Bio:

Prof. Klein is a chemist with experience in natural products, environmental and clinical chemistry. He joined the faculty at TIEHH in 2012 after working with environmental chemistry laboratories in Texas and Hawai’i. He comes to TIEHH from heading the Chemical Terrorism Response Lab (part of the Centers for Disease Control Laboratory Response Network) in Texas. Prof. Klein has a wide range of research interests.

 

     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-MSn

     3. Purification and identification of biologically active natural products

     4. Identification of chemical communication compounds from marine organisms with HIMB

     5. Identification of toxic compounds

     6. Identification and quantitation of compounds in wastewater and drinking water

     7. Endocrine disrupting compounds

 

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.  Students work in a supportive environment to learn the principles of analytical chemistry as applied to a wide variety of problems as suits their interests.
