Rick Yost was born in Ohio, and lived his first seven years in West Virginia, before his family moved to Arizona. His B.S. degree in Chemistry was received from the University of Arizona (opens in new tab) in December 1974. His interest in analytical chemistry was kindled by Professors Quintus Fernando and Bonner Denton in courses in Quantitative Analysis and Instrumental Analysis, and by Professor Mike Burke and graduate student John Phillips in analytical research involving computer simulation of gas chromatography. Summer jobs at Affiliated Pathologists Laboratories, Motorola Semiconductors, and the University Analytical Center exposed him to a wide range of applications of analytical chemistry.
In January 1975, Rick moved from Arizona to the frigid north to pursue graduate studies in analytical chemistry under an NSF graduate fellowship at Michigan State University (opens in new tab), focusing on electronics and computerized instrumentation. Together with Professor Chris Enke (opens in new tab), he conceived of the computerized tandem quadrupole mass spectrometer for analytical MS/MS studies. Although their proposal to NSF was not persuasive enough to convince the reviewers that such an instrument was viable or analytically useful, Dave Nelson of the Office of Naval Research (opens in new tab) invested in the proposed research. A couple thousand pounds of stainless steel, aluminum, and electronics later, the instrument was taking form, when a chance meeting at the May 1977 ASMS Conference in Washington, DC, with Professor Jim Morrison (opens in new tab) of Australia’s LaTrobe University (opens in new tab) found unexpected support. Jim had constructed a similar triple quad instrument for laser spectroscopy of mass-selected ions and invited Rick to spend a couple of months performing preliminary experiments on that instrument. Those experiments, combined with computer simulations of ion trajectories with SIMION (opens in new tab) (written by Jim and his graduate student Don McGilvery) were instrumental in the successful completion of the Michigan State instrument. The instrument was patented (opens in new tab) by Research Corporation for MSU.
Rick received his Ph.D. in the summer of 1979 and assumed the position of Assistant Professor at the University of Florida. Rick has risen through the ranks at UF to Professor and Head of the Analytical Chemistry Division. His has supervised over 120 graduate students (opens in new tab) over the past 43 years, graduating over 100 PhDs. He has served as PI or Co-PI on grants and contracts totaling over $65M of funding. Research in his group has led to over 240 publications (opens in new tab) and 16 patents. Also contributing to these research efforts have been a number of collaborators at UF and around the world, visiting scientists, plus undergraduate and high school researchers. His research emphasis for the past few years has been the development and application of innovative mass spectrometric methodologies, including imaging mass spectrometry and ion mobility, for global and targeted metabolomics, lipidomics, and clinical analysis.
The triple quadrupole mass spectrometer that he invented is the most common mass spectrometer in the world today, with sales of over $1 billion per year! Other pioneering instruments from his lab that are now widely used as commercial systems include the ion trap tandem mass spectrometer and the laser microprobe tandem mass spectrometer. Dr. Yost’s research has been recognized with the highest award in his discipline, the ASMS Award for Distinguished Contribution in Mass Spectrometry (opens in new tab) as well as the 2018 MSACL Award for Distinguished Contribution to Clinical Mass Spectrometry (opens in new tab), the 2019 CPSA Distinguished Analytical Scientist Award (opens in new tab), the 2019 Florida Academy of Sciences Medal (opens in new tab), and the 2021 Pittsburgh Analytical Chemistry Award (opens in new tab). He was awarded the National Distinguished Eagle Scout Award (opens in new tab) in 2019. In recognition of his inventions, he was inducted into the Florida Inventors Hall of Fame (opens in new tab) in 2019 and named a Fellow of the National Academy of Inventors (opens in new tab) in 2021.
Dr. Yost recently completed terms on the Florida Board of Governors (opens in new tab) (Regents) and the University of Florida Board of Trustees (opens in new tab). He is serving a six-year term first as Vice President for Programs, then President, and now Past President of ASMS (opens in new tab) (the American Society for Mass Spectrometry). He also serves as Director of the Southeast Center for Integrated Metabolomics (SECIM (opens in new tab)) as well as Director of the NIH Metabolomics Consortium Coordinating Center (M3C (opens in new tab)).
On the personal side, Rick married Katie Fitzgerald a week after his Ph.D. commencement in 1979. As best friends and partners in life, we have enjoyed traveling around the world and raising a wonderful family – Sarah (BS in Biology from Furman University), Mike (BS in Environmental Sciences from Florida Institute of Technology) and Matt (BS in Anthropology from UF).
