Hey! I’m David.

This is where you’ll find the things I do and the notes I write.

I’m a sixth-year Ph.D. student at Stanford University in the Institute for Computational and Mathematical Engineering. You’ve probably seen me if you live in the area — I’m the guy with the big hair and the ukulele. On the rare occasion that I’m not holding an impromptu uke concert, I also direct an a cappella group and perform in musical theatre productions.

I previously studied mathematics, physics, computer science, and scientific computing at Vanderbilt University. If you were a freshman in 2015, you might have known me as the guy who played guitar in the Hank House north stairwell. (I had to downsize when I flew out to Cali; couldn’t fit my guitar on the plane.)
