I studied physics and applied math as an undergraduate in San Diego and then Computation in Neural Systems as a graduate student at Caltech. After projects with Christof Koch and David van Essen, I settled on building neuromorphic vision sensors with Carver Mead for my PhD work. After my graduate work, I went to Silicon Valley to work as a consultant on electronic imaging, first with Synaptics, and then with Arithmos, National Semiconductor and Foveon. I joined INI in 1998, together with Dr. Shih-Chii Liu. Aside from a major detour to work on the luminous tactile floor of INI's "Ada" contribution to the 2003 Swiss national exhibition, I have been working on developing neuromorphic vision sensors for real-world applications in machine vision. Together with my doctoral student Patrick Lichtsteiner, we achieved a breakthrough with the first highly functional Dynamic Vision Sensor event-based silicon retina in 2006. Since then, the Sensors group has been evolving this technology and exploring its manifold applications in event-driven vision. Our most recent breakthrough is our flagship sensor called DAVIS. In my spare time, I also really enjoy reading and like to play tennis and basketball. I like riding my bike to work and sometimes I practice some card magic and I even rejoined the Magic Castle in Hollywood recently. For holidays we often travel back to our home in Pasadena where I grew up as a faculty child.
