Dr. Joseph Khoury’s experience in chemistry includes environmental analysis, nanotechnology, and laser spectroscopy. He received a B.S. with Distinction in Chemistry and Mathematics from The Ohio State University, an M.S. from Northwestern, and a Ph.D. in physical chemistry from UCLA, where he developed a procedure to isolate nanometer-sized metallic crystallites into a series of discrete sizes using fractional crystallization and liquid and gel chromatographies, and then characterized their electronic properties. As a postdoctoral fellow at the Rowland Institute at Harvard, he designed and built a nanospray/ion trap/laser-induced fluorescence assembly to achieve zero background detection to do the first measurements of protein fluorescence in electrospray droplets. He then took his experience with chemical instrumentation into the field of environmental analysis at the Los Angeles County Sanitation Districts Water Quality Laboratory. As a member of the Research Group, he developed instrumental methods using Gas Chromatography with various detectors including triple quadrupole Mass Spectrometry to analyze for Volatile Organometallics in Landfill Gas; Nitrous oxide for greenhouse gas inventory; Purgeable Organics in Wastewater; SPME of Volatile fatty acids, and odorous compounds. He is now a Supervising Scientist leading a team of talented analytical chemists and laboratory technicians using advanced instrumentation to measure Volatile Organic Compounds in both air and water samples from a wide variety of sources.An ACS member since 1983, Dr. Khoury has served in various roles for the Southern California local ACS section including section Chair and Secretary, and the committee for Project SEED.Specialties: Wet Chemical and Instrumental Analytical Methods,GC/Triplequadrupole Mass SpectrometryTwo-Dimensional Gas ChromatographyGas Chromatography
