Hello.
I am Hersh Singh, a postdoctoral researcher in theoretical physics at Fermilab and the Fermilab Quantum Theory Fellow. As a highenergy physicist with an interest in computation, I am excited by the developments in quantum computing and its potential in advancing our understanding of nature at a fundamental level.
Prior to joining Fermilab, I held a postdoctoral position at InQubator for Quantum Simulation at the University of Washington, Seattle and the Institute for Nuclear Theory. I obtained a Ph.D. in Physics from Duke University (20142020) working on lattice and effective field theories with Profs. Roxanne Springer and Shaliesh Chandrasekharan, and Bachelor’s and Master’s in Electrical Engineering from Indian Institute of Technology Madras (20092014), working with Prof. Suresh Govindarajan.

A complete list of my publications can be found on iNSPIRE or Google Scholar.
I thoroughly enjoy teaching and always seem to find opportunites to talk about things that I am excited about. During my PhD, I was awarded the Mary Creason Memorial Award for Undergraduate Teaching. I also taught a minicourse on Renormalization Group (Spring 2020, Duke University) for graduate students.
