Excited to share the results from my postdoc work – and my first paper focused on environmentally persistent free radicals (EPFRs)!
Please enjoy also enjoy my artistic skills in Microsoft Paint 😂

Environmentally Persistent Free Radicals in Outdoor Surface Grime during Pollen Season
On outdoor surfaces, grime is an important substrate for the deposition and reactive loss of semivolatile and particulate bound pollutants. A previously unexplored source of grime reactivity is enviro...

Big life update: I'm starting as an Assistant Professor of Chemistry at the University of Lethbridge! 🔬📚🧪
Feeling excited to be stepping into this new role and connecting with the commuity at ULeth. Huge thanks to everyone who's helped me get here—couldn’t have done it without you.

A tricky thing about modern society is that no one has any idea when they don’t die.
Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

Wildfire Smoke Contributions to Polycyclic Aromatic Hydrocarbon Loadings in Western Canadian Urban Surface Grime
Wildfires emit large amounts of polycyclic aromatic hydrocarbons (PAHs) into the atmosphere. As PAHs emitted from anthropogenic sources are known to accumulate in urban surface grime present on buildi...

Photochemical Formation of Trifluoroacetic Acid: Mechanistic Insights into a Fluoxetine-Related Aryl-CF3 Compound
Trifluoroacetic acid (TFA) is a ubiquitous environmental contaminant; however, its sources are poorly constrained. One understudied source is from the photochemical reactions of aromatic compounds con...

Any #AtmosChem / #IndoorChem folks following me have tips for dealing with any smoke that manages to seep inside? Mainly thinking of how to clean up once the worst is over.
My best guess is wiping down surfaces and washing linens.
Am I forgetting anything?

An fun first blusky post and a Valentine's day surprise - SO excited to finally be able to share this work.
We used ozone measurements in Western Canada over two decades to investigate the effects of wildfires on measured ozone. We show the average increase during wildfires is 2 ppbv.
