I am an applied mathematician and a mathematical physicist. My current research is focused on quantum computation, complexity, and information theory. I also research the generic aspects of quantum matter, which convolves random matrix theory and free probability theory with quantum many-body systems. Every once in a while I foray into classical physics, chemistry, and engineering.
I am a quantum Researcher at Google Quantum AI based in Venice beach California. From 2017-2022 I was a permanent Research Staff Member in quantum theory and algorithms group (IBM Quantum) based at Yorktown Heights, NY. I worked at theMIT-IBM AI Watson Research labin Cambridge MA, USA. From 2015-2017, I was theHerman Goldstine Fellow in mathematics at IBM Yorktown Heights. In 2012-2015 I held postdoctoral positions at MIT, Northeastern University, and University of Chicago (with Leo P. Kadanoff).
I have a blogwhich is mostly of expository nature related to my research
