Lesley Chesson is the President of IsoForensics. She obtained her M.S. from the University of Utah in 2009 and has more than 12 years of experience conducting stable isotope analyses. Lesley was approved as a forensic practitioner by the Forensic Isotope Ratio Mass Spectrometry (FIRMS) Network in 2013 and is a member of the FIRMS Steering Group. She has used stable isotope forensic techniques to examine documents, drugs, explosives, feathers, microbes, human hair and fingernails, tap water, and a variety of foods and beverages. She has also aided various law enforcement agencies in investigations via the stable isotope analysis of unidentified human remains.
Jim Ehleringer is a senior scientist at IsoForensics and a Distinguished Professor of Biology at University of Utah. He obtained his Ph.D. from Stanford University in 1977. Jim was approved as a forensic practitioner by the Forensic Isotope Ratio Mass Spectrometry (FIRMS) Network in 2013. He is a founding member of IsoForensics.
Thure Cerling is a senior scientist at IsoForensics with interests in the isotope biogeochemistry of processes occurring near the Earth's surface. He has broad experience in the chemistry of soils, sediments, plants, and animals in both field and laboratory conditions. He has worked extensively in North America and Africa on problems of geology and human origins. He obtained his Ph.D. from the University of California at Berkeley in 1977 and has served on the U.S. Nuclear Waste Technical Review Board. Thure, a member of the U.S. National Academy of Sciences, is a founding member of IsoForensics.
Brett Tipple is a research scientist at IsoForensics with interest in the fields of isotope forensics, isotope geochemistry, paleoclimatology, and modern and ancient plant ecology. He primarily uses stable isotope ratios and abundances of organic molecules to constrain modern and ancient environmental conditions of oceans, terrestrial ecosystems, and atmospheres. Some of his current areas of research are modern plant ecophysiology and applications of heavy isotopes from human tissues for provenancing. Brett obtained his Ph.D. from Yale University in 2009.
Mike Lott is a chemist at IsoForensics with 20 years of experience conducting stable isotope analyses on a wide variety of materials. His interests lie in the forensic applications of stable isotope analysis for various materials. His investigative work includes drugs, natural fibers, fertilizer, and synthetic products. Mike has also worked with law enforcement in the development of methods for the analysis of narcotics and explosives. He graduated with B.S. degrees in Chemistry and Biology from the University of Utah in 1995. Mike was approved as a forensic practitioner by the Forensic Isotope Ratio Mass Spectrometry (FIRMS) Network in 2013. He is a founding member of IsoForensics.
John Howa is a chemist at IsoForensics with more than 14 years of experience using stable isotope analysis. He has worked on several projects since 2000 that included stable isotope and component analysis of explosives, bacteria, illegal drugs, and other chemicals derived from plant material and petroleum. His current interests involve investigating isotopic variability in manufactured goods. John received his B.A. in chemistry from Reed College in 1999.
Janet Barnette is a research scientist at IsoForensics with broad interests in applying stable isotope analysis tools to the study of forensics and the environment. With more than 10 years of experience, she has investigated drugs, explosives, manufactured goods, microbes, and environmental waters. Most recently, she has used radiocarbon techniques to study illegal drugs and urban ecosystems. Janet received her B.S. degree in biology from the University of Utah in 1998.
