I work in the Mathematics Department at Loyola Marymount University, where I serve as the Clarence J. Wallen, S.J., Chair of Mathematics. I learned about OpenWetWare from Dr. Kam Dahlquist of LMU, and I've joined to participate in Dahlquist's Lab wiki and to co-manage our course, Biomathematical Modeling (Math 388/Biol 398).

Research interests

  1. Mathematical Modeling in Biology and Ecology. I am especially interested in deterministic and stochastic approaches to modeling the dynamics of living systems. Current projects include transcriptional networks controlling environmental stress in Saccharomyces cerevisiae and energy budgets and reproductive success for Argiope trifasciata. More theoretical work is on-going in rate distribution models for understanding diversity and survival-of-the-fittest in populations.
  2. Statistical Analysis of Biological Systems under Stress. I am working with LMU biologists on various problems of detecting the response of bacteria, plants, and animals to environmental stresses, particularly heavy metal contaminants, in the Ballona Wetlands of Los Angeles.
