Jody C. May
Research Assistant Professor, The McLean Group
Director of Technology, Center for Innovative Technology
University of Central Arkansas – B.S. in Chemistry
Texas A&M University – Ph.D. in Analytical Chemistry
EDUCATION Jody received his B.S. in Chemistry from the University of Central Arkansas in 2001. He pursued an undergraduate research thesis under the guidance of Prof. Bill Taylor studying the state specific reactivity of transition metals in the gas phase.
Under the direction of Prof. David Russell at Texas A&M University, Jody completed his Ph.D. in Analytical Chemistry in 2009. His graduate projects included the design of novel ion trap geometries for the ion cyclotron resonance experiment and developing ion mobility instrumentation based on surface induced dissociation and time-of-flight mass analysis. His final dissertation project focused on the development and characterization of a cryogenic ion mobility-mass spectrometer designed for high resolution ion mobility analysis.
After this, Jody began his postdoctoral work with Prof. John McLean in 2009 where he began implementing a development program in ion mobility-mass spectrometry (IM-MS) instrumentation. He was appointed to the title of Research Professor in 2011 and continues to evaluate next-generation instrumentation for structural mass spectrometry research. Currently, his interests focus on fundamentals of ion mobility measurements and developing IM-MS for broad-class analytical applications, specifically in the areas of metabolomics, lipidomics, and isomeric differentiation.
SPECIALTIES & FOCUS Jody is experienced in mass spectrometry-based analytical instrument development (design, construction, and operation), analytical instrument architecture, scientific communication and graphical design of fundamental scientific concepts, bridging collaborative efforts, and dissemination of research via presentations and peer-reviewed publications.
Having constructed two variable temperature drift tube ion mobility spectrometers and two hybrid ion mobility time-of-flight mass spectrometers that utilized novel surface-induced ion fragmentation configurations at Texas A&M, Jody initiated an instrumentation development program at Vanderbilt to develop and evaluate the next generation of high-content mass spectrometers based on hybrid, multi-stage separation technologies.
Recently, he worked with Agilent Technologies to develop and commercialize an ion mobility-mass spectrometer focused on high-precision ion mobility measurements. This and similar technologies are now being offered commercially by several vendors, which has shifted his current focus to applying these advanced analytical technologies towards comprehensive and untargeted molecular characterizations, as well as the integration of ion mobility measurements into high-throughput multi-omic workflows. Jody is particularly interested in developing informatic strategies that utilize these multiple dimensions of analytical information towards more complete and unambiguous characterization of unknown compounds. Metabolomics and lipidomics are particularly challenging, given the high degree of isomeric complexity experienced with these class of molecules, yet their limited m/z range offers an opportunity to address the isomer challenge with contemporary techniques.
