I am a third-year graduate student in mathematics at Harvard University. My advisor is Curt McMullen. Before coming to Harvard, I was a math major at University of Hong Kong.

My email address is yqzhang (at) math.harvard.edu.

## Research interests

I am currently working on hyperbolic geometry and Kleinian groups. As an undergrad, I did some summer research on Smale's mean value conjecture and finite Blaschke products under the supervision of Prof. Tuen Wai Ng. I also did my final year project on several complex variables with Prof. Ngaiming Mok, in particular, L^2 techniques in several complex variables and their applications to complex geometry.

## Current and past projects

*Constructing an acylindrical convex cocompact hyperbolic threefold with quasi-Fuchsian boundary*. Some animations illustrating the example can be found here. A paper detailing the construction can be found here. For a much shorter (and smaller in file size) excerpt focusing solely on the example see here.
*Generalized factorials on the image set of polynomials with integer coefficients*. Directed Studies in Mathematics at HKU, under the supervision of Prof. Kai Man Tsang. The final report can be found here.
*Smale's mean value conjecture and finite Blaschke products*. Summer research fellowship at Faculty of Science, HKU, under the supervision of Prof. Tuen Wai Ng. Our published paper can be found here: arxiv, journal.

## Expositions

- d-bar equations with L^2 estimates. Undergraduate final year project under the supervision of Prof. Ngaiming Mok.

## Teaching

- Spring 2018, Math 21a Multivariable Calculus, Teaching Fellow. I was awarded Certificate of Distinction in Teaching by the Derek Bok Center for Teaching and Learning at Harvard.
