Xiudi Tang 唐修棣

In front of Malott Hall, August 2019.

I am an Assistant Professor at School of Mathematics and Statistics, Beijing Institute of Technology. My office is at 901C, Liberal Arts Building II.

I was a Postdoctoral Fellow at Department of Mathematics, University of Toronto with my mentors Yael Karshon and Marco Gualtieri after being a Visiting Assistant Professor at Cornell University with my mentor Reyer Sjamaar. I received my PhD in mathematics at University of California San Diego supervised by Álvaro Pelayo in 2018 and a BS in mathematics from Tsinghua University in 2014.

My email addresses are xiudi dot tang at bit dot edu dot cn & xdtang dot math at gmail dot com. Take a look at my CV and find the preprints of most of my articles on my arXiv profile.

Who I am and Who I am not

I am a thinking human being.
I am not a working machine.
