Assistant Professor I enjoy working on problems in statistical machine learning and applied statistics, especially developing methods that might be of direct use to scientists (or others with large datasets). A particular interest of mine is in using convex optimization to tackle the challenges of high-dimensional datasets. |

For CVX users: Here is an R package I wrote to call CVX from R.
New: For those who prefer Julia to MATLAB (but use R primarily), I've just written convexjulia, an R package for using Convex.jl.
I enjoy juggling. Here are some videos of me club passing with the Stanford Court Jugglers. I am to the far left in this video and this video and am in the front right in this video (if you look closely, you'll notice that every pass I throw is to the person behind me).
Here's my solution to an incredible physics puzzle involving elastic collisions and the digits of pi. I wrote this up in the summer of 2010, after hearing the problem from Caitlin Stanton and Tucker Hiatt. Section 1 states the problem. My favorite part is Section 6, which gives a simple explanation for the link between having constant kinetic energy and pi.
