My real name: Daniel O'Connor.
I'm an assistant professor in the Mathematics and Statistics department at University of San Francisco.
Background: Applied math PhD at UCLA, researched algorithms for large scale convex optimization with advisor Lieven Vandenberghe. I did a postdoc in the UCLA Department of Radiation Oncology, where I developed algorithms for radiation treatment planning.
Here's my PhD thesis: http://escholarship.org/uc/item/4z1126w3#page-1
