significantly influences the localized states. Finally\, I provide experimental and computational evidence that strong light-matter interactions of quantum dot can be visualized using tip-enhanced nano-optical spectroscopy. The approaches presented in this dissertation offer valuable insights for studying various excitonic nanomaterial systems advancing the fields of nano-optical imaging as well as electronics based on these low-dimensional semiconductors.

This week’s presenter will be in-person as well. \nABSTRACT\nWhile it is tempting to view robotics as a nail that can be solved with the deep learning hammer\, we have seen that deep-learning based perception and action pipelines for robots are notoriously brittle and data hungry. In this talk\, I advocate for a more measured approach for designing data-driven controllers by focusing learning on task-relevant portions of the MDP. Through this philosophy\, I show that we can acquire capable learning systems that can transfer between morphologically distinct robots\, intelligently probe the environment for imperceptible reward signals\, and perform deep exploration with no priors.

Decisions must be made based on imperfect information about the environment and with uncertainty about how the environment will evolve. In addition\, these systems must carefully balance safety with other considerations\, such as operational efficiency. Typically\, the space of edge cases is vast\, placing a large burden on human designers to anticipate problem scenarios and develop ways to resolve them. This talk discusses major challenges associated with ensuring computational tractability and establishing trust that our systems will behave correctly when deployed in the real world. We will outline some methodologies for addressing these challenges and point to some research applications that can serve as inspiration for building safer systems.

Much of this challenge stems from the fact that term rewriting\, a ubiquitous approach to manipulating programs\, only works with one version of a program at a time. As a result\, the system builder must carefully consider every program manipulation\, lest they accidentally “take a wrong turn” and miss out on optimization opportunities. For non-PL-experts\, these difficulties prevent application of PL techniques to domains that might otherwise greatly benefit from them. \nThis talk will describe a data structure called the e-graph and a technique called equality saturation that together allow one to store and manipulate many equivalent versions of a program simultaneously. Recent advances like delayed congruence closure and lattice-based “e-class analyses”\, both embodied in the egg e-graph toolkit\, have made this approach fast and flexible enough for academic and industrial use in areas including deep learning\, carpentry\, 3D design\, and floating point arithmetic. This talk will also present recent discoveries that connect equality saturation to relational databases. The result is faster\, simpler\, and theoretically optimal implementations of equality saturation.

Prior methods try to learn both a representation and a downstream task jointly from data sets of human behavior\, but this unfortunately picks up on spurious correlations and results in behaviors that do not generalize. In my view\, what’s holding us back from successful human-robot interaction is that human and robot representations are often misaligned: for example\, our lab’s assistive robot moved a cup inches away from my face — which is technically collision-free behavior — because it lacked an understanding of personal space. Instead of treating people as static data sources\, my key insight is that robots must engage with humans in an interactive process for finding a shared representation for more efficient\, transparent\, and seamless downstream learning. In this talk\, I focus on a divide and conquer approach: explicitly focus human input on teaching robots good representations before using them for learning downstream tasks. This means that instead of relying on inputs designed to teach the representation implicitly\, we have the opportunity to design human input that is explicitly targeted at teaching the representation and can do so efficiently. I introduce a new type of representation-specific input that lets the human teach new features\, I enable robots to reason about the uncertainty in their current representation and automatically detect misalignment\, and I propose a novel human behavior model to learn robust behaviors on top of human-aligned representations. By explicitly tackling representation alignment\, I believe we can ultimately achieve seamless interaction with humans where each agent truly grasps why the other behaves the way they do.

These quantum effects challenge our understanding of nature and open up new possibilities for future technologies in quantum information. In my talk\, I will discuss the use of van der Waals (vdW) heterostructures to create new quantum materials. These heterostructures\, made by mechanically assembling layers of two-dimensional materials together\, offer a new way to create quantum matter and break through traditional material synthesis limitations. \n\nI will present two examples of this approach. In the first example\, I will illustrate how Coulomb interactions across separate atomic layers pair fermions (electrons and holes) into bosons to achieve a superfluid condensate state. The second example will introduce the concept of moiré band engineering\, where the interference between two atomic lattices reforms electronic band structures and creates new electronic orders. Finally\, I will briefly discuss applications of local probe techniques to uncover hidden quantum properties in vdW platforms and share visions of leveraging rich interplays across atomic interfaces to create new quantum states of matter\, new quantum devices\, and new local measurements.

Personalized medical devices\, tissue grafts\, biomonitoring systems\, and precision medicine are customized based on each patient’s needs and health background. However\, the current manufacturing techniques are challenged when it comes to fabricating architected structures with complex designs. Additive manufacturing has been a strong tool for fabricating such architectures for tissue regenerative applications. In combination with sacrificial biomanufacturing\, functional living materials are developed with 3D internal permeable macrochannels that enable nutrition transfer for prolonged cell viability. Conventional approaches for implantation of fully functional 3D printed tissue constructs require invasive surgeries\, raising the need for more efficient alternative biomanufacturing technologies. Sound in vivo printing is a unique solution that enables printing tissue scaffolds deep inside the body where in lieu of open surgeries\, the target organs can be reached through minimally invasive devices such as catheters to deliver biomaterials. For this purpose\, focused ultrasound-triggered crosslinking is used for creating complex biostructures centimeters deep into the organs. Next-generation in vivo printing technology enables a smart biomanufacturing scheme for a wide range of functional biomaterials for applications in tissue regeneration\, bioelectronics\, drug delivery\, etc. URL:https://seasevents.nmsdev7.com/event/meam-seminar-additive-manufacturing-future-of-healthcare/ LOCATION:Wu and Chen Auditorium (Room 101)\, Levine Hall\, 3330 Walnut Street\, Philadelphia\, PA\, 19104\, United States CATEGORIES:Seminar ORGANIZER;CN="Mechanical Engineering and Applied Mechanics":MAILTO:meam@seas.upenn.edu END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20230320T130000 DTEND;TZID=America/New_York:20230320T140000 DTSTAMP:20260404T195000 CREATED:20230111T151303Z LAST-MODIFIED:20230111T151303Z UID:10007423-1679317200-1679320800@seasevents.nmsdev7.com SUMMARY:PSOC Seminar: "Adventures in Cellular Herding: from flocks of cells to bioelectric shepherds" (Daniel J.

Specifically for CAR T cell therapy\, genetic coding material (e.g. DNA\, mRNA) is inserted into the T cells to express chimeric antigen receptors to target biomarkers of cancer cells and trigger an activated immune response towards the tumor of interest. This process that starts from blood drawn from one person and ends with specialized engineered cells delivered to the same patient includes multiple tedious and costly steps\, and can require a long time that the patient may not have. Microfluidics techniques are being developed that can address all steps of this cell manufacturing process\, including cell harvesting\, cell isolation\, cell activation and expansion\, and cell transfection. In this talk I will introduce two microfluidic platforms in my lab\, one is the lateral cavity acoustic transducer (LCAT) and the other is droplet microfluidics. LCAT was used for processing blood samples\, isolating T cells\, transfecting T cells\, and finally expanding T cells to scale up for treatment. Based on LCAT\, we developed the acoustic electric shear orbiting poration (AESOP) device to uniformly deliver genetic cargo dosage into a large population of cells simultaneously. Based on droplet microfluidics we constructed a single cell artificial antigen presenting cells (aAPCs) for T cell activation. By trapping single cells in microfluidic compartments\, we are able to study the cell morphology and cell-cell communications to further understand immune cell activation and immune cell synapses.

This week’s presenter will be in-person as well. \n  \nABSTRACT\nAutonomous systems of the near future have the potential to impact and improve our lives in unprecedented ways. As an example\, an autonomous taxi service can be instructed to take the socially responsible route minimizing congestion (and associated carbon emissions) instead of the purely selfish shortest route. In order for such a system to be robust and gain public acceptance\, it is critical that it respects the users’ personal incentives\, as well as ensures that different users enjoy equitable service. Until now\, the vast majority of incentive schemes used in engineering systems have been monetary. Examples include road-tolling to reduce traffic congestion\, surge-pricing to manage excessive demand in ride-hailing\, and time-varying energy tariffs to encourage consumption off peak hours. In this talk\, we argue that the use of money in engineering systems is fundamentally flawed. The sensitivity of users to money can vary widely for factors outside the system (e.g.\, income and inter-generational wealth accumulation)\, and therefore monetary schemes implicitly favor the wealthy. We introduce the concept of a self-contained karma economy as an alternative incentive scheme. In a karma economy\, each user is endowed with tokens (called karma) that are non-tradable for money\, and the users repeatedly obtain or yield a preferential service in exchange of karma. We demonstrate this concept on the stylized yet insightful example of autonomous intersection management\, where an agent passing first in an intersection transfers karma to that yielding. We lay the mathematical foundations that ensure that such an economy is well-defined and the strategic behavior of its users (i.e.\, how much karma they spend) can be predicted. We then analyze the performance of the karma economy in numerical case studies\, showcasing that it achieves socially efficient outcomes in a self-contained\, and thereby equitable\, manner.

Today\, we build systems with hundreds of heuristics but often do not understand their inherent and emergent behaviors. I will present a set of tools and techniques to prove performance properties of heuristics running in real-world conditions. Rigorous proofs can not only inspire confidence in our designs\, but also give counter-intuitive insights about their performance. \nA key theme in our approach is to model uncertainty in systems using non-random\, non-deterministic objects that cover a wide range of possible behaviors under a single abstraction. Such models allow us to analyze complex system behaviors using automated reasoning techniques. I will present automated tools to analyze congestion control and process scheduling algorithms. These tools prove performance properties and find counter-examples where widely deployed heuristics fail. I will also show that current end-to-end congestion control algorithms that bound delay cannot avoid starvation and present a method to beamform wireless signals using thousands of antennas.

While this diversity enables unprecedented flexibility\, it also requires domain-experts to learn how to customize programs to efficiently leverage the latest platform-specific API’s and data structures\, instead of working on their intended problem. Rather than forcing each user to bear this burden\, I propose building high-level abstractions within general-purpose compilers that enable fast\, portable\, and composable programs to be automatically generated. \nThis talk will demonstrate this approach through compilers that I built for two domains: automatic differentiation and parallelism. These domains are critical to both scientific computing and machine learning\, forming the basis of neural network training\, uncertainty quantification\, and high-performance computing. For example\, a researcher hoping to incorporate their climate simulation into a machine learning model must also provide a corresponding derivative simulation. My compiler\, Enzyme\, automatically generates these derivatives from existing computer programs\, without modifying the original application. Moreover\, operating within the compiler enables Enzyme to combine differentiation with program optimization\, resulting in asymptotically and empirically faster code. Looking forward\, this talk will also touch on how this domain-agnostic compiler approach can be applied to new directions\, including probabilistic programming.

Strong excitonic responses in transition metal dichalcogenides (TMDs) allow optical access to the wealth of physics. In this talk\, I will present our recent results about interactions between excitons and charge carriers trapped in moiré potentials. We have discovered novel exciton many-body ground states composed of moiré excitons and correlated electron lattices\, resulting from new interaction between exciton and charges enabled by unusual quantum confinement in 2D moiré superlattices. The interaction further enriches the magnetic phases in such moiré superlattices. We have observed that the spin-spin interactions between moiré trapped holes can be drastically tuned by optical excitation power. The mechanism points to the unique excitons-mediated long-range exchange interaction between moiré trapped carriers. This discovery adds a new and dynamic tuning knob to the rich many-body Hamiltonian of moiré quantum matter. Our work provides the framework for understanding and engineering electronic and excitonic states in moiré quantum matters.

These emissions arise not only due to the energy requirements of chemical synthesis\, but since hydrocarbon feedstocks can be overoxidized or used as hydrogen sources. Using renewable electricity to drive chemical synthesis may provide a route to overcoming these challenges\, enabling synthetic routes which operate at benign conditions and utilize sustainable inputs. We are developing an electrosynthetic toolkit in which distributed feedstocks\, including carbon dioxide\, dinitrogen\, water\, and renewable electricity\, can be converted into diverse fuels\, chemicals\, and materials. \nIn this presentation\, we will first share recent advances made in our laboratory on nitrogen fixation to synthesize ammonia at ambient conditions. Specifically\, our lab has investigated a continuous lithium-mediated approach to ammonia synthesis and understood the reaction network that controls selectivity. We have developed non-aqueous gas-diffusion electrodes which lead to high rates of ammonia synthesis at ambient conditions. Then\, we will discuss how water can be used as a sustainable oxygen-atom source and how carbon dioxide can be used to achieve carbon chain extension. These findings will be discussed in the context of a broader range of electrosynthetic transformations which could lead to local and on-demand production of critical chemicals and materials. \nBio: \nKarthish Manthiram is a Professor of Chemistry and Chemical Engineering at Caltech.

The COVID-19 pandemic has uprooted the mode and method of human communication and interaction. The magnitude of the pandemic has led to an ‘infodemic’ along with considerable increase in stress and anxiety across communities. At the same time\, the use of social media has increased dramatically as individuals sheltered in place. In this talk\, I will introduce how our group is using big data from social media sources for contributing to social good. I will discuss the application of machine learning and natural language processing techniques to obtain insights on the heterogeneity in vaccine acceptance and mental health measurement across communities in the United States and outside.

With the rise of big data and machine learning\, more and more developers must build applications that involve complex and data-intensive distributed processing. \nIn this talk\, I will discuss the design of a general-purpose distributed execution system that can serve as a common platform for such applications. Such a system offers two key benefits: (1) common system functionality such as distributed resource management can be shared across different application domains\, and (2) by building on the same platform\, applications across domains can easily interoperate. \nFirst\, I will introduce the distributed futures interface\, a powerful yet expressive distributed programming abstraction for remote execution and memory. Second\, I will introduce ownership\, an architecture for distributed futures systems that simultaneously provides horizontal scalability\, low latency\, and fault tolerance. Finally\, I will present Exoshuffle\, a large-scale shuffle system that builds on distributed futures and ownership to match the speed and reliability of specialized data processing frameworks while using an order of magnitude less code.

Early iterations of wearables from the 50s and 60s primarily took the form of rigid exoskeletons; however\, in the past twenty years\, a growing subset of this field has transitioned to the use of soft components and materials to improve portability\, accessibility\, fit\, and comfort\, guided in part by advances in the related field of soft robotics. Based on the unique requirements for wearables\, including personalization for varied bodies and low cost for accessibility\, automated and highly customizable textile-compatible materials and manufacturing strategies must be developed to support the fabrication and integration of all the necessary components (sensors\, actuators\, interconnections). This seminar will explore the intersection of knowledge from the field of textile materials and manufacturing with the needs of soft robots and devices\, specifically focusing on wearable applications\, including performance metrics\, material and component choices\, and fabrication strategies. Several integrated design and fabrication platforms will be presented in the context of their ability to create constituent components for wearable robots and devices.

However\, fundamental limitations in the efficient miniaturization of macro-scale robotic technologies require bioinspired/hybrid approaches for actuation\, sensing\, and control of microrobots. Recent advances in materials\, fabrication and actuation technologies have enabled the realization of wireless microrobots powered by external fields\, biological organisms\, and catalytic reactions. In the first part of this talk\, I will introduce cell-sized (<10 µm) surface-rolling multifunctional microrobots\, inspired by leukocytes in the circulatory system\, actuated by external magnetic fields. Microrollers generate unprecedented strong propulsion (up to 100 body lengths per second) enabling their upstream navigation in physiological blood flow and their functionalization with targeting agents and drug molecules allows targeted\, on-demand drug delivery to desired cells. In the second part\, I will present reprogrammable shape morphing of small-scale magnetic soft machines enabled by heat-assisted high-resolution (<40 µm)\, discrete\, and 3D magnetic encoding. Heat-assisted magnetic programming allows experimental optimization of the functional behavior of small-scale soft systems\, including reconfigurable mechanical behavior of an auxetic metamaterial structure\, tunable locomotion of a surface-walking soft robot\, and adaptive grasping of a soft gripper. I will conclude the talk with a stimulating discussion on a path forward toward bio-integrated robotics at cellular and tissue scales for healthcare applications beyond targeted therapeutic delivery.

At the same time\, the end of Dennard scaling is sunsetting traditional performance gains commonly attained with reduction in transistor feature size. Faced with these challenges\, my research is building a heterogeneity of solutions co-optimized across the algorithm\, memory subsystem\, hardware architecture\, and silicon stack to generate breakthrough advances in arithmetic performance\, compute density and flexibility\, and energy efficiency for on-chip machine learning\, and natural language processing (NLP) in particular. I will start\, in the algorithm front\, by discussing award-winning work on developing a novel floating-point based data type\, AdaptivFloat\, which enables resilient quantized AI computations; and is particularly suitable for NLP networks with very large parameter distribution. Then\, I will describe a 16nm chip prototype that adopts AdaptivFloat in the acceleration of noise-robust AI speech and machine translation tasks – and whose fidelity to the front-end application is verified via a formal hardware/software compiler interface. Towards the goal of lowering the prohibitive energy cost of inferencing large language models on TinyML devices\, I will describe a principled algorithm-hardware co-design solution\, validated in a 12nm chip tapeout\, that accelerates Transformer workloads by tailoring the accelerator’s latency and energy expenditures according to the complexity of the input query it processes. Finally\, I will conclude with some of my current and future research efforts on further pushing the on-chip energy-efficiency frontiers by leveraging specialized non-conventional dynamic memory structures for on-device training — and recently prototyped in a 16nm tapeout.

However\, existing electrode architectures cannot simultaneously achieve thick electrodes with high active material volume fractions and good power. These particle-based architectures rely on electrolyte transport within the pores of the cathode to fully lithiate active material particles during discharge. As cathode solid volume fractions approach 100%\, batteries experience electrolyte depletion which leads to inaccessible cathode reaction sites. The additional theoretical capacity that comes from increased cathode density\, therefore\, is impractical if that energy cannot be fully extracted. \nWe combine experiments and simulations of high density and high thickness cathodes to understand the transport and performance trade-offs of LIBs as the cathode solid volume fraction approaches 100%\, which we use to reveal the cathode properties needed to achieve high performance at high relative density and thickness. We use one- and two-dimensional simulations to compare the discharge performance of two cathode architectures\, a traditional particle-based architecture and a continuous cathode architecture created via electrodeposition. We show that there is a large opportunity space for improved energy density at high relative densities by using new electrode manufacturing techniques to create continuous diffusion pathways and high diffusivities. \nThis work uses a comparative analysis of cathode architectures to explore the interdependent impact of solid volume fraction\, solid-diffusivity\, cathode thickness\, and discharge rate on lithium-ion battery areal capacity. We should how a combination of high diffusivity and continuous solid-state diffusion pathways provides an exciting path for realizing ultra-dense and thick cathodes with high energy density.

This week’s presenter will be in-person as well.  \n  \nABSTRACT\nMy long-term research goal is enable real robots to manipulate any kind of object such that they can perform many different tasks in a wide variety of application scenarios such as in our homes\, in hospitals\, warehouses\, or factories. Many of these tasks will require long-horizon reasoning and sequencing of skills to achieve a goal state. While learning approaches promise generalization beyond what the robot has seen during training\, they require large data collection – a challenge when operating on real robots and specifically for long-horizon tasks. In this talk\, I will present our work on enabling long-horizon reasoning on real robots for a variety of different long-horizon tasks that can be solved by sequencing a large variety of composable skill primitives. We approach this problem from many different angles such as (i) using large-scale\, language-annotated video datasets as a cheap data source for skill learning; (ii) sequencing these learned skill primitives to resolve geometric dependencies prevalent in long-horizon tasks; (iii) learning grounded predicates thereby enabling closed-loop\, symbolic task planning.
