Marcel Hudiani

About Me

I am a Kempe Postdoctoral Fellow at Umeå University in Sweden working with Prof. Sebastian Throm. I got my Ph.D in Mathematics at the University of Arizona under Prof. Sunder Sethuraman. I was a product engineer and pre-silicon validation engineer at Intel Corporation from 2011 to 2016. I received my M.S.E in Electrical Engineering from Arizona State in 2012 and B.Sc in Mathematics from the University of Arizona in 2021. I work in the area of stochastic processes, particle systems, and their connections/applications to other fields, including (stochastic or deterministic) partial differential equations and artificial intelligence. I am also interested in numerical simulations of these particle systems, especially with singular coefficients.
