MEAM Seminar: “Liquid Crystal Elastomers”
MEAM Seminar: “Liquid Crystal Elastomers”
Liquid crystal elastomers are rubbery solids with liquid crystal mesogens incorporated into their main chains. They display an isotropic to nematic phase transformation accompanied by a large spontaneous deformation. This in turn leads to rich variety of phenomena including ultra-soft behavior, stripe domains, shape-morphing etc. Further, when made as slender structures, the structural instability of […]

ESE Seminar: “Large-Scale Quantum Photonic Processors”
ESE Seminar: “Large-Scale Quantum Photonic Processors”
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 […]

CIS Seminar: Rethinking Operating System and Hardware Abstractions for Good and Evil
CIS Seminar: Rethinking Operating System and Hardware Abstractions for Good and Evil
Abstract: 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 […]

MSE Faculty Candidate Seminar: “Engineering non-equilibrium structure and functionality in complex solids”
MSE Faculty Candidate Seminar: “Engineering non-equilibrium structure and functionality in complex solids”
Unique 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”
ESE Seminar: “Adapting black-box machine learning methods for causal inference”
Abstract: 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 “
Two-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, […]

MSE Faculty Candidate Seminar: “Uncovering atomistic mechanisms of crystallization using Machine Learning”
MSE Faculty Candidate Seminar: “Uncovering atomistic mechanisms of crystallization using Machine Learning”
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 […]

CBE Faculty Candidate Seminar: Towards a “Greener” Route for Acetic Acid Production via the Carbonylation of Dimethyl Ether Over Small-Pore Molecular Sieves
Abstract: Catalyst design is a critical pillar, and current bottleneck, in the construction of a sustainable chemical industry. Practical catalytic materials are earth-abundant, active, selective, and stable. Developing materials that meet these criteria is challenging and involves a two-phase process that (1) extracts molecular-level understanding of the origin of reactivity for a given chemical pathway, […]
