I am organizing various seminars and conferences at the moment, please see the details below.


I am currently a postdoc at UCLA under the mentorship of Raphaël Rouquier.

In Fall 2022, I will be moving to UC Berkeley as Charles B. Morrey Visiting Assistant Professor.

Prior to this, I was the Berlekamp Postdoctoral Fellow at MSRI for the Higher Categories and Categorification program in Spring 2020. I finished my PhD in 2019 at the University of Southern California under the supervision of Aaron Lauda and Sami Assaf.

Most of my work is in diagrammatic categorification and algebraic combinatorics, intersecting higher representation theory and low dimensional topology. Some of my current research directions include understanding categorical structures of vertex operators as well as the categorical and skein theoretic structures that arise in connection to Macdonald polynomials, Khovanov-Rozansky homology, and the double Dyck path algebra.

Current Organizational Activities

I am organizing an online research community on link homology at the American Institute of Math with Eugene Gorsky, Matt Hogancamp, Oscar Kivinen, and Alexei Oblomkov. Information is here.

I am currently organizing a learning seminar on categorification with Ben Elias, Mikhail Khovanov and Melissa Zhang. More information on how to participate and previous recordings of the talks can be found HERE.

I am co-organizing a conference on Algebra and QFT with Raphaël Rouquier and Noah White for Summer 2022 (?).

Some Past Events:

I am co-organized a special session at the 2021 Mathematical Congress of the Americas focused on "Categorification, Higher Representation Theory, and Homological Link Invariants" with Matt Hogancamp and Karina Batistelli on July 19-24, 2021.

I co-organized the UC Riverside Diversity and Excellence Workshop focused on Women in Combinatorics and Representation Theory alongside Vyjayanthi Chari and Zajj Daugherty on May 15-16, 2021. For more information visit the website HERE.

In Fall 2020 I co-organized the combinatorics reading seminar at UC Berkeley alongside Foster Tom and Sylvie Corteel on q,t-Catalan numbers, diagonal harmonics, and the combinatorics behind the Shuffle conjecture. For the reading schedule, notes, videos, and information click HERE.
