Biography
Darek Lis joined the submillimeter group at Caltech in 1989 after obtaining his PhD from the University of Massachusetts, Amherst. He was Co-Principal Investigator and Deputy Director of the Caltech Submillimeter Observatory, as well as a member of the US Herschel HIFI Science Team. From 2014 to 2019 he was Professor at Sorbonne University in Paris and Director of the Laboratory for Studies of Radiation and Matter in Astrophysics and Atmospheres, a scientific department of Paris Observatory. He returned to Caltech in 2019 as Scientist at the Jet Propulsion Laboratory. He was a recipient of NASA Group Achievement Awards in 2010 and 2014 and NASA Exceptional Scientific Achievement Medal in 2021. In 2021 he was elected to the Organizing Committee of the International Astronomical Union, Commission H2 Astrochemistry.



Research
Darek Lis's research interests include star formation, astrochemistry and high-resolution molecular spectroscopy of the interstellar medium and Solar System small bodies, as well as submillimeter heterodyne instrumentation. Using ground-based and space-borne far-infrared facilities, including Caltech Submillimeter Observatory, Infrared Space Observatory, Herschel Space Observatory, Stratospheric Observatory for Infrared Astronomy, Atacama Large Millimeter/submillimeter Array, James Webb Space Telescope, and Deep Space Network he has studied molecules and their isotopic composition to understand the physics and chemistry of the interstellar medium, as well as the origin of Earth's oceans. Currently he is a Science Affiliate for The PRobe far-infrared Mission for Astrophysics (PRIMA) and a co-Investigator for Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths (ASTHROS).
