Optimization Algorithms and (more recently) Algorithmic Game Theory; see my (soon to be updated) CV for more details.
I graduated with my PhD in Computer Science at the Donald Bren School of Information and Computer Sciences, UCI. I was a member of the theory group at UCI; my advisor was Sandy Irani. After spending some time at Tata Research Development and Design Centre, an industrial research lab, I am back in academia as a research fellow at Nanyang Technological University (details above).
The best way to reach me is via email: jea at ics dot uci dot edu. (Yes, I still use my UCI email.) Here's my LinkedIn.com profile.
