Computer Science, Art, and Mathematics: a personal journey.

I gave this talk to a group of prospective undergraduate students.  I start with a general overview of Computer Science, and then discuss how my research fits into this framework.  I then showcase my hobby of creating art from music via mathematical algorithms.  You can see more of my artwork at
