David L. Popham is a professor in the Department of Biological Sciences at Virginia Tech. His research centers on bacterial peptidoglycan cell wall material, especially within endospores. Genetic and biochemical studies in his laboratory have revealed the importance of wall structural elements in spore resistance properties and germination kinetics. Current research examines the regulation of lytic enzymes required for completion of spore germination. Collaborations have examined peptidoglycan structure in numerous other bacterial species., nPopham was chair of ASM division J (Ultrastructure and Function) in 2005 and is on editorial boards for the Journal of Bacteriology (receiving the Jack Kenney Award for Outstanding Service in 2013) and Applied and Environmental Microbiology. He has served on multiple NIH study sections and on the National Research Council’s "Committee on Review of the Scientific Approaches used during the FBI's Investigation of the 2001 Bacillus anthracis Mailings".
