I am a postdoc at University of Luxembourg since September 2023, under the supervision of Karin Melnick.
I am on the job market as of August 2026.
I received my PhD in Math in May 2023, from The Ohio State University where my thesis advisor was Andrey Gogolev.
My name in simplified Chinese: 张丹彧.
Research
I am broadly interested in questions with a flavor of understanding the underlying topology and / or geometry of the spaces with the presence of dynamics (or maybe vice versa), though it might appear that I study smooth dynamics with hyperbolicity.
More specifically, I am currently thinking about (in order): centralizers of fibrewise Anosov diffeos, some math physics (very new to me) with Jing, Anosov flows in higher dimensions, (topological) classification of Anosov diffeos (as always)…
