Meet Our Speakers
Genevieve Hodson
Senior Technical Specialist, Phenomenex
Genevieve graduated from the University of Texas with a BS in Chemistry located in her home town of Austin Texas. She spent 2 years of her undergraduate performing research in an Organic Chemistry Lab synthesizing intermediates. Out of school she spent 4 years as an Analytical Chemist in the QC and R&D Department of Cerilliant (a Sigma Millipore Company). There she worked with many analytical instruments but became an expert at LC by performing purity analysis, customer specific methods, validations, qc testing and stability studies on a wide range of small molecules including pharmaceuticals, pesticides, explosives and illegal substances. From there she moved to Los Angeles California where she worked at Johnson and Johnson and then a small dietary supplement company. After Genevieve spent a year living abroad in Israel raising her first son, she moved back to LA where she got hired as a Technical Specialist at Phenomenex. At Phenomenex she enjoys continuing to learn about chromatography every day through helping customer with all their chromatography needs!

Karl Oetjen, PhD
Senior Scientist, SCIEX
Karl Oetjen is a Senior Technical Marketing Scientist for Food, Environmental, Forensic, Clinical and Cannabis applications at SCIEX. Before joining SCIEX, he completed his PhD at Colorado School of Mines (Golden, Colorado) in Hydrologic Science and Engineering under Dr. Chris Higgins. Karl’s dissertation research focused on nontarget characterization of complex surfactant mixtures, including aqueous film forming foams. This work led to the discovery several novel per- and polyfluorinated alkyl substances (PFAS) that since have been found in variety of environmental samples and industrial chemicals. Since joining SCIEX, Karl has worked with numerous labs creating and implementing both regulated and unregulated quantitative and qualitative screening methods.
