My research interests are in the general areas of mathematical biology, epidemiology, and immunology.
I have worked with students and colleagues from Texas Tech University and other academic institutions in mathematics, statistics, range, wildlife and fisheries management, biological sciences, agronomy, horticulture and entomology, microbiology, and virology, including collaborators from the TTU Health Sciences Center and the Institute for Environmental and Human Health.
Together, we have written more than ninety papers on the development and analysis of deterministic and stochastic models related to water snakes, plant pathosystems, cholla cacti, insect pests, and diseases including measles, chickenpox, chlamydia, plague, influenza, rabies, hantavirus, and chytridiomycosis.
I am actively involved in the training and advising of graduate and undergraduate students and in curriculum development in mathematical biology.
In addition, I have served as advisor for 9 PhD dissertations, 30 MS or MA theses, and 10 undergraduate research projects.
