Cornelius Vanderbilt Professor of Biological Sciences Laurence J. Zwiebel is part of a team of researchers at Vanderbilt and the Johns Hopkins Malaria Research Institute who are working to understand how Plasmodium falciparium—the pathogen that causes malaria in humans—affects the mosquitoes that spread the disease. The research was spearheaded by Ann Carr, a current visiting scholar and former postdoctoral fellow in the Zwiebel Lab.
