Lance Fortnow is now Professor at Northwestern University.

Worst face photo ever. He looks like Dark Vador. Please, re-shot the pic with a better lightning, doc.

Lance Fortnow:

I study theoretical computer science, specifically computational complexity, which explores the power and limitations of efficient computation. To this end we formulate and relate many models of computation including randomness, counting, interaction, proof systems and models based on quantum mechanics and biology. A main focus of my recent research explores the effects of computationally bounded agents in a variety of economics models.
