Biography and Research Information

OverviewAI-generated summary

Sangeeta Khare, a Research Microbiologist at the National Center for Toxicological Research, investigates the impact of various substances and exposures on biological systems, with a particular focus on the gastrointestinal tract and its microbiome. Her work utilizes in vitro models, including polarized intestinal epithelial cells and continuous flow bioreactors, to assess cellular responses and alterations to microbial communities. Recent research has examined the effects of co-exposure to pesticides and nanoparticles, the influence of chronic tetracycline exposure on the human intestinal microbiota, and the impact of pristine graphene on colon tissue gene expression.

Further investigations by Khare explore the relationship between environmental exposures and health outcomes. This includes studies on how routes of arsenic exposure differentially affect immune responses and gut permeability, and the development of preclinical in vitro models to evaluate changes in intestinal epithelial cell permeability and cytotoxicity. Her research also extends to understanding the conformational changes of viral proteins, such as the SARS-CoV-2 spike protein, and predicting antigenic epitopes. Khare's scholarship metrics include an h-index of 28, with 118 total publications and 8,709 total citations, designating her as a highly cited researcher. She collaborates extensively with colleagues at the National Center for Toxicological Research, including Kuppan Gokulan, Chandra Mohan Reddy Muthumula, Yaswanthi Yanamadala, and Kumari Karn.
