Our research group studies the interactions between the biosphere and the atmosphere to understand how vegetation affects atmospheric chemistry and climate. The biosphere is a living and dynamic component of the Earth System, and is constantly responding to the world around it. Our research focuses on understanding how emission from the biosphere can affect atmospheric chemistry and air quality, as well as understanding how changes at the land surface can affect regional climate.

Winter 2022

  • Congratulations to graduate student Samar Minallah for receiving an NCAR ASP Postdoctoral Fellowship! Samar will be working with CGD on ice sheet modeling.
  • New paper on the impact of climate on future pollen emissions led by graduate student Yingxiao Zhang is now published at Nature Communications. See the associated media articles from CNN, National Geographic, NBC News, the AP, the Atlanta Journal-Constitution, New Scientist, and NPR’s All Things Considered. We worked with The Conversation to provide a summary piece as well!
  • Congratulations to graduate student Yingxiao Zhang, recipient of the UM College of Engineering Richard F. and Eleanor A. Towner Prize for Distinguished Academic Achievement award!

    • Friday, December 17 C54C-07: Modeling the Himalaya-Karakoram-Hindukush glacial mass balance and ice dynamics using the Open Global Glacier Model (Graduate student Samar Minallah)
  • New paper alert – former postdoc Dandan Wei has a model update paper out that evaluates the 1D canopy-chemistry FORCAsT model with the 2016 UMBS PROPHET observations.
  • Frontiers in Atmospheric Chemistry Seminar Series (FACSS) is back for Fall 2021! Talks will be every other week this term with our speaker lineup here. Sign up in advance to receive a unique webinar link every week. Students at UM can sign up for CLIMATE 501.003 for a one-credit class that includes paper discussions.
  • Graduate student Samar Minallah finally gets to move out to Boulder as part of her UCAR Next Generation Fellowship – Samar will be working with CISM and the Open Global Glacier Model on Himalayan ice sheets. (How is that we are now working on ice sheets? Good question…. but it’s been a fun project so far and a great collaboration with colleague Jeremy Bassis from CLaSP and Bill Lipscomb from NCAR)
  • UM Graduate students: Interested in developing real climate solutions? Take a look at the new Rackham Climate Solutions Certificate launched by CLaSP and SEAS to combat climate change. Apply for the program by November 1!
