I’m Kathryn, a fourth-year Ph.D. candidate studying shape from shading and TDA with Prof. Todd Zickler. I have been working toward a doctoral degree in Applied Mathematics (AM) at Harvard SEAS as a Draper Laboratory Fellow since September 2014. I graduated from Harvard with a MS in AM in November 2016, and from UCLA with a BS in AM in June 2014.


The homotopy extension property.


Recent travel:

  • S3PM (Shape, Solid, Structure & Physical Modeling) at UC Berkeley, June 2017. Received a NSF student travel award.
  • ISIT (Information Theory) at RWTH Aachen University in Germany, June 2017, giving a talk titled The Number of Independent Sets in Hexagonal GraphsSlides from my talk.
  • SIAM-AG (Algebraic Geometry) at Georgia Tech, July 2017, presenting a poster titled Induced Probability Measures on Persistence Diagrams. My poster.File_000 (1).jpeg



My research sits at the intersection of statistics, geometry, and topology.

Programming languages: I prefer Python (notebooks) and MATLAB, but also have experience with C++, Java, and HTML/CSS. In addition, I am familiar with Mathematica and LaTeX, and a little bit of Magma. I also enjoy making mathematical figures in Adobe Illustrator — for example, those on this page!

Teaching experience: I was a teaching fellow ENGSCI 150 (Introduction to Probability for Engineers) at Harvard in Spring of 2015. I am honored to have received a Certificate of Excellence in Teaching, based on student evaluations.




You may notice some diversity in my work — I wear a lot of hats!
