Educator, Entrepreneur, Pixelgeek

My first career was founding and building Pacific Data Images (which became PDI/DreamWorks) – it was an incredible experience.

Since then I’ve been a Venture Capitalist, serial entrepreneur, mentor and I am now an Associate Professor at Carnegie Mellon’s Entertainment Technology Center and Director of the Silicon Valley satellite campus.

I take pictures, play music and program for fun – sometimes combining all those together.

I’m an active Maker, here are some samples of recent projects I’ve done.
