Xiudi Tang 唐修棣

In front of Malott Hall, August 2019.

I am a Postdoctoral Fellow at Department of Mathematics, University of Toronto with my mentors Yael Karshon and Marco Gualtieri after begin 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 utoronto dot ca & 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.

I am teaching MAT137: Calculus! for Fall 2019. My office is at DH 3019.

Who I am and Who I am not

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