I just finished my PhD in Mathematics at the University of Texas at Austin, I was very fortunate to have Rachel Ward as my advisor. Now 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.
My research is in mathematical data science and optimization. I am also interested in number theory. (Here is my CV.)

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

Check out my blog at solevillar.github.io.
