Research themes: Probability, Stochastic Processes, and Analysis of (S)PDEs, with a view to solving problems from Mathematical Physics or Theoretical Computer Science.
I thank the NSF for supporting my research.

"The first to use the octopus lemma [of Caputo-Liggett-Richthammer] for something new was Chen." (G. Alon & G. Kozma, ``Comparing with Octopi'' [arXiv] [AIHPB])
Random walks, electric networks, moving particle lemma, and hydrodynamic limits (abstract, talk slides)
See this reminiscence of Tom Liggett, to appear in the Notices of the AMS. In the section on the octopus inequality written by Pietro Caputo, yours truly appears in a mention on p16 (along with Alon, Kozma, Hermon, and Salez).
Two bibles which I have studied religiously---and struggled with---for the past 5 years. They have helped my research in invaluable ways. If you are stuck interpreting passages in these bibles, I offer my translation service upon request.
