Dr. Yang Lan  兰洋

I am currently a tenure track assistant professor at Yau Mathematical Sciences Center, Tsinghua University. Before that, I was a postdoc at Department of Mathematics and Computer Science in University of Basel. My mentor there was Prof. Enno Lenzmann. I obtained my Ph.D. in mathematics from Université Paris-Sud XI, under the supervision of Prof. Frank Merle and Prof. Thomas Duyckaerts. My research interests are on partial differential equations, analysis and mathematical physics.
