CONJURE UP ALL THE DATA YOU NEED Jack Henion (left) is associate professor of toxicology at the New York State College of Veterinary Medicine of Cornell University in Ithaca, N.Y. He is assistant director of the Equine Drug Testing and Toxicology Program at Cornell and holds a B.A. from Alfred University, an M.S. in organic chemistry from the Rochester Institute of Technology, and a Ph.D. in analytical organic chemistry from the State University of New York at Albany. After postdoctoral research in ion cyclotron resonance MS at the University of North Carolina at Chapel Hill, he joined the chemistry department of Cornell as director of the NIH Biotechnology Resources High Resolution Mass Spectrometry Facility. After two years he joined the veterinary college faculty, where he has continued work in LC/MS as it relates to the real world of racehorse drug testing and toxicology. Edgar Lee (center left) is a secondyear graduate student interested in capillary SFC combined with MS. He is currently modifying a bench-top capillary GC/MS for capillary SFC/ MS. He holds a B.A. from Brigham Young University and is working toward a Ph.D. at Cornell.
Thomas Covey (center right) holds a B.S. degree from Holy Cross College and an M.S. from Cornell. Covey is currently completing his Ph.D. in analytical toxicology at Cornell in areas including the ultratrace isolation and identification of toxic substances found in biological samples. He has had extensive experience with various modes of LC/MS and LCIMS/MS. Andries Bruins (right) received his undergraduate training at the University of Amsterdam, the Netherlands, and earned his Ph.D. at the same university on fragmentation mechanisms and ion molecule reactions in MS. After postdoctoral research on negative-ion CI and linked scans in MS at the University of Warwick, England, he joined the Department of Pharmacy, State University, Groningen, the Netherlands, as a faculty member in charge of the MS service facility, where he did research on negative-ion CI, desorption CI, and LC/MS. He currently is on a oneyear leave as a visiting assistant professor at Cornell University.
