Dr. Barbara S. Larsen, Technology Fellow, DuPont Central Research and Development, Corporate Center for Analytical Sciences, recently received the DuPont Pederson Medal. This award is named for DuPont’s 1987 Nobel Laureate, Charles J. Pederson, for his pioneering work in crown ethers. The award recognizes outstanding technological achievements and technical excellence, which has delivered value to the company.

Barbara received her B.S. in Chemistry from the University of Santa Clara, Santa Clara, CA and her Ph.D. in Physical Chemistry from the University of Delaware, Newark, DE, where she studied ion-molecule reactions using ion cyclotron resonance mass spectrometry under the guidance of Professor Douglas Ridge. She has published over 60 peer reviewed papers, numerous book chapters and three books. Barbara has served as the chair for the Delaware Valley Mass Spectrometry Discussion Group, as well as on the Board of the American Society for Mass Spectrometry as Treasurer, Vice President of Programs, and President. She has served on the editorial board for the Journal of the American Society for Mass Spectrometry, Analytical Chemistry, and is currently on the advisory board for Spectroscopy. She has received the Spectroscopist of the Year Award from the Society of Applied Spectroscopy and the American Chemical Society Delaware Section Research Award.

Barbara received the Pedersen Medal for her leadership and pioneering work in the field of mass spectrometry of polymers, surfactants and biological macromolecules.  Barbara spearheaded the development and implementation of electrospray ionization on a magnetic sector instrument prior to the commercial availability of this technique. Further, she is recognized for her application of mass spectrometry to solve complex problems, such as understanding polymer distributions, developing accurate methods for extraction and quantitation of surfactants, and creating an automated extraction method for fluorinated polymers, which is now used to demonstrate product safety and has been adopted by the U.S. Environmental Protection Agency. Barbara’s research continues to be focused on the development of sensitive ionization methods for structural elucidation of novel materials, as well as for the development of tools for systems bioanalysis as an approach to understanding and optimizing fermentation processes.
