About me:

I am an RTG Postdoc at the University of Minnesota. Before coming to UMN, I was a postdoc at Indiana University- Purdue University, Indianapolis. I got my Ph.D from the University of Michigan in 2016, where my advisor was Sergey Fomin.


I am organizing the UMN Combinatorics Seminar this year with Vic Reiner; contact us if you would like to give a talk.

UMN will host an "Open Problems in Algebraic Combinatorics" conference in May 2020.


Research interests:

Algebraic combinatorics and representation theory, especially cluster algebras and total positivity.

My CV is available here.


Papers and preprints:

1. Quantum affine algebras and Grassmannians (with Wen Chang, Bing Duan, Jianrong Li) , arXiv preprint (2019) .

2. Tropicalization of positive Grassmannians (with Ian Le), arXiv preprint (2017), submitted.

3. From dimers to webs (with Thomas Lam and Ian Le). Transactions of the American Mathematical Society (2019).

4. Braid group symmetries of Grassmannian cluster algebras. arXiv prepint (2018), submitted. Accompanied by SAGE code.

5. Quasi-homomorphisms of cluster algebras. Advances in Applied Math no. 81, 2016.
