Hi, I'm Drew, and I am a postdoctoral associate at the Duke University Nicholas School of the Environment. Welcome to my organic, fair trade, artisanally-crafted 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):

Pendergrass, D.C. Jacob, D. J., Balasus, N., Estrada, L., Varon, D. J., East, J. D., He, M., Mooring, T. A., Penn, E., Nesser, H., & Worden, J. R. (2025). Trends and seasonality of 2019–2023 global methane emissions inferred from a localized ensemble transform Kalman filter (CHEEREIO v1.3.1) applied to TROPOMI satellite observations. Atmospheric Chemistry and Physics, 25(21), 14353–14369. Link to paper (open access). Link to PDF.
Figure: Annual posterior methane emission trends for 2019-2023 disaggregated by region and sector. Emissions are inferred using a localized ensemble transform Kalman filter applied to TROPOMI satellite observations. Panels (a) and (b) show posterior emission changes relative to 2019, disaggregated by region and sector respectively. Inset percentages show changes relative to 2019 values for selected regions/sectors. Error bars show range of the inversion ensemble for the global emission trend. Panel (c) shows 2019-2023 trends in posterior emissions by region obtained from linear regression.
You can learn more about my research on the projects page, or you can read through all of our scientific papers and presentations on their respective pages.
