Craig obtained his PhD in environmental chemistry at the University of Toronto, under the co-supervision of Dr. Scott Mabury and Dr. Derek Muir (Environment Canada), where he investigated the fate of PFAS in biological systems. Craig was then an NSERC postdoctoral research fellow and research scientist at Duke University, under the guidance of Dr. Heather Stapleton. Among other interesting topics, Craig's postdoctoral research involved measuring human PFAS exposure in serum, hand wipes, and wristbands. In his 20 years of mass spectrometry experience, Craig has published 48 peer-reviewed manuscripts, many of which are on PFAS, are globally recognized, and are highly cited. Within SCIEX, Craig is the applications lead for all things PFAS and has contributed to a variety of PFAS-specific applications, including EPA Methods 537.1 and 533.
