David Klein has been working at The Institute of Environmental and Human Health at Texas Tech University since 2011 and currently serves as an Associate Professor of Environmental Toxicology. His areas of expertise include a strong chemistry background in natural products, environmental and clinical chemistry, work with human clinical samples with The Centers for Disease Control, Laboratory Response Network-Chemical and in 2014 he became a Verified Toxicological Chemist through the National Register of Certified Chemists (NRCC). He also serves as the Chair-Elect of the South Plains Section of the American Chemical Society.
Dr. Klein received his B.S. in Chemistry from the University of Texas at San Antonio, an M.A.T. from Texas Christian University, and his Ph.D. form the University of Hawaii in Chemistry. He has worked as a Branch Chief in the Chemical Analysis Laboratory for the Hawaii Dept. of Agriculture, and a Contaminants Assessment Laboratory Director for Texas Parks and Wildlife. He teaches graduate courses in Advanced Topics in LC-MS, Analytical Toxicology, and Chemical Sources and Fates in Environmental Systems.
Professor Klein has a wide range of research interests including: 1. Detection and quantitation of metals and metalloids by ICP-MS 2. Isolation, purification, detection and quantitation of organic compounds by GC-MS and LC-MS 3. Purification and identification of biologically active natural products 4. Identification of chemical communication compounds from marine organisms with HIMB 5. Identification of toxic and endocrine disrupting compounds, and identification and quantitation of compounds in wastewater and drinking water.
Research in his lab is focused on three major instrument platforms; inductively coupled plasma-mass spectrometry, gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. He currently belongs to the American Chemical Society, the American Association for Mass Spectrometry, and the Society for Environmental Toxicology and Chemistry. He has served as the Chair-Elect with the South Plains Section of the American Chemical Society, as a Texas Tech Service Learning Fellow, and a National Register of Certified Chemists (NRCC) Toxicological Chemist.
