The McKay Research Group studies the fundamental chemistry of natural and engineered systems. We are interested in projects that seek a mechanistic understanding of the physical and chemical fate of organic compounds in the environment. Our group applies chemical principles and modern instrumentation to study aquatic chemistry. We are currently working on projects related to characterization of dissolved organic matter (e.g., structure, optical properties, and photophysical properties), aquatic photochemistry (in particular, mechanisms of reactive intermediate formation), and novel treatment technologies for remediation of persistent and hazardous chemicals, including pharmaceuticals/personal care products and fluorochemicals (e.g., PFOA and PFOS). These project areas are outlined below with a few recent publications. A full list of group publications can be found at Prof. McKay's Google Scholar page.
