    • MEAM Seminar: “Microdevices Enabled by Rarefied Flows”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    In this talk we will review emerging applications of rarefied gas dynamics for microscale sensing, actuation and power generation. Performance of conventional fluidic devices such as pumps, combustors and heat engines decreases at the microscale due to greater viscous and heat transfer losses. Unconventional micro/nanodevices exploit the tight coupling between non-equilibrium gas, liquid and solid-state […]

    MSE Faculty Candidate Seminar: “Unsupervised Learning of Dislocation Motion”

    /
    Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

    High-performance designs that utilize metallic alloys are driving a need to quantify deformation in-situ at the finest length scales in order to reduce weight, increase operating temperatures, and improve fatigue life. With improvements to data reconstruction algorithms, brighter X-ray sources, and more efficient detectors, these in-situ studies of microstructural and micromechanical evolution in 3-D (nm-µm […]

    CBE Faculty Candidate Seminar: “Understanding and Controlling the Complexity of Catalytic Active Sites”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Abstract: Heterogeneous catalysis is of central importance to the global economy today, facilitating the conversion of raw materials into valuable fuels and chemicals, and the abatement of chemical pollutants in an efficient way. As environmental concerns associated with the use of fossil fuels and increased viability of alternative technologies motivate a transition away from traditional […]

    MSE Faculty Candidate Seminar: “Atomically Thin Films and Superlattices”

    /
    Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

    Thin film materials and heterostructures play a key role in modern technology including electronics and photonics. Atomically precise engineering of thin film materials enables unprecedented control of their structure and properties, bringing exciting opportunities to materials science. Transition metal dichalcogenides (TMDs), which form three-atom-thick monolayers with van der Waals surfaces, provide an ideal material platform […]

    BE Seminar: “Immunomodulatory Biomaterials for Limb Salvage”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Diabetes and peripheral arterial disease affect hundreds of millions of people worldwide. Patients with these conditions frequently develop chronic wounds on the lower limbs that lead to amputation, with a 5-year mortality rate as high as 77%. Macrophages, the primary cell of the innate immune system, are critical regulators of angiogenesis and wound healing. Their […]

    ESE & CIS Seminar: “Toward Power-Efficient Computing with Applied Inference”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Abstract: We require computers that extract value from exponential data growth even as exponential transistor scaling falters. With limited scaling, power and thermal density threaten performance. Architects must pursue power efficiency in design and management. My research group addresses these challenges by integrating systems architecture with statistical inference. First, we design systems by tailoring hardware […]

    The Joy of Being Faculty PT I: How to Interview for a Faculty Position

    /
    Heilmeier Hall (Room 100), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    This professional development workshop series is designed to provide Penn Engineering graduate students and postdocs with a richer understanding of what it is like to pursue a career in academia from those that have navigated the process successfully. Deputy Dean Kathleen J. Stebe (SEAS) will lead this extemporaneous discussion with a panel of Penn Engineering […]

    CBE Faculty Candidate Seminar: “Facilitating Chemical Process Development Using Theoretical Modeling and Machine Learning”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Abstract: Computational modeling is an important tool to aid chemical process development. Theoretical and data-driven models can be applied both for the optimization of specific processes, and for the initial screening of potential process chemistries. I will talk about my research in advancing both of these areas. First, I will introduce the development of an […]

    MEAM Seminar: “Recent Evolution of Climate Science: From Greenhouse Gases and Temperature to Aerosol Particles and Precipitation”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    On the eve of the Intergovermental Panel on Climate Change (IPCC) Sixth Assessment Report, I will present a brief overview of how climate science has evolved since the publication of the Charney Report in 1979, and use a few examples from my recent work to show how one can use numerical models, observations and theories […]

    ESE Seminar: “Large-Scale Quantum Photonic Processors”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Abstract Photons play a central role in many areas of quantum information science, either as qubit themselves or to mediate interactions between long-lived matter based qubits. Techniques for (1) high-fidelity generation, (2) precise manipulation and (3) ultra-efficient detection of quantum states of light are therefore a prerequisite for virtually all quantum technologies. A quantum photonic […]
