Senior biochemistry major David Willen spent his capstone last summer at the University of Maryland School of Medicine’s Institute for Human Virology in the Laboratory of Viral Diagnostics, under the guidance of Dr. Neil Constantine. His work involved testing the sensitivity of HIV rapid testing kits. These kits are essential in rural and underdeveloped areas to quickly diagnose HIV positive patients and prevent the spread of disease. David presented his work at the 21st Annual International IHV Conference held in downtown Baltimore last week.
