I'm a Courant Instructor in the NYU mathematics department, interested in analysis on metric spaces, Lipschitz mappings, and quasiconformal geometry.

I got my Ph. D. in 2014 from UCLA under the advisement of Mario Bonk.

(There is another mathematician with the same first and last name as me and some similar research interests. His page is here.)

My CV is here.

Not everyone knows what "analysis on metric spaces" means. For those who are curious, I recommend the following survey articles by Juha Heinonen:

Nonsmooth calculus, Geometric embeddings of metric spaces, Lectures on Lipschitz analysis,

and this list of questions by Juha Heinonen and Stephen Semmes:

Thirty-three yes or no questions about mappings, measures, and metrics.

For Spring 2017, I am the instructor for Section 005 of Discrete Mathematics at NYU. The course website can be found on NYU Classes.

In Fall 2016, I was the instructor for Section 008 of Linear Algebra at NYU.

In Spring 2016, I was the instructor for Section 002 of Calculus 3 at NYU.

In Fall 2015, I was the instructor for Section 003 of Analysis (Math 325) at NYU.

In Spring 2015, I was the instructor for Section 005 of Discrete Mathematics at NYU.

In Fall 2014, I was the instructor for Section 001 of Calculus 1 at NYU.

As a graduate student, I was also a teaching assistant for a number of courses at UCLA.
