Prior to that I've worked on Google Photos, Google Brain, and at a startup building a hearing aid. My academic background is in astronomy where I worked on the dynamics of few-body systems. Sometimes I write about astronomy, machine learning, or other things here:

I did a podcast for a few years about the history of astronomy which you can listen to here: https://songofurania.com/
