Other Activities

I was an officer in the Mathematics Graduate Student Association from 2008—2010. I was the MGSA appointee to the department's Computer Committee for the 2008-2009 school year. In Fall 2008 I surveyed other graduate students in the department and wrote a report outlining the status of the current computing infrastructure.

In 2008 I helped run Many Cheerful Facts, a series of weekly talks given by graduate students and aimed at a general mathematics audience.

I'm one of the delegates from the Mathematics Department to the Graduate Assembly, the graduate student government at University of California, Berkeley. I formerly chaired the Environmental Sustainability Committee and Technology Committee. I currently chair the Communications Committee.

In October 2009 I was appointed by Councilmember Jesse Arreguin (Berkeley, District 4) to the City of Berkeley Transportation Commission.
