Levi studies in the field of atmospheric chemistry where he is advised by Dr. Mark Zondlo. His research interests focus on the topic of quantifying emissions from local sources using mobile laboratory and UAV-based techniques. This work is facilitated by the development and testing of new, mid-infrared based, compact laser spectrometers that can meet the low power and weight requirements of these platforms. This capability is especially applied to understanding the magnitude and sources of methane leakage from unconventional natural gas production systems, which have proliferated recently in the U.S. and globally. This research has implications for climate risks from shale gas production and is key to understanding the footprint of natural gas relative to other energy sources.
