Alex Anderson

Hello! My name is Alex and I am a deep learning research scientist at WaveOne. I worked with Bruno Olshausen in the Redwood Center for Theoretical Neuroscience during my Ph.D. In the summer of 2016, I interned at Oculus Research. In the past, I graduated summa cum laude at Washington University in St. Louis with a double major in math and physics. I did my undergraduate thesis with Carl Bender. Before that, I enjoyed high school math competitions.
