The mission of the Institute for Human Infections and Immunity is to coordinate, facilitate and enhance the activities of UTMB's research centers and programs that focus on advancing the fields of infection and immunity. It is to understand the nature of infectious diseases, and work to translate new research concepts into products aimed at controlling emerging infectious diseases and mitigating their effects on society. The programs of the Institute for Human Infections and Immunity (IHII) are the hub of infectious disease research at UTMB.

IHII programs include the Galveston National Laboratory, the Center for Biodefense & Emerging Infectious Diseases, the WHO Collaborating Center for Tropical Diseases, the Sealy Center for Vaccine Development, the World Reference Center for Emerging Viruses and Arboviruses and the McLaughlin Endowment for Infection and Immunity.

Research Interests

My research focuses on arboviruses, including mechanisms of emergence from enzootic cycles, evolution, mosquito-virus interactions, and vaccine development. My research approaches include reverse genetics to identify adaptive mutations that mediate host range changes, and field studies in Africa and Latin America to understand the ecology and epidemiology of emerging arboviruses.
