Stephen Lewis

I am a doctoral candidate at the University of Washington studying geometric measure theory and variational problems under the supervision of Tatiana Toro. I am an RTG fellow under the NSF Inverse Problems and PDE grant. In addition to solving interesting problems, I also enjoy playing guitar, climbing, biking, and cooking.

I graduated from the University of Colorado summa cum laude in math with a minor in computer science.

Research

I study geometric measure theory, variational problems, and elliptic PDE under the guidance of Professor Tatiana Toro. I am particularly interested in singular set geometry and computational aspects of the above.
