Brief Profile

Dr. VakdeviValidandi, Ph.D in Biochemistry, joined as scientist-B in 2012. Her area of interest is ‘Molecular aspects of fluorosis’. Her research is trying to understand the molecular mechanism involved in the enhanced urinary excretion of fluoride in the tamarind supplemented rats and to understand the biochemical and molecular mechanism of insulin signaling in fluoride induced insulin resistance in rats.
