Research Emphasis: My research is focused on the host response to the gram negative bacterial pathogens Brucella and Escherichia coli.

Immunity and Immunopathology of Brucellosis. 

Brucellosis remains one of the most common zoonotic infections world-wide with over 500,000 new human cases each year. In addition, Brucella causes disease and abortion in many agriculturally important livestock resulting in wide-spread economic losses. In humans, brucellosis can cause a chronic, multifocal infection that can lead to lifelong complications. Our lab studies several aspects of the immune response to Brucella that are important to understanding this disease, and which we feel can also serve as a means to learn more about the pathogenesis of infectious diseases in general. In particular, we are interested in determining how Brucella is able to colonize and cause inflammation in diverse tissues within the host, and investigating how Brucella is able to subvert adaptive immunity to cause chronic infection.

Pathogenesis of Bacterial Meningitis.

Neonatal meningitis causing E. coli (NMEC), is a group of E. coli that is the most common cause of meningitis in premature neonates, and the second overall most common agent of neonatal meningitis. Mortality rates from neonatal meningitis range from 10-15% in the developed world to 40-58% in developing countries. Beyond mortality, up to 50% of neonatal meningitis survivors suffer permanent neurological sequelae including deafness, seizures, hydrocephalus, cerebral palsy, and/or cognitive deficits. My laboratory is currently investigating defects in neonatal immunity that enhance susceptibility to meningitis. In addition, we are investigating immunomodulatory strategies as potential means to enhance resistance to meningitis.
