I am professor in the Department of Mathematics, North Carolina State University, Raleigh, NC.  My primary research experience is in the fields of biomathematics, especially, I am interested in studying the dynamics of the cardiovascular system using fluid dynamics and system level models. I have a Ph.D. in applied mathematics and a M.S. in mathematics and computer science from Roskilde University, Denmark.

Teaching Spring (2014)

MA432 - Mathematical models in life and social sciences

MA325 - Mathematical to applied mathematics
