SUMMARY:MEAM Seminar: "Cell Polarization and Growth"
DESCRIPTION:Polarization is an essential behavior of living cells\, yet the dynamics of this symmetry-breaking process are not fully understood. We have developed a spatial stochastic model of cellular polarization during mating of Saccharomyces cerevisiae. Specifically we investigated the ability of yeast cells to sense a spatial gradient of mating pheromone and respond by forming a projection in the direction of the mating partner. Our results demonstrate that a spatial stochastic model of polarisome formation can more robustly reproduce two fundamental characteristics observed in wild-type cells: a tightly polarized phenotype and the ability to track moving pheromone input\, in comparison with the corresponding deterministic model. \nExisting models of cell polarization have focused solely on the biochemical signaling system. However\, there exists a well-known interplay between the growth of the mating projection and the mechanical forces of the cell wall in determining the shape of the cell. The cell wall of S. cerevisiae both defines its shape and provides the mechanical integrity necessary to sustain the large internal turgor pressure. Under the isotropic push of turgor pressure\, polarized expansion occurs via localized assembly of new cell wall material in combination with a simultaneous softening of the cell wall\, inducing it to yield and locally expand. Intracellular signaling directs enzymes with the ability to modify cross-linking of polymers in the cell wall to the region of polarization. The resulting mechanical feedback from the wall expansion initiates the delivery of raw material via vesicular transport. \nTo accurately model this complex biological phenomena\, we have developed a multiscale computational framework for simulating the coupling of the stochastic dynamics of biochemical reactions involved in shaping walled cells to the mechanical processes of cell wall expansion and growth. Our computational method exploits the time-scale separation between the relatively slow dynamics of the cell wall and the rapid interactions of the intercellular signaling network.

SUMMARY:ESE Seminar: "Nanophotonics: A High Bandwidth Optical Neural Interface"
DESCRIPTION:Abstract\nLight is a powerful tool for interrogating and manipulating biological systems\, enabling targeted\nstimulation\, sensing\, and imaging. Optical methods such as optogenetics have transformed the study of\nneural circuits by making it possible to control neural activity using light. However\, there remains a critical\ndemand in research and medicine for miniaturized high resolution optical tools that can be embedded\ndeep within biological systems like the brain. The brain poses particular challenges due to the sheer\nnumber of densely packed interconnected neurons and the strong tissue scattering and absorption of\nlight. Nanophotonics\, or chip-scale optical circuits\, can enable unprecedented spatiotemporal resolution\nby leveraging nanoscale coherent control of a large set of optical channels within subwavelength\nwaveguides with high speed reconfiguration capability\, potential for integration with electronics\, and low-\ncost scalable manufacturability. This potential high bandwidth optical neural interface can be as thin as a\nfew neurons and have the ability to test spatial\, temporal\, and cell-type-specific aspects of neural\nencoding from cellular to system level within the brain. \nI will present the first implantable nanophotonic probe for optogenetic stimulation and recording of\nneurons in live mice. To achieve this\, we developed a reconfigurable visible nanophotonic platform based\non phase-controlled silicon nitride interferometric waveguide structures that can control cellular-sized\ncoherent emitters at blue wavelengths (peak of optogenetic actuators)\, far from traditional infrared\nwavelengths. This enabled a neural interface that can generate and read multi-neuron spike patterns\ndeep within the brain with single-cell and sub-millisecond resolution\, the highest resolution\nneuromodulation shown with an implantable probe. \nIn addition\, I will highlight two building blocks for future nanophotonic stimulation and sensing\ndevices that I developed using this platform: wide-angle chip-scale visible beam steering and multiplexing\nwithin a single waveguide by utilizing the transverse spatial degree-of-freedom of light. I will show how\nprecise phase control and novel nanoscale photonic design of these building blocks has been applied to\nemerging high bandwidth optical applications like portable display technology and quantum optical\nsystems. Finally\, I will present a future outlook towards a new generation of implantable and wearable\nbiomedical devices based on nanophotonic 3D light projection and sensing techniques including high-\ndimensional multiplexing\, volumetric beam shaping\, and quantum sensing.

SUMMARY:Technology\, Business and Government Lecture Series: Aerospace Prizes Inspire the Five I's of Success
DESCRIPTION:The United States’ future economic growth and competitiveness depend on our capacity to inno­vate. Americans believe that it is possible to create jobs in the aerospace and defense industry by doing what the United States does well\, which is cultivating the creativity and innovative processes developed by its people. Innovation and entrepreneurship in the aerospace and defense industries have historically kept the US at the forefront of technology advances\, which has spurred economic growth\, and created entirely new industries such as commercial transportation of cargo and humans\, uninhabited aerial systems for civilian and military missions\, and more recently private commercial space.  Where would we be without aviation pioneers and innovators such as Amelia Earhart\, Glenn L. Martin\, William Boeing\, Charles Lindbergh\, Igor Sikorsky and Elon Musk?  A key catalyst that inspires innovation and entrepreneurship in the aerospace field has been the establishment of aerospace prizes and competitions to accelerate the five I’s:  imagination\, invention\, innovation\, investment\, and impact.  This presentation details three aerospace prizes that not only advanced technology in the aerospace field\, but also spurred significant job growth and economic development in the United States.  More importantly\, these prizes often attracted a new generation of students and technology innovators to the field with the hope of becoming the first to win a prize\, while making a significant contribution to the aerospace field and to society. \nThis lecture is part of Penn Engineering’s Technology\, Business\, and Government Lecture Series. Recognizing an increasingly significant inter-relationship between the rapid growth of new technologies and the business and governmental sectors\, the Technology\, Business and Government Lecture Series brings distinguished individuals to Penn Engineering to interact with students and faculty on broad issues affecting technology and science\, research and policy. \n

SUMMARY:CIS Seminar: One Size Doesn’t Fit Anyone: Tailoring Digital Tools for Personal Health Journeys
DESCRIPTION:Abstract \nPersonal technologies for everyday health management have the potential to transform healthcare by\nempowering individuals to engage in their own care\, scaffolding access to critical information\, and\nsupporting patient-centered decision-making. Currently\, many personal health tools often focus only on a\nsingle task or isolated event. However\, chronic illnesses are characterized by information needs and\nchallenges that shift over time; thus\, these illnesses are better defined as a dynamic trajectory than a series\nof singular events.\nIn this talk\, I discuss my work designing and implementing novel computing systems that: 1) support\nchronic illness trajectories and 2) reduce patients’ barriers to health information access. I’ll present my\napproach using personalized and adaptive content to connect individuals with timely and actionable\nfeedback. Using results from longitudinal field deployments\, I demonstrate the ability for these tools to\nfacilitate patients’ proactive health management and engagement in their care. I’ll also discuss the utility\nof this approach for encouraging to long-term engagement with health tools\, as evidenced by longitudinal\nusage patterns. I’ll conclude with opportunities for using personalization as a strategy to support other\ncomplex information tasks\, including the health management of illness trajectories in which uncertainty is\nparamount and the integration of machine learning models into clinical workflows.

SUMMARY:CBE Faculty Candidate Seminar: Decomposition: Exploiting Structure in Chemical Systems to Solve Challenging Decision-Making Problems"
DESCRIPTION:Abstract: \nComputational optimal decision-making tools are essential for ensuring that systems are designed\, operated\, and controlled in an economic and sustainable manner. Using optimization to make decisions for chemical and energy systems is particularly challenging due to the inherent presence of nonlinear process physics\, both integer and continuous decisions\, uncertainties in important parameters\, and multiple relevant time scales. This talk addresses the method of decomposition\, which solves large\, computationally challenging decision-making problems through a set of smaller\, easier-to-solve subproblems. The first half of this talk addresses the problem of identifying smaller subproblems that make the large problem easy to solve. An algorithmic framework for automatically doing so using community detection\, a concept from network theory\, is presented. The superiority of using community-based decompositions to solve optimization problems\, compared to other intuition-based decompositions\, is showcased through an optimal model predictive control case study. The ability of the algorithm to identify subproblems when an intuitive decomposition does not exist is also demonstrated. The second part of the talk addresses the challenge of coordinating subproblems to arrive at a solution of the original problem. Here\, a branch-and-price algorithm which can solve certain classes of nonconvex mixed integer nonlinear programs (the most challenging type of optimization problem to solve) to global optimality is presented. The applicability of this algorithm to many problems of chemical engineering interest\, including process design under uncertainty\, multiperiod capacity planning\, dynamic facility location\, and task assignment to process units\, is demonstrated.

SUMMARY:MSE Faculty Candidate Seminar: "Uncovering atomistic mechanisms of crystallization using Machine Learning"
DESCRIPTION:Solid-liquid interfaces have notoriously haphazard atomic environments. While essentially amorphous\, the liquid has short-range order and heterogeneous dynamics. The crystal\, albeit ordered\, contains a plethora of defects ranging from adatoms to dislocation-created spiral steps. All these elements are of paramount importance in the crystal growth process\, which makes the crystallization kinetics challenging to describe concisely in a single framework. In this seminar I will introduce a novel data-driven approach to systematically detect\, encode\, and classify all atomic-scale crystallization mechanisms described above. I will also show how this approach naturally leads to a predictive kinetic model of crystallization that takes into account the entire zoo of microstructural elements present at solid-liquid interfaces. In this innovative application of data science to materials Machine Learning is employed as an aid to augment human intuition\, rather than a substitute thereof. The result is an approach that blends prevailing scientific methods with data-science tools to produce physically-consistent models and conceptual knowledge.
