Dr. Chen is an adult infectious disease physician, clinical vaccinologist, Chief of the Adult Clinical Studies section at the CVD, and Director of the UMB Travelers’ Health Clinic. His primary research interests are twofold: developing vaccines for the elderly (a rapidly growing segment of the global population which is susceptible to infection) and developing vaccines for enteric pathogens (diseases chiefly of developing countries). He has been the principal investigator on vaccine trials for: influenza (Seasonal, Pandemic 2009 H1N1, and Avian H5N1 influenza), agents of bioterror (Tularemia and Staphylococcal enterotoxin B), and enteric pathogens (enterotoxigenic E. coli and cholera). He also has a basic laboratory research program that uses murine models of pneumonia to study the innate immune response and candidate therapeutics.
