Julian Fortney

Polymer Science & Materials Chemistry
Menlo Park

Mr. Fortney is an analytical chemist who specializes in chemical characterization of consumer products and environmental samples. He is skilled in numerous chromatography techniques including IC, GC-MS (purge and trap, liquid injection, thermal desorption), and LC-MS (HPLC-UV, HPLC-MS-MS). In addition to his analytical expertise, Mr. Fortney is a trained biologist with experience in nucleic acid extraction, PCR and next generation sequencing preparation and analysis. He has worked to combine these disparate disciplines to understand the role of complex compounds (crude oil, Ligno-cellulose) in biological systems with a focus on biodegradation (biotic and abiotic).

Prior to joining Exponent, Mr. Fortney was a research professional at Stanford University investigating nitrogen species in deep marine sediments to better understand global nitrogen cycling. He has held research positions at the University of Tennessee, Knoxville and Lawrence Berkeley National Laboratory, collaborating with British Petroleum to measure the effectiveness of oil dispersants in real and simulated marine spills.
