This work opens new questions about the role of biological materials to EPFRs in the environment, and I’m excited to continue exploring this direction in future research.

We found that pollen is a major contributor to EPFRs in urban grime in the spring in North Carolina. Additional experiments using commercial pollen samples and complimentary laboratory photoaging experiments show how EPFR levels change with light exposure and atmospheric deposition.

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 😂 pubs.acs.org/doi/full/10....

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...

Thanks Jen! Hamilton has been trying to prepare me for living life in a windy place... 😅 but Lethbridge is something else!

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.

An interesting result includes observations of a single wildfire smoke day contributed over 20% of total grime PAH loadings in Calgary (!!) during this study’s 3-month sampling period, showing how wildfire inputs can dominate the grime composition during wildfire season 🔥🌲🏠

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? #ChemSky

Potential bias in the ozone measurements limits our results; however even if we overcorrect the bias, the increase in ozone during wildfires persists!

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.
Schematic overlaid over a panorama of smoky mountains and the ocean. The schematic shows the emission of fire plumes and production of ozone, mixing with urban emissions.
