Malik Younsi

I am currently an Assistant Professor (tenure-track) in the Department of Mathematics at the University of Hawaii. Previously, I was an Acting Assistant Professor in the Department of Mathematics at the University of Washington, working with Don Marshall. Before that, I spent two years as a NSERC Postdoctoral Fellow at the Department of Mathematics of Stony Brook University, working with Chris Bishop. I did my Ph.D. at Université Laval and my thesis advisor was Thomas Ransford. My main interests are in complex analysis, more precisely geometric function theory. This includes subjects such as removability, extremal problems in spaces of analytic functions (mainly analytic capacity), conformal and quasiconformal mappings, conformal welding, etc. I am also interested in holomorphic dynamics, numerical methods in complex analysis, Schramm-Loewner Evolution and potential theory.

My research is currently supported by NSF Analysis grant DMS-2050113.
