I develop quantitative models & algorithms that emulate the behavior of human experts. In particular, I specialize in developing interpretable models that combine mathematical theory with human intuition. LinkedIn Instagram

Currently: I'm developing the models & algorithms that drive Math Academy's fully automated and personalized online learning system. Like any sport, learning math is all about 1) completing training exercises in a scaffolded sequence, 2) doing them often enough that you don't get out of shape, and 3) having enough fun to keep you motivated. So, we're creating a granular network of high-quality lessons, serving those lessons (and reviews) to students at the appropriate times, and making the learning experience as enjoyable as possible. Our curriculum extends from prealgebra all the way through university-level math.

Background: I earned a BS in Mathematics from Notre Dame on full-ride scholarship, and a MS in Computer Science (Machine Learning track) from Georgia Tech, all while working full time. I've done plenty of interesting things with math, including building predictive models for businesses as a data scientist, simulating and proving properties of biological neural networks, and completing two particle physics research projects that improved CERN and Fermilab particle detectors. I also tutored & taught math for nearly a decade, culminating in (currently) developing and teaching one of the most advanced high school applied math/CS sequences in the world, Math Academy's Eurisko sequence.

  • Music. I taught myself guitar in grade school and still pick it up every once in a while. I learned viola too, but haven't kept it up since high school. During college, I spent a bit of time on music production. I listen to music all the time while working, and have lately been listening to a lot of Ava Max and Shuba.
  • Writing. I've written several textbooks for fun as a way to consolidate and clarify my quantitative intuition.
  • Fitness. I played hockey and did a bunch of weightlifting/bodybuilding in high school, then stopped, and have recently gotten back into shape with gymnastic rings and parallel bars.
