Joy McGrath has been with Exponent since February 2017 as a Senior Managing Scientist in the Health and Environmental Group. Previously she worked at HydroQual/HDR for 25 years. She has a BS in Biochemistry and a MS in Environmental Engineering both from Manhattan College. Her interest is in understanding the bioavailability of organics in the environment and their effects on aquatic organisms. Ms. McGrath was a co-author on the original research for the target lipid model (TLM), a framework for deriving water and sediment criteria for mixtures of non-polar chemicals that act via narcosis, such as hydrocarbons. The TLM has been adopted by the U.S. EPA and other international environmental agencies for use in deriving sediment criteria for the protection of benthic invertebrates from exposure to mixtures of polycyclic aromatic hydrocarbons (PAHs). She has published several subsequent manuscripts on the TLM model refinements and its application to various environmental media. This is her second year on the SETAC HDC board and has been impressed with the board members and their commitment to the success of the chapter.
When not working, Joy has fun on the Spartan racecourse, crawling under barbed wire, carrying sand bags up black diamond ski hills, climbing over walls and traversing through lakes or crazy monkey bars. She lives in Rockland County, NY with her two kids and a dog, Maxie.
