I joined the DAS group (Data & Analytics Services) at NERSC as a Postdoctoral Scholar in April 2018.

My responsibilities include:

  • Assisting High Energy Physics groups LZ and ATLAS in running their computation on NERSC machines.
  • Developing computational workflows for High Energy Physics computations.
  • Using Machine Learning to solve problems in High Energy Physics.

Background:

My research background is in Theoretical and Computational Particle Physics. I got my PhD in Theoretical Physics from Duke University in September 2016, specializing in Lattice Field theory. As a postdoc at the University of Colorado at Boulder, I worked on the study of lattice gauge theories of interest in Beyond Standard Model Physics. During this time, I also worked on developing Databases and computational workflows for lattice gauge theory calculations.

Research Interests:

Machine Learning, Scientific workflows, Databases, Lattice gauge theories.
