Teaching


Interested in UCSC?

UCSC is a great university where to study for an undergraduate or graduate degree.  UCSC combines a wonderful campus, academically excellent degree programs, and a proximity to Silicon Valley that makes industrial collaborations, startups, exchange of ideas, and internships very easy.  If you are considering UCSC for your undergraduate or graduate studies, you might want to check where my past collaborators are now.  The strongest testament to the excellence of a program are the careers of the people who were part of it!
