Between 2011 and 2016, I was a grad student at the CUNY Graduate Center, during which time I was an adjunct at the Bronx Community College, Brooklyn College, Hunter College, and Vassar College.
Between 2016 and 2020, I was an itinerant postdoc/contingent worker at the Max Planck Institute, IISER Pune, Oberwolfach, Xiamen University Malaysia, Smith College, and the University of British Columbia. I've also worked at the Go Project, BEAM, and Bard Microcollege.
Since 2020, I've been here!

I mainly work in number theory and representation theory. I love to collaborate, so please reach out!
