I am Moore-Sloan Research Fellow at the Center for Data Science at New York University. I also have a Collaboration Scientist appointment at the Algorithms and Geometry Simons Collaboration.
Before this I was a Research Fellow at a semester-long optimization program at the Simons Institute, UC Berkeley.
On May 2017 I finished my PhD in Mathematics at the University of Texas at Austin, I was very fortunate to have Rachel Ward as my advisor.
My research is in mathematical data science and optimization. I am also interested in number theory. (Here is my CV.)

I also enjoy coding. I write about my projects in my Blog. Below is my favorite so far (Clustering the MNIST data set using semidefinite programming).
