Research Topics

Our research area is the structural biology of viruses and vaccine particles. One goal of the research is to understand the molecular organization of viruses in order to gain insights into virus assembly and function. Another goal is to study the organization of conserved viral epitopes on vaccine particles to help inform vaccine development. The research program exploits 3D electron microscopy of viruses and protein complexes with antibodies to obtain structural information on epitope disposition and conformational states. Structural analyses are supported by other structural, biochemical, and immunological analyses in order to understand immunogenicity,  antigen-antibody interactions and aid in structure-assisted design of nanoparticles for vaccines. A major focus is on the structure, assembly, and epitope display of influenza proteins and viral particles.

Biography

Dr. Harris received his Ph.D. in 2002 from The University of Alabama at Birmingham. Following postdoctoral training at the National Institute of Arthritis and Musculoskeletal and Skin Diseases, he joined the National Cancer Institute as a research fellow. In 2012, Dr. Harris was selected as an Earl Stadman Investigator and in 2013 joined the Laboratory of Infectious Diseases.
