Chair: Stefanie Milam (NASA/GSFC) [2023 - 2025]

Dr. Stefanie Milam works in the Astrochemistry Laboratory at the NASA Goddard Space Flight Center (Greenbelt, Maryland USA). She is an expert in rotational spectroscopy, observations, and laboratory modeling of astrochemistry and molecular astrophysics of the interstellar medium, evolved stars, star formation regions, and comets with an emphasis on isotopic fractionation and astrobiology of primitive materials. 

Dr. Milam maintains a renowned observational program with radio telescopes around the world, and with space-based observatories, to routinely observe comets as part of an international collaboration. She leads the SubLIME laboratory at GSFC that is dedicated to simulate interstellar/cometary/planetary ices and detect trace species employing the same techniques used for remote observations to help constrain the chemical complexity of the ices, the amount of processing that occurs, and interpret past and present data from missions that observe ice features. Dr. Milam has been working on the James Webb Space Telescope (JWST) as Deputy Project Scientist for Planetary Science since 2014. Under this role she helped establish the next generation space telescope as a planetary science resource as well as helped implement laboratory support in general observing proposals. She is involved in a number of future missions and concepts that range from small bodies in the solar system to next generation space telescopes.

Past Chair: Murthy Gudipati (NASA Jet Propulsion Laboratory) [2023 - 2025]

Dr. Murthy Gudipati was born and raised in southern India. He received his Ph.D. from the Indian Institute of Science, Bangalore, India in 1987. After a 3 year post-doctoral collaboration with Prof. Josef Michl (at the University of Texas at Austin), he joined University of Cologne, Germany in 1990, where he was awarded Habilitation in Physical Chemistry (tenure) in late 1998. In 2007, Dr. Gudipati joined NASA's Jet Propulsion Laboratory where he studies the evolution of ices in the universe.

Dr. Gudipati's research interests can be broadly defined as understanding the physics and chemistry of interstellar and Solar System ices through laboratory simulations, observations and instrumentation. His research in recent years has focused on physics and chemistry of cryogenic ices. Knowledge acquired through laboratory experiments on ices is crucial in order to develop next generation instrumentation concepts for orbiter remote sensing, in-situ lander, rover, or manned missions.

Treasurer: Christiaan Boersma (NASA Ames Research Center) [2022 - 2025]

Dr. Christiaan Boersma received his PhD in Astronomy (thesis) in 2009 and was then awarded a NASA Postdoctoral Program fellowship with the Astrophysics & Astrochemistry Laboratory Group at NASA Ames Research Center. After concluding this fellowship in 2012, he moved to the San José State University Research Foundation position he currently holds in support of a collaboration with the NASA Ames Astrophysics and Astrochemistry Laboratory Group. Dr. Boersma's research focuses on the role of polycyclic aromatic hydrocarbons (PAHs) in a multitude of astronomical environments, with special interest for intermediate-mass star-forming regions. He conducts his research through analyzing and interpreting astronomical data obtained by today's state-of-the-art ground-, air- and space-based observatories, e.g., VISIR, SOFIA and Herschel, using a combination of laboratory and synthesized spectroscopic data. The NASA Ames PAH IR Spectroscopic Database (PAHdb) plays an important part in his research. Dr. Boersma had a leading role in the assembly and construction of PAHdb and its associated tools. PAHdb now guides the development of new methodologies in analyzing astronomical data, which are particularly relevant to data returned by future astronomical observatories, like the JWST.
