Peter Calabrese received his undergraduate degree in mathematics from the University of Maryland, College Park; his Ph.D. in applied mathematics from Cornell University (Rick Durrett thesis advisor); and was a National Science Foundation mathematics post-doctoral fellow at the University of Southern California (Simon Tavaré sponsoring scientist). His research is in the field of computational biology, and he has collaborated with numerous molecular biology laboratories at USC.

  • Summary Statement of Research Interests

    I am interested in applying probability to problems in biology. I have worked on mathematical modeling both in terms of population genetics and stem cell dynamics. I have developed innovative computational approaches for inference from these complicated models. Perhaps more than most other computational biologists, I like to closely collaborate with biologists in terms of designing and analyzing experiments. I have also been involved with analyzing large genomic datasets. At USC, I have collaborated with the Norman Arnheim, Magnus Nordborg, Myron Goodman, Sergey Nuzhdin, Paul Marjoram, Darryl Shibata, and Simon Tavare.
