Meet Our Team | Penn State College of Health and Human Development

Singh Lab's faculty, staff, and graduate students.

Principal Investigator

Vishal Singh is the principal investigator of the Nutrition and Microbiome—Singh Lab and associate professor of nutritional physiology and microbiome. Singh received his doctoral degree in Biological Sciences from CSIR-Central Drug Research Institute, Lucknow, India, in 2013 and completed his postdoctoral research training at Penn State and the University of Toledo. His recent work on dietary fibers advocates for consuming whole fruits and foods to meet dietary fiber needs and cautions against adding refined fermentable fibers to processed foods as it may increase the risk of intestinal inflammation and colon and liver cancer over time. In an intriguing study, his research shed light on a longstanding puzzle of why patients with inflammatory bowel disease report poor tolerance to certain types of dietary fibers.

Singh's research is supported by the National Institute of Health (NIH). Additionally, he serves as an associate editor for Cancer Reports, Journal of Dietary Supplements, Intestinal Microbiome, and Gastroenterology Report.
