This is an overview of my research work organized (roughly) by topic:

1.Learning and algorithmic game theory

2.Online and stochastic optimization

3.Game dynamics

4.Signal processing and wireless communications

5.Networks, complex systems, and information theory
The above topics obviously overlap quite a bit  for a yearbyyear list of publications, go here instead.
