Understanding human exposure to perfluoroalkyl phosphinic acids (PFPiAs)
  • PhD 2014-Present
  • BSc 2013 (Carleton)

My research focuses on understanding the fate of perfluorinated contaminants in the environment. Although they have been detected in a variety of environmental matrices including human blood, perfluoroalkyl phosphinic acids (PFPiAs) are much less studied compared to their sulfonate and carboxylate counterparts. They have been considered persistent pollutants, however a recent study has shown evidence of metabolism in fish, by cleavage of the carbon-phosphorus bond. Metabolism is surprising, given the stability of perfluorinated acids, and the scarcity of C-P bonds in nature. I am currently working towards understanding their metabolism and fate in rats, as a mammalian model species.

So far I have presented by work twice at the SETAC North America meetings (Salt Lake City, 2015 and Orlando, 2016). Outside research, I'm invovled in the Green Chemistry Initiative, and in my free time like to see live music and travel.
