Hi, I'm Drew, and I am a postdoctoral associate at the Duke University Nicholas School of the Environment. Welcome to my artisanally-crafted, low-sodium, GMO-free website! Note that many of the pages here are randomly generated by the server on each load. For the full experience, reload a bunch of times and navigate as follows:
- If you are interested in SCIENCE: In my scientific research, I use satellite data to track pollution back to its source and monitor emissions in real time, and I maintain free open-source software that allows others to do the same. I'm also interested in fine particulate matter (PM2.5) dynamics and trends, with the goal of improving air quality. If you want to learn more, check out out my ongoing projects, research papers, conference presentations, and environmental datasets. Everything is open access.
- If you are interested in THINKING THAT ISN'T SCIENCE: My interdisciplinary work imagines how humanity can democratically govern itself in an age of environmental crisis. Together with social scientists, historians, and designers, I imagine the sorts of institutions and protocols that would allow humanity to democratically manage our economy and its interchange with ecosystems. This has taken the form of books, video games, public writing, and academic publications in history, architecture, and environmental studies.
- If you are interested in MY CV: you can download it here.
- If you are interested in MISCELLANEOUS: This website is big because I have had it since high school and I don't delete things. If you search for it, you can find ephemera I have made over the years, including experimental music. I also go on podcasts and the radio with some frequency to talk about environmental issues; you can listen/read/watch here.
- If you are interested in HUMAN CONTACT: I can be reached at drew [at] drewpendergrass [dot] com, or at the academic address in my CV. However, if your email is unpleasant, you should direct it to grievances@drewpendergrass.com, an inbox I definitely read. For upcoming events, check out my events page. I keep my social media limited these days, but you can follow/DM me on Bluesky. My old Twitter is still up, but I don't use it anymore. The best way to follow my work is to subscribe to my newsletter below (expect emails every six months or so at most):

Wintertime Trends of Fine Particulate Matter (PM2.5) in South Korea, 2012–2022: Response of Nitrate and Organic Components to Decreasing NOx Emissions.

Figure: DJF PM2.5 and trends in South Korea. Panels (a) and (b) show DJF mean PM2.5 at AirKorea surface stations in (a) 2012 and (b) 2022. PM2.5 monitoring at these stations started in 2015, and data for 2012 is from a synthetic PM2.5 network produced using a random forest (RF) algorithm applied to the station data including PM10 (Pendergrass et al., 2025). Panel (c) shows the DJF emission-driven trend in PM2.5 after removing meteorological influence with a multi-linear regression (MLR) fit. Panel (d) shows observed DJF PM2.5 averaged over 25 sites in the city of Seoul, disaggregated into daytime (8-18 LT) and nighttime (22-5 LT) for weekdays and weekends. Panel (e) shows the emission-driven PM2.5 timeseries (residual from the meteorological MLR model) for the Seoul 0.25°×0.3125° grid cell (centered at 37.5°N,127.0°E) and averaging data from 37 sites.

A random interview
Blueprint from the Australian Broadcasting Corporation (radio)
19 February 2021 | Listen here
In this radio interview, my co-author Troy Vettese and I spoke with Blueprint's Jonathan Green about how land use change might help us make sense of recent global fire crises from California to Siberia, Brazil to Australia.
Additional interviews are available on my interviews page.
