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.

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:20230321T103000 DTEND;TZID=America/New_York:20230321T113000 DTSTAMP:20260404T194313 CREATED:20230217T172905Z LAST-MODIFIED:20230217T172905Z UID:10007485-1679394600-1679398200@seasevents.nmsdev7.com SUMMARY:BE Undergraduate Student Focus Group DESCRIPTION:Attention BE Master’s Students!

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.

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.

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.

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.

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.

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.

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.

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.

I will discuss several examples that highlight the remarkable potential of engineered two-dimensional (2D) materials for exploring novel quantum phases of matter driven by strong correlation and non-trivial topology using scanning tunneling microscopy (STM). I will first discuss our recent work on visualizing and manipulating 1D chiral edge states in a moiré quantum anomalous Hall (QAH) insulator of twisted monolayer-bilayer graphene (tMBLG). Here spectroscopic mapping allows us to directly identify QAH edge states\, while combining electrostatic gating and tip-induced doping enables us to create and manipulate QAH edge states on-demand. I will also discuss the interplay between quantum confinement and strong correlation in engineered 1D twin-boundary defects of semiconducting 1H-MoSe2 \, which allows direct spectroscopic imaging of spin-charge fractionalization due to the formation of a 1D Tomonaga-Luttinger liquid.  I will conclude by providing a glimpse into new avenues of 2D materials engineering involving advanced atomically-precise characterization in the growing field of quantum materials.

In this talk\, I’ll show how data-driven sensorimotor controllers can push quadcopters with only onboard sensing and computation to their physical limits. Such controllers enable quadcopters to fly faster and more agile than what was possible before in unstructured environments like cities\, forests\, and disaster scenarios. The insights acquired from quadcopter flight transfer to other domains\, including legged locomotion and bio-inspired vision. However\, fundamental research questions still need to be addressed to make agile robots adaptable\, robust\, and safe\, and enable their wider application in homes\, search and surveillance\, and inspection.

However\, these models are typically created by resource-rich research groups that unilaterally decide how a given model should be built\, trained\, and released\, after which point it is never updated. In contrast\, open-source development has demonstrated that it is possible for a community of contributors to work together to iteratively build complex and widely used software. This kind of large-scale distributed collaboration is made possible through a mature set of tools including version control and package management. In this talk\, I will discuss a research focus in my group that aims to make it possible to build machine learning models in the way that open-source software is developed. Specifically\, I will discuss our preliminary work on merging multiple models while retaining their individual capabilities\, patching models with cheaply-communicable updates\, designing modular model architectures\, and tracking changes through a version control system for model parameters. I will conclude with an outlook on how the field will change once truly collaborative\, communal\, and continual machine learning is possible.

This week’s presenter will be in-person as well. \nABSTRACT\nA key challenge to the widespread deployment of robotic manipulators is the need to ensure safety in arbitrary environments while generating new motion plans in real-time. This talk describes a technique that constructs a parameterized representation of the forward reachable set that it then uses in concert with predictions to enable certified\, collision checking. To improve computational speed\, this talk describes how to represent this parameterized reachable set using a neural implicit representation without sacrificing any safety guarantees. This approach\, which is guaranteed to generate safe behavior\, is demonstrated across a variety of different real-world platforms including ground vehicles\, manipulators\, and walking robots.

Such combinations of properties are often found in the biological world. Organisms from nature construct a variety of different biological structural materials for protection\, predation\, body support\, camouflage\, etc. Despite the fact that these materials are made from limited constituent materials with usually poor intrinsic mechanical properties\, such as brittle minerals and soft biopolymers\, biological materials are often able to achieve remarkable mechanical properties while offering additional functionalities simultaneously\, such as low density\, coloration\, transparency\, flexibility\, visual sensitivity\, etc. In this talk\, I will present our recent work in elucidating the fundamental structure-property relationships in some natural structural materials by focusing on their strategies in achieving damage tolerance\, weight reduction\, and multifunctionality. In particular\, I will present a unique damage-tolerant\, dual-scale\, single-crystalline\, low-density microlattice that we recently discovered in an echinoderm skeletal system. Our research combines quantitative multiscale 3D structural analysis\, in-situ mechanical analysis\, theoretical and computational modeling\, and design and manufacturing of bio-inspired materials. I hope this talk can stimulate more discussions among research areas such as material synthesis\, biomimetics\, mechanics\, biology\, and manufacturing.

In this talk\, I will describe methods that provide these ingredients and serve as building blocks for enabling self-sufficient robot learning. \nFirst\, I will outline a family of methods that facilitate active global exploration. Specifically\, they enable ultra data-efficient Bayesian optimization in reality by leveraging experience from simulation to shape the space of decisions. In robotics\, these methods enable success with a budget of only 10-20 real robot trials for a range of tasks: bipedal and hexapod walking\, task-oriented grasping\, and nonprehensile manipulation. \nNext\, I will describe how to bring simulations closer to reality. This is especially important for scenarios with highly deformable objects\, where simulation parameters influence the dynamics in unintuitive ways. The success here hinges on finding a good representation for the state of deformables. I will describe adaptive distribution embeddings that provide an effective way to incorporate noisy state observations into modern Bayesian tools for simulation parameter inference. This novel representation ensures success in estimating posterior distributions over simulation parameters\, such as elasticity\, friction\, and scale\, even for scenarios with highly deformable objects and using only a small set of real-world trajectories. \nLastly\, I will share a vision of using distribution embeddings to make the space of stochastic policies in reinforcement learning suitable for global optimization. This research direction involves formalizing and learning novel distance metrics on this space and will support principled ways of seeking diverse behaviors. This can unlock truly autonomous learning\, where learning agents have incentives to explore\, build useful internal representations and discover a variety of effective ways of interacting with the world.

However\, the efficacy of these therapies remains limited\, as challenges associated with off-target drug toxicity\, poorly controlled drug pharmacokinetics\, and an incomplete understanding of real-time therapy responses prevent effective therapeutic windows from being realized. Here\, I will highlight some of our work on the design\, fabrication\, and characterization of biomaterial-based delivery technologies for the controlled delivery of combination immunotherapies and for the non-invasive monitoring of their associated immune responses for cancer therapy. We show that the design of materials and their delivery context can influence therapeutic outcomes and alter the spatiotemporal characteristics of the incited immunomodulatory responses. By adroitly designing and utilizing our material delivery platforms\, we can deliver immunotherapies with tailorable pharmacokinetics and enhanced efficiency to improve long-term therapeutic outcomes and tolerability and enable studying basic questions in immunobiology as we seek to generate a ‘living’ therapeutics.

This week’s presenter will be in-person as well.  \n  \nABSTRACT\nRobots are getting smarter at converting complex natural language commands describing household tasks into step-wise instructions. Yet\, they fail to actually perform such tasks! A prominent explanation for these failures is the fragility and inability of the low-level skills (e.g.\, locomotion\, grasping\, pushing\, object re-orientation\, etc.) to generalize to unseen scenarios. In this talk\, I will discuss a framework for learning low-level skills that surpasses limitations of current systems at tackling contact-rich tasks and is real-world-ready: generalizes\, runs in real-time with onboard computing\, and uses commodity sensors. I will describe the framework using the following case studies: \n(i) a dexterous manipulation system capable of re-orienting novel objects. \n(ii) a quadruped robot capable of fast locomotion and manipulation on diverse natural terrains. \n(iii) learning from a few task demonstrations of an object manipulation task to generalize to new object instances in out-of-distribution configurations.

This week’s presenter will be in-person as well.  \n  \nABSTRACT\nThis talk will summarize key recent advances in autonomous surface and aerial mobility for Mars exploration\, then discuss potential future missions and technology needs for Mars and other planetary bodies. Among recent advances\, the Perseverance rover that is now operating on Mars includes new autonomous navigation capability that dramatically increases its traverse speed over previous rovers. Perseverance also carried the Ingenuity helicopter to Mars\, which is a technology demonstration of the first heavier-than-air aircraft ever to operate on another planet. The current mission objective for Perseverance involves driving a total distance of about 60 kilometers in about 10 Earth years. Rover mission concepts recently suggested for the Moon would drive about 1500 to 2000 km in under 4 years\, which requires significant advances in autonomy. Successors to the Ingenuity helicopter are now under development for use in a mission planned for later this decade to return Mars samples to Earth that Perseverance is collecting. Much larger helicopter concepts are being studied to enable carrying larger science instrument payloads for potential future Mars missions. Robotic surface and aerial vehicles\, as well as drilling systems for subsurface access\, potentially could play a role in NASA’s goals for a human mission to Mars roughly two decades from now.

However\, due to extreme disparity of scales present in high-Reynolds-number wall-bounded turbulent flows\, any attempt to simulate these flows directly on a computational grid without resorting to modeling of some sort results in prohibitively large computational cost. Wall-modeled large-eddy simulation (WMLES) show perhaps the most promise in being able to capture more of the relevant flow physics while keeping computational cost tractable in simulating these flows. There have been many novel wall models being developed during the last decades. However\, the applications of most of the models are limited to canonical two-dimensional turbulent flows such as the turbulent channel flow where non-equilibrium effects including pressure gradient and mean-flow three-dimensionality are missing. \nIn this talk\, I will present a comparative study of WMLES of a turbulent boundary layer with mean-flow three-dimensionality developing on the floor of a bent square duct which mimics the flow over the swept wing of the aircraft. The predictive capabilities of three widely used wall models\, namely\, a simple equilibrium stress model\, an integral nonequilibrium model\, and a PDE nonequilibrium model\, have been investigated. These models potentially span the complete spectrum of wall models with varying physical details and complexity. While the wall-stress magnitudes predicted by the three wall models are comparable\, the PDE nonequilibrium wall model produces a substantially more accurate prediction of the wall-stress direction\, followed by the integral nonequilibrium wall model. The wall-stress direction from the wall models is shown to have separable contributions from the equilibrium stress part and the integrated nonequilibrium effects\, where how the latter is modeled differs among the wall models. Budget analyses have been conducted to elucidate precise mechanisms by which the three wall models produce different predictions of the wall shear stress directions given almost identical inputs. The physical characteristics of the three-dimensional turbulent boundary layer including the generation mechanism of mean-flow three-dimensionality and the anisotropy of turbulence will also be discussed in the talk.
