Visiting Scientist

U.S. Food & Drug Administration

Dr. Sanghamitra Majumdar is a Staff Fellow at the U.S. FDA National Center for Toxicological Research. She is actively engaged in closing the technical gaps by characterizing the quality attributes of nano-enabled medical products and developing international consensus standards to provide guidance to regulatory agencies and industry. Dr. Majumdar’s primary research interest lies in exploring the scope and challenges towards the safe and sustainable use of engineered nanomaterials in medicine, food, and agriculture.She is recognized for her pioneering contributions in advancing the field of analytical science with major focus on characterizing nanomaterial exposure and novel methods of detection of sensitive biological response. She has expertise in nanomaterial characterization, toxicity and biochemical assays, proteomics, metabolomics, and quantitation of inorganic and organic (small and large molecules) species in environmental and biological samples using mass-spectrometry-based analytical techniques. 

Dr. Majumdar received her PhD in Chemistry from the University of Texas at El Paso in 2014. She worked as a postdoctoral agricultural research scientist at the Connecticut Agricultural Experiment Station (CAES) with Dr. Jason C. White. She was also a postdoctoral research scientist at the University of California, Santa Barbara, BREN School of Environmental Science and Management with Dr. Arturo A. Keller. 

She serves as a member on the American Society for Testing and Materials (ASTM) Committee E56 on Nanotechnology, US FDA Standards Subcommittee, and the US FDA Center for Drug Evaluation and Research Nanotechnology Reviewers Network. Dr. Majumdar has co-authored over 25 peer-reviewed articles and has delivered over 30 presentations in national and international scientific meetings. She serves on the editorial board of Agronomy and Agricultural Biological Chemistry- Frontiers in Chemistry.
