I also work on wide-field radio surveys with next generation radio telescopes, searching for transient and variable radio sources as well as the signatures of supermassive black hole binaries and mergers. I am an associate member of the Murchison Widefield Array and NANOGrav collaborations, and an advisor to the Square Kilometer Array Transient Science Working group. I'm also interested in how supermassive black holes interact with their environments, including through spectacular examples of feedback such as Minkowski's Object.
I helped conceive and implement the NOVAS high school program combining art and the maker movement with astronomy education. In 2009 I founded, and continue to run, the Science@Cal Lecture Series, a series of free lectures that welcomes 100 - 150 members of the public to campus each month to hear about research taking place at UC Berkeley. I have written material for the UC Museum of Paleontology's Understanding Evolution website, and for the Big History Project.
