About me

I am an Assistant Professor in the Department of Applied and Computational Mathematics and Statistics (ACMS) at the University of Notre Dame, IN, USA.

I am currently looking for a prospective Ph.D. student to work on theory and applications of Machine Learning and Computational Imaging. Interested individuals are requested to reach out to me over email at soham-dot-jana-at-nd-dot-edu.
