Dr. Yost is the Colonel Allen R. and Margaret G. Crow Professor and Head of Analytical Chemistry at the University of Florida. He is recognized internationally as a leader in the field of analytical chemistry, particularly tandem mass spectrometry (MS/MS). He may be best known for inventing (as a graduate student with Chris Enke at Michigan State University) the triple quadrupole mass spectrometer, which 40 years later represents over $1B in sales each year. Dr. Yost's professional activities have focused on research and teaching in analytical mass spectrometry, particularly tandem mass spectrometry (MS/MS). His group's research has reflected a unique balance between instrumentation development, fundamental studies, and applications in analytical chemistry. His group has led in the application of novel mass spectrometric methods and techniques to areas such as metabolomics, clinical, biomedical, pharmaceutical, environmental, and forensic chemistry. Dr. Yost has supervised the research of well over 100 graduate students during the past 37 years, graduating over 85 PhDs from his group. He has served as PI or Co‐PI on grants and contracts totaling over $50M of funding. Research in the group has led to almost 200 publications and 16 patents. He still loves teaching undergraduates and graduates in the classroom each semester. Dr. Yost recently completed terms on the Florida Board of Governors (Regents) and the University of Florida Board of Trustees. He is director of the NIH‐funded Southeast Center for Integrated Metabolomics. He is also a Professor of Pathology at the University of Florida. His research has been recognized with the highest award in his discipline, the 1993 ASMS Award for Distinguished Contribution in Mass Spectrometry, as well as the 2018 MSACL Award for Distinguished Contribution in Clinical Mass Spectrometry. He currently serves as the VP for Programs of ASMS, and will become President in July.
