Hello.
I am Hersh Singh, a postdoctoral researcher in theoretical physics at the InQubator for Quantum Simulation at the University of Washington, Seattle. I am also affiliated with the Institute for Nuclear Theory.
I am interested in studies of strongly coupled quantum field theories, with applications to nuclear and highenergy physics, using the powerful tools of lattice field theory, effective field theory and quantum information science.
Before this, I got a
 PhD 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.
Some of my recent work includes
 qubit regularizations of quantum field theories: with the goal of constructing regularizations of interesting QFTs for the quantum simulation of QFTs
 application of nuclear effective field theory: largeN expansion in twobody systems, and threebody systems
 many of my ongoing projects are around using study aspects of quantum information in QFTs, using worm algorithms and tensor network methods
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.
