Craig M. Butt is Staff Application Specialist in the Environmental, Food & Beverage division of SCIEX with over 20 years of mass spectrometry experience. While at SCIEX he has developed methods for targeted screening of pesticides in cannabis, non-target screening of pesticides in fruits & vegetables, PFAS in water using high resolution accurate mass spectrometry, and qualitative profiling of natural products. He obtained his Ph.D. in environmental chemistry at the University of Toronto where his thesis research investigated the fate of poly- and perfluorinated organic compounds (PFAS) in biological systems. He was a NSERC post-doctoral research fellow in the Nicholas School of the Environment at Duke University, later becoming a research scientist in the department. His research at Duke investigated the disruption of thyroid hormone regulating enzymes by halogenated organic contaminants using in vitro assays, analytical method development of phosphate-based flame retardant (PFR) urinary metabolites; PFR exposure in children and adults; and measuring human PFAS exposure in serum, handwipes and wrist bands.
