Rishabh Dudeja

I am PhD student at the Statistics Department at Columbia University. I am fortunate to be advised by Professor Arian Maleki and Professor Daniel Hsu.
I am interested in understanding information theoretic and computational phenomena that arise in modern statistical inference problems using tools from information theory, applied probability and statistical physics.
You can find more information about me in my CV.
