A Transformative Co-Design Approach to Materials and Computer Architecture Research (Threadwork)

Co-design approach that encompasses neuromorphic computing, systems architecture, and datacentric applications. Focus on high energy physics (HEP) and nuclear physics (NP) detector experiments

CETOP - A Center for Edge of Tokamak OPtimization

The project overarching objective is to develop the simulation capability and to perform extended MHD and (drift-gyro) kinetic simulations of non-ELMing (and some ELMing) regime operating points to close gaps in understanding, prediction, and optimization of edge stability for an FPP. I am leading a team to develop ML techniques for extracting reduced-order models, data reduction, and feature extraction to the existing non-ELM database (based on interpolation of data), and to extrapolate to new parameter regimes (such as coil currents for negative-triangularity shaping) for ELM-free optimization.

Enabling Cosmic Discoveries in the Exascale Era

The overarching objective of this SciDAC-5 project is to create consistent predictions of the dark and visible Universe across redshifts, length scales and wavebands based on state-of-the-art cosmological simulations. The simulation suite will encompass large-volume, high-resolution gravity-only simulations and hydrodynamical simulations equipped with a comprehensive set of subgrid models covering both small and large volumes. The simulations will be coupled to a powerful analysis framework and associated tools to maximize the analysis flexibility and science return.

Foundations for Correctness Checkability and Performance Predictability of Systems at Scale (ScaleSTUDS)

Multi-dimensional automated scalability tests, program analysis, performance learning and prediction at various levels of the software/hardware stack.

ML Assisted Equilibrium Reconstruction for Tokamak Experiments and Burning Plasmas
