About

Hello! My name is Saibal De, and I am a 4th year PhD student at the Department of Mathematics, University of Michigan. My advisors are Prof. Shravan Veerapaneni and Prof. Xun Huan.

I am interested in developing algorithms for physics based simulations of granular media and particulate flows. I use high performance computing frameworks and fast algorithms to resolve contact between the particles, and boundary integral methods for modeling fluid-particle interactions. Recently, I have started working on data-driven modeling using tensor decompositions.

I obtained my Four Year Bachelor of Science (Research) degree in Mathematics (with a minor in Physics) from Indian Institute of Science (Bangalore) in 2016.

I currently co-organize the Directed Reading Program at the Departhemt of Mathematics, University of Michigan. During Fall 2018 and Winter 2019 semesters, I co-hosted the Student Machine Learning Seminar with Rishi Sonthalia.
