The group is recognized for their pioneering work in dual frequency-comb spectroscopy, and using it to create and translate a revolutionary new approach to methane leak detection and other atmospheric gas sensing with broad applications in defense, agriculture, atmospheric science and the oil/gas industry.  The group transformed a lab experiment to a robust field instrument that can detect gases with 10-100x higher precision and 10-100x longer air paths than existing open-air multi-gas sensors – sensitive enough to detect methane leaks as small as ¼ of a human breath at miles of distance.
