    • CBE Doctoral Dissertation Defense: “Quantitative Transcriptional Regulation through Protein–DNA Interactions in Developing Systems” (Gaochen Jin)

    /
    Towne 225

    Abstract: Precise regulation of gene expression is essential for controlling developmental programs, maintaining cellular identity, and ensuring proper tissue function. Dynamic interactions between proteins and cis-regulatory elements integrate molecular mechanisms and extracellular signaling to achieve precise control of transcriptional activity. In this thesis, I investigate protein-DNA-mediated transcriptional regulation across two distinct developmental systems: mouse embryonic […]

    MEAM Seminar: “Predicting Infant Center of Pressure through Physics and Data Driven Modeling”

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

    Affecting roughly 2 in 1000 infants in the USA, Cerebral Palsy (CP) is the most common cause of motor impairment in children. CP has no cure, but motor therapy is an effective tool for providing rehabilitation. Although therapy is most effective before the age of 2, early CP detection is difficult and labor-intensive, making the […]

    MEAM Seminar: “Temperature Dependent Offset for Spin Lattice Dynamics Modeling”

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

    Spin lattice dynamics (SLD) modeling is an approach to modeling magnetic interactions at the nanoscale. Current spin lattice dynamics models do not model magnetoelastic effects well, giving non-physical lattice parameters and poorly modeling behavior like forced volume magnetostriction. A new model, based on a temperature dependent offset that subtracts out the part of the magnetic […]

    AI + Science Seminar

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Extracting Knowledge Priors from Scientific Texts for De Novo Molecular Design This talk will explore a large-scale effort to exploit the natural-language understanding capabilities of large language models in order to unlock information about the structure, function, and biological activity for proteins, small molecules, genetic variants, and other biological entities of interest.

    ASSET Seminar: “AIRFoundry: AI for RNA Discovery and Synthesis”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Virtually everyone today is aware of the mRNA vaccine for COVID, which saved many lives and earned the Nobel Prize for Drs. Drew Weissman and Katalin Kariko. The vaccine consisted not only of mRNA that coded for the COVID spike protein, but a protective lipid nanoparticle envelope that carried the RNA to cells in the […]

    CBE Doctoral Dissertation Defense: “Silica Nanoparticle-Based Platform for Rare Earth Element Recovery and Separation” (Ivy Dai)

    /
    Vagelos Institute for Energy Science and Technology, Room 121 231 S 34th Street, Philadelphia, PA, United States

    Abstract: Rare earth elements (REEs) are essential for clean energy technologies including batteries for electrical vehicles, wind turbines and LED screens due to their unique magnetic, optical, and electronic properties. Efficient methods for their recovery and separation are urgently needed to meet the growing demands of a rapidly evolving green economy worldwide. However, current separation […]

    • MEAM Seminar: “Harnessing Living Bacteria, Fungi, and Plants as Functional Materials”

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

    For decades materials engineers have been inspired by biology to create improved properties, for example nacre-inspired hierarchical structures to improve toughness, tree-inspired vasculature to deliver fluids that can react and heal an interface, and mussel-inspired strong underwater adhesives utilizing cation-pi interactions. Now, the bioengineering toolset has reached a maturity where we can start to employ […]

    Penn AI Seminar Series: Geometric and Physics Stucture Preservation in Scientific Machine Learning

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Geometric and Physics Stucture Preservation in Scientific Machine Learning Nat Trask, Associate Professor in Mechanical Engineering and Applied Mechanics at Penn Engineering, will share about his work constructing real-time digital twins built upon a data-driven finite element exterior calculus; constructing auto-regressive integrators with guaranteed long-term stability independent of rollout length; and constructing data-driven particle models […]

    ASSET Seminar: “Provable vs Impossible Trust: Reasoning, Steering, and Safety”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Abstract: In this talk, I will discuss a collection of highlights from our recent work in trustworthy AI. (1) Certifying reasoning explanations with reliability guarantees and aligning with expert knowledge, (2) Simple yet effective steering inspired from theoretical rule-following mechanisms for transformers, and (3) The impossibility of monitoring stateless attackers and what safety defenses should […]

    CBE Seminar: “Water–Hydrophobe Interfaces: From Debunking Myths to Boosting Global Food–Water–Climate Resilience” (Himanshu Mishra, KAUST)

    /
    Wu & Chen Auditorium

    Abstract: First, I will outline our work on overcoming barriers to desert rehabilitation for urban greening, landscaping, and regional food security. In arid regions, freshwater is scarce, sandy soils lose water and fertilizers rapidly, which stifles plant growth. Our team has developed two complementary solutions: (i) Superhydrophobic Sand (SHS)1 — a plastic-free, bio-inspired mulch that […]

    FOLDS Seminar: Positive random walks and positive-semidefinite random matrices

    /
    Amy Gutmann Hall, Room 306 3317 Chestnut Street, Philadelphia, PA, United States

    On the real line, a random walk that can only move in the positive direction is very unlikely to remain close to its starting point. After a fixed number of steps, the left tail has a Gaussian profile, under minimal assumptions. Remarkably, the same phenomenon occurs when we consider a positive random walk on the […]
