Sreejith obtained his PhD in theoretical and computational study of fractional quantum Hall effects in 2012 from Penn State, USA. He was a postdoctoral fellow at the Nordic Institute for Theoretical Physics (NORDITA, Sweden) from 2012 to 2014 and at the Max Planck Institute for Complex Systems (MPIPKS, Dresden, Germany) from 2014 to 2016 before joining IISER Pune in January 2017.
Research
Condensed matter physics
Dr. Sreejith G.J. is a condensed-matter theorist working on strongly correlated quantum many-body systems and statistical mechanics, with particular interests in the fractional quantum Hall effect, quantum dynamics, and quantum spin systems. He uses computational and semi-analytical approaches, including state-of-the-art machine-learning methods. He is interested more broadly in developing algorithms for studying interacting many-body systems.
