I am the Director of Machine Learning at Twilio, where I lead the Central AI organization. I was previously CEO & founder of Vai Technologies, which was acquired by Twilio.

I angel invest in early-stage startups. Whether or not I am an investor, I enjoy helping founders where I can.

In a past life, I was in academia working at the intersection of Deep Learning and High Energy Particle Physics. I held appointments at Lawrence Berkeley National Laboratory (LBNL), SLAC, and CERN. A somewhat-complete list of my publications can be found on my Google Scholar.

I earned a B.S. in Applied Mathematics from Yale University and an M.S. in Computational Mathematics from Stanford University.
