Below is a video from a seminar I gave in the fall of 2020 to discuss our recent national assessment paper.
Here is a news clip about our methane mapping project from China Global News.
Here is a link to a story about our collaboration with Consolidated Edison, a NY utility company that used advanced leak detection technology to help prioritize leak repairs.
My colleague Joe von Fischer and I were featured on a CSU Research podcast to discuss the methane mapping project:
Below is a write-up of the Methane Emissions Symposium hosted by the Stanford Natural Gas Initiative that I participated in during Spring 2021.
