Brief Profile

Dr. Vakdevi Validandi, Ph.D in Biochemistry, joined as scientist-B in 2012. Her research area of interests is mycotoxin research. She is trying to develop and validate the HPLC/LCMS MS methods for the estimation of aflatoxin B1 biomarker (Aflatoxin B1-lysine adduct) in the serum samples. She is working on the mycotoxin contamination levels in the various commonly consumed food items and herbal medicines and assess the human health risk associated with the consumption of mycotoxin contaminated foods.
