Homepage of Joydeep Chowdhury

I am a researcher in Statistics. I received my PhD from Indian Statistical Institute, Kolkata. My PhD supervisor was Prof. Probal Chaudhuri. My current research interests include statistical methods in high dimensional and infinite dimensional data, nonparametric inference and regression, quantile and statistical depth based methods, convergence rates of nonparametric estimates in infinite dimensional spaces, etc.

I am a postdoctoral fellow in King Abdullah University of Science and Technology since September, 2020. My mentor is Prof. Marc Genton.

My thesis can be found here.

My Curriculum Vitae is here.
