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 StatesAbstract: 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 StatesOn 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 StatesAbstract 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 […]
CIS Seminar: Rethinking Operating System and Hardware Abstractions for Good and Evil
Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United StatesAbstract: Current hardware and operating system abstractions were conceived at a time when we had minimal security threats, scarce compute and memory resources, and limited numbers of users. These assumptions are not true today. On one hand, attacks such as Spectre and Meltdown have shown that current hardware is plagued by vulnerabilities. On the other […]
CBE Seminar: “A Case for Carbon Dioxide Removal from Air”
Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United StatesAbstract: As a global society, we have been burning fossil fuels to meet our energy and transportation needs since the start of the industrial revolution. This has resulted in atmospheric CO2 concentrations much greater than at any other time during the last 650,000 years. That concentration reached a record 415 parts per million in May […]
MSE Faculty Candidate Seminar: “Engineering non-equilibrium structure and functionality in complex solids”
Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United StatesUnique macroscopic phenomena, such as high-temperature superconductivity and colossal magnetoresistance, emerge in many complex solids due to the interplay between their electronic, magnetic, and structural degrees of freedom. This interplay also results in properties that can be tuned by manipulating their atomic structure and symmetry. In this talk, Dr. Disa will discuss two complementary “non-equilibrium” […]
ESE Seminar: “Adapting black-box machine learning methods for causal inference”
Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United StatesAbstract: I'll discuss the use of observational data to estimate the causal effect of a treatment on an outcome. This task is complicated by the presence of 'confounders' that influence both treatment and outcome, inducing observed associations that are not causal. Causal estimation is achieved by adjusting for this confounding by using observed covariate information. I'll […]
BE Seminar: “Repurposing bacterial two-component systems as sensors for synthetic biology applications “
Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United StatesTwo-component systems (TCSs) are the largest family of signal transduction pathways in biology, and a treasure trove of biosensors for engineering applications. Though present in plants and other eukaryotes, TCSs are ubiquitous in bacteria. Bacteria use TCSs to sense everything from metal ions to carbohydrates and light, and activate responses such as biofilm formation, antibiotic-resistance, […]
CIS Seminar: “User Generated Content: Opportunities to Inform Healthcare”
Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United StatesAbstract When individuals post to social media or use wearable devices, data generated through these everyday interactions with technology reveal a great deal about behaviors that influence health in ways that were previously not observable. In my work, I seek to leverage this data to characterize and measure the naturalistic manifestations a.k.a digital phenotyping of […]
