Ana Paula Alonso, PhD. obtained her B.S., M.S., and Ph.D in Biological and Medical Sciences from the Université Victor Segalen in Bordeaux, France. After four years of postdoctoral training in seed metabolism (Michigan State University), and microbial metabolism (Institut National des Sciences Appliquées, Toulouse, France), she joined the Great Lakes Bioenergy Research Center in 2008 as a Visiting Assistant Professor to work in the exciting field of biofuel research. In 2010, Dr. Alonso accepted a position as an Assistant Professor in the Department of Molecular Genetics at The Ohio State University where she was the Director of the Targeted Metabolomics Laboratory; she was promoted to Associate Professor in 2016. Dr. Alonso joined the BioDiscovery Institute at the University of North Texas in 2018 and most recently appointed Interim Director of the BioDiscovery Institute; she is a Professor in the Department of Biological Sciences and the director of the BioAnalytical Facility.
