My primary teaching interest is infectious disease; a subject that is never dull. ‘New’ pathogens emerge, ‘old’ pathogens reveal their secrets, drugs are developed (closely followed by resistance), and the struggle between microorganisms and humanity goes on. My primary research interests center around the protozoan parasite, Cryptosporidium. Following a Ph.D. with a bacteriology focus, I found myself working on a European Union funded risk assessment of Cryptosporidium (a eukaryote!) in food and water. Cryptosporidium proved to be equal parts fascinating and frustrating and I wasn’t sure if I was happy or sad when the project ended. Time obviously helped me forget the frustrations because two years later, as I was setting up my lab at NDSU, I decided to make Cryptosporidium a major focus.
