Pedro completed his PhD at the University of Saskatchewan. He is studying the atmospheric chemistry of chlorinated and fluorinated molecules.
Dr. daniel Persaud
Postdoctoral Researcher, 2026-present
Daniel completed his PhD at York University. He is using ambient atmospheric measurements to advance our understanding of PFAS atmospheric abundance, sources, and fate.
graduate students
devon mcgrath
PhD, Memorial University, 2016-present
Devon completed his BSc(Hon) at St. Francis Xavier University. His project focuses on developing and testing novel materials specific to atmospheric pollutants. He is co-supervised by Prof. Michael Katz.
Jessica Clouthier
PhD, York University, 2018-present
Jessica completed her BSc(Hon) at Laurentian University, followed by a MSc at the University of Toronto before joining the group in September 2018. Her work focuses on the development of analytical methods to test our understanding of atmospheric formation and transport of contaminants.
mayré rodríguez
PhD, York University, 2022-present
Mayré joined the group in fall of 2022. Her project involves the deployment of the AIM-IC-MS to measure atmospheric acids in ambient gases and particles.
nasrin dashti
PhD, York University, 2023-present
Nasrin joined the group in May 2023. Her work focuses on understanding the chemistry of surfaces and solids that affect sources and fate of PFAS.
na-Yung Seoh
PhD, York University, 2023-present
Na-Yung joined the group in May 2023. Her research focus is the sources and fate of halogenated chemicals in the atmosphere.
undergraduate students
nevadha murugarajan
NSERC USRA Student, York University, 2026
Nevadha is working to improve measurements of PFAS in atmospheric deposition, and better understand their sources.
