Check out our most recent SEARCH Center paper on the effects of building efficiency scenarios on indoor air quality

Hats off to PhD student Colby Buehler for his indoor air quality analysis under future building energy efficiency scenarios, out now in Science Advances. Was great to collaborate with Economics Prof. Ken Gillingham from Yale School of the Environment on this multidisciplinary EPA SEARCH Center paper, along with Pei Huang (now at the Leibniz Centre for European Economic Research) and Prof. Jordan Peccia (Yale Chemical & Environmental Engineering).

Mask testing paper out in JESEE

Our new paper from the Yale CEID on mask testing during the COVID-19 shutdown is out in Nature’s JESEE. Still testing in the CEID (Center for Engineering Innovation & Design) today with over 100 masks tested now!

Additional info on our accessible mask testing setup and PPE results are posted at Proud to have worked on this with Kate, Larry, & the CEID to support frontline healthcare workers.

Mask testing to support frontline healthcare workers: Not all masks are created equal!

Our survey of an actual hospital PPE inventory shows that with the influx of non-certified masks, not all “real” masks function properly. These aren’t just alternative/homemade masks, but masks that purportedly function as an N95 mask.

Info on our accessible mask testing setup and PPE results are posted at &

Proud to have worked on this with Kate Schilling, Larry Wilen, all our other awesome co-authors, & the CEID to support frontline healthcare workers. We hope communities with limited testing resources around the globe can use this for data-driven PPE decision-making.

Check out the SpinWheel – a programming teaching tool, launching on Kickstarter!

Gentner Lab student Jenna Ditto and a team of engineering and physics PhD students are developing the SpinWheel: a colorful, wearable kit to teach and learn physics and computer science in a fun, tangible way! The SpinWheel can be sported as a keychain or jewelry, and comes with a set of activities that you can follow along with to program the device into a step counter, a compass, a colorful display of LEDs, and more. The team is launching their kit on Kickstarter on Monday March 16. Visit their Kickstarter page to support them on March 16, or their website for more information about the project! All proceeds go towards funding Yale Society of Women Engineers STEM outreach events for students in Connecticut.

Third-Hand Smoke paper in Science Advances

Movie goers sitting with dangerous chemicals from smoking around them.Congratulations to Roger on his super cool paper that came out today in Science Advances, which is already generating a lot of interest. Thanks to the Max Planck Institute for Chemistry and the Alexander von Humboldt Foundation for hosting me in Germany as a Research Fellow and enabling this exciting collaboration. Check out the paper at as well as the press release and multimedia at Follow us at @drew_gentner and @YaleSEAS on twitter for updates.

Understanding the molecular-level composition of organic aerosol

Check out Jenna Ditto’s new paper in Environmental Science & Technology Letters using MS/MS to look at organic aerosol functional groups across OA complex mixtures “Nontargeted Tandem Mass Spectrometry Analysis Reveals Diversity and Variability in Aerosol Functional Groups across Multiple Sites, Seasons, and Times of Day” at A very cool multi-site and multi-season study to elucidate the molecular-level composition of organic aerosol. Nice work Jenna!
