Hi, I'm Drew. My GMO-free, fair trade, gluten-free website is lovingly built from whatever I decide to post online. For that reason, it has a lot of stuff on it. Navigate as follows:
- If you are interested in SCIENCE: I just defended my PhD at Harvard in Environmental Engineering, and I will be starting as a postdoc at the Duke Nicholas School of the Environment in July 2025. 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: Outside science, my 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, my popular writing, and academic publications in history, architecture, and environmental studies. I am happy to do course visits, give talks, etc. on this material; you can reach me at drew [at] drewpendergrass [dot] com (or the academic address in my CV).
- 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.
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. For upcoming events, check out my events page. If you want to follow my work, you can subscribe to my newsletter below (expect emails every six months or so at most):
The latest science!
Pendergrass, D.C., Jacob, D. J., Oak, Y. J., Lee, J., Kim, M., Kim, J., Lee, S., Zhai, S., Irie, H., & Liao, H. (2025). A continuous 2011–2022 record of fine particulate matter (PM2.5) in East Asia at daily 2-km resolution from geostationary satellite observations: Population exposure and long-term trends. Atmospheric Environment, 346, 121068. Link to paper (open access). Link to PDF.
Figure: GOCI gap-filled aerosol optical depth (AOD), PM2.5 from air quality networks, and GOCI PM2.5 obtained by applying a RF algorithm to the GOCI AOD data. Data are annual means for 2012 (the first year with complete GOCI data), 2017, and 2022. The gap-filled AOD data provide continuous 2×2 km2 coverage of eastern China, S. Korea, and Japan for 2011-2022. The PM2.5 network data are from individual sites and enlarged for visibility. The S. Korea insets in the middle panels provide greater resolution of network data gaps. PM2.5 measurements from the AirKorea network started in 2015, and the S. Korea PM2.5 network data shown for 2012 are from a RF reconstruction.
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.
A Brief Q&A
Q. How can I contact you or keep up with your work?
A. You can reach me at drew [at] drewpendergrass [dot] com (or the academic address in my CV); I'm pretty quick with email. However, if your email is unpleasant, you should direct it to grievances@drewpendergrass.com, an inbox I definitely read.
If you want to keep up with new projects, the best way is to subscribe to my newsletter. I send short emails a few times a year with major updates on science and writing. 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.
Q. Who are you?
A. Well, to start off, I am not a closed, non-orientable, boundary-free manifold, my mind's eye exists only in a figurative sense, I have never advocated on behalf of, or against, the Free Silver movement, I am not to my knowledge a victim of a mummy's curse, and I have never commanded an army composed of more than 100,000 soldiers. Besides that, I am a doctoral student in Environmental Engineering at Harvard University, and I freelance on the side for publications including Harper's and The Guardian. I'm also at work on a sci-fi novel and have a book under contract with Verso on economic democracy. In my activism and organizing, we work to make ecological democracy a reality in my home of Massachusetts. I am also a long-time steward in the Harvard Graduate Students Union (UAW local 5117). For more information, you can check out my projects page or my CV.
Q. Why does this page keep changing?
A. This page is randomly generated by the server on each load. Most of the page's contents are not displayed on one particular load, so for the full experience reload a bunch of times.
