Career Trajectory
Bio
My research is focused on strategies to control diarrhea morbidity and mortality. My research objectives are 1. finding new strategies for improved enteric vaccines and understanding vaccine immunology, 2. delineating the role of the environment in occurrence and transmission of diarrheal pathogens 3. develop new diagnostic tools for resource poor settings and better understand disease epidemiology. 4. Understanding the role of host factors in severity of disease and protection from disease. I am involved in evaluation of safety, immunogenicity and efficacy of different candidate enteric vaccines (ACE527 ETEC Vaccine, Fimbrial Tip Adhesin (CfaE) + LTR192G ETEC vaccine, Bioconjugate vaccine against Shigella flexneri 2a, Assessing Rifaximin in preventing campylobacteriosis etc). My objective in these studies is to understand the systemic and mucosal immune responses to different candidate enteric vaccines. The key focus is to find biomarkers for protective immunity using immunoproteome microarray and ELISA, role of memory B cells and T cells. My studies also involves developing and evaluating novel assays to better understand the immune responses. We also developed experimental challenge models of ETEC of Shigella in humans. These CHIM models facilitate evaluation of the efficacy of vaccines. My other research focus is epidemiology and transmission of enteric pathogens in endemic settings. In Bangladesh, my project is to understand the role of environment in transmission and outbreaks of ETEC. In Peru, we are following a birth cohort to investigate epidemiology, risk factors and protection from ETEC disease. I developed novel diagnostic assays which are simple, rapid and feasible to apply in the resource poor countries. These assays are currently under evaluation or being used in surveillance in India, Bangladesh, Zambia, Uganda and Nigeria. My research also involves understanding the role of host factors - gut microbiome, intestinal and systemic inflammation, host transcriptome and other host factors in occurrence and protection from diseases.
