Academic History

I graduated from the University of Utah with a Ph.D. in Mathematics in 2003. I was a Pfeiffer-VIGRE Instructor at Rice University until 2006. I was a Research Associate at the Laboratory of Biological Modeling at NIH until 2008 when I became an Assistant Professor at UMBC. I am currently a Professor in the Mathematics and Statistics Department at UMBC.

Research Interest

My research focus is on using mathematical techniques and modeling to solve biological (typically physiological) problems.
