Ben Bythell

Professor Bythell received his MChem. degree from the University of Bath, UK, in 2002 and Ph.D. from Oregon State University in 2007. He held postdoctoral fellowships at the German Cancer Research Center in Heidelberg (2008-2010) and at the National High Magnetic Field Laboratory at Florida State University (2010-2013). He joined the faculty in the fall of 2013.

Research Interests

Dr. Bythell works at the interface between analytical, computational and biophysical chemistry where he strives to understand the structure, reactivity and gas-phase behavior of biologically- and industrially important chemicals. Fundamentally, chemical structure determines the properties and potential functions of any given molecule. Consequently, the gas-phase structures occupied by an analyte ion have direct influence on which fragmentation pathways are populated, and thus, on the resulting mass spectrum. The ability to decipher both the elemental composition (CcHhNnOoSsPp) and structural information on unknown compounds is highly desirable. To accomplish this successfully, an understanding of the gas-phase fragmentation chemistries in play is of substantial benefit.Ben StructureHe and his students work on how and why different analyte ions form particular conformations, and what effect this has on their gas-phase fragmentation chemistry. They utilize a wide assortment of analytical approaches based around mass spectrometry (accurate mass identification, HPLC,  isotopic labeling, tandem mass spectrometry, hydrogen/deuterium exchange, “action” IR spectroscopy), and cutting edge computational methods (molecular dynamics, density functional theory, ab initio, and RRKM calculations). In so doing, students acquire a wide variety of valuable skills, and are exposed to multiple approaches to problem-solving.
