I am a third year math PhD student at UCSD. My research interests are in combinatorics and probability and in particular
Extremal set theory. My advisor is Jacques Verstraete. Before I was at UCSD, I did my undergrad at UCLA and graduated in 2017.

Along with Sam Spiro, I organize the Graduate Student Combinatorics Seminar (ABACUS) at UCSD. For more info, see (here).

I am on the organizing committee for the Graduate Student Combinatorics Conference which will be hosted at UCSD in March 2020.
For more info, see (here).

Expository notes:

Through the ABACUS graduate student seminar, we have compiled the following unpolished notes on a particular topic each term at UC San Diego.


For the Winter 2020 Quarter, I will not be teaching. In the past, I have been a teaching assistant in the following courses. (n\a indicates that there were not enough evaluations submitted to release the results. This is done to protect the anonymity of the students.)

While I was in undergrad at UCLA, I served as an assistant instructor at the Los Angeles Math Circle where I worked with children from 6th to 9th grade. Read more about LAMC (here).


Outside of math, I like to run and play and watch basketball. I also currently serve as a representative for the math department
in the Graduate Student Association. For more info on this, see (here). I am also serving on the Climate Action and Policy Committee (CAP)
within the GSA which was recently featured (here).
