MEAM Ph.D. Thesis Defense: “Computational Study on Rough Wall-Bounded Flows and their Effects at Low and Very-High Reynolds Numbers”
Many relevant engineering fluid dynamics problems, such as turbulent flow over an airplane or transport processes in geophysical flows, contain wall-bounded regions that form boundary layers. Oftentimes, numerical and experimental […]
PICS Colloquium: “Modeling Lone Pair Dynamics in Materials”
Materials properties are governed by the structure and dynamics of the bonds between their constituent atoms. In addition to covalent, metallic, and ionic interactions that we typically think about, lone […]
PICS Colloquium: “Genetic testing and adverse selection”
Technology is dramatically driving down the cost of sequencing genetic data and increasing the quality of predictions made with this data. A standard concern is that these predictions could impair […]
MEAM Seminar: “AI for Antibiotic Discovery”
Computers can be programmed for superhuman pattern recognition of images and text; however, their application in biology and medicine is still in its infancy. In this talk, I will discuss […]
PICS Colloquium: “Wall-models of turbulent flows via scientific multi-agent reinforcement learning”
The predictive capabilities of turbulent flow simulations, critical for aerodynamic design and weather prediction, hinge on the choice of turbulence models. The abundance of data from experiments and simulations and […]
PICS Colloquium: “Exploring the landscape of model representations”
Many studies adopt low-resolution, coarse-grained (CG) models to investigate polymers, proteins, and other soft materials. These studies must first specify the details that are retained in the low-resolution model, i.e., […]
PICS Colloquium: “An introduction to neural ODEs in scientific machine learning.”
This is a quick introduction to neural ODEs for scientific applications. The goal is to (a) provide a modelling tool that enhances the expressivity of existing theory-driven approaches, (b) demonstrate […]
PICS Colloquium: “MFEM: Accelerating Efficient Solution of PDEs at Exascale”
Upcoming exascale architectures require rethinking of the numerical algorithms used in large-scale PDE-based applications. These architectures favor algorithms, such as high-order finite elements, that expose fine-grain parallelism and maximize the […]
PICS Colloquium: “Micro-organism Locomotion in Viscoelastic Fluids”
Many microorganisms and cells function in complex (non-Newtonian) fluids, which are mixtures of different materials that exhibit both viscous and elastic stresses. For example, mammalian sperm swim through cervical mucus […]
PICS Colloquium: “Modeling Assembly of Colloids with Charges and with Mobile Binders”
In this talk, I will present our recent efforts in probing the physical processes underlying self-assembly of colloidal gels and crystals. Nano-meter to micron sized particles in suspension can be […]
