Vladimir Airapetian is a Research Professor at American University, DC and Senior Scientist at NASA GSFC.

He is leading an international effort to understand the effects of exoplanetary space weather on climate and habitability of terrestrial type exoplanets using a multi-observatory observing efforts and numerical simulation techniques.

Airapetian is a member of the Steering Committee of NASA’s The Nexus for Exoplanet System Science (NExSS), Prebiotic Chemistry and Early Earth Environment Research Coordination Networks (RCN), a member of leadership of Sellers Exoplanetary Environment Collaboration (SEEC), PI of NASA’s Exobiology program on theoretical and experimental studies of prebiotic chemistry initiated by the effects of magnetic activity from the young Sun and active solar-type stars. He is a PI of the TESS Cycle 1 proposal to characterize the signatures and effects of magnetic activity of young solar-type stars on nearby exoplanetary systems, an integral part of the current proposal, and Co-I of another TESS Cycle 1 proposal to study effects of flares from M dwarfs on exoplanets. Airapetian is also involved into the NASA/SEEC study to model the rate of atmospheric escape from terrestrial exoplanets driven by XUV flare emission and dynamic pressure of winds from young solar-type stars and M dwarfs.
