Lika Guhathakurta, NASA Heliophysics Division

Madhulika (Lika) Guhathakurta is an Astrophysicist with NASA’s Heliophysics Division at HeadQuarters. Before joining HQ in December of 1998, her career focused on studying the importance of the scientific exploration of space in particular understanding the Sun as a star and its influence on the planet Earth, with research focus on the Sun’s outermost layer, the solar corona. She has been a Co-Investigator on five Spartan 201 missions on aboard space shuttles to study the solar corona and nine eclipse expeditions. Led the Living with a Star Program for the past 15 years whose goal is to understand and ultimately predict solar variability and its diverse effects on Earth, human technology and astronauts in space, also known as "Space Weather”. She has led missions such as STEREO, SDO, Van Allen Probes, Solar Orbiter Collaboration, Parker Solar Probe and others. She initiated Space Weather to be a permanent agenda item at UNCOPUOS in 2013 and started International Living with a Star (ILWS) in 2003. Partnered with museums to produce planetarium and 3D IMAX shows that are being exhibited internationally. Created graduate level textbooks to train the next generation in heliophysics and led 2017 Eclipse science. Presently she is on detail to NASA Ames Research Center exploring concepts for new initiatives by fusing science, technology and public-private partnership.

Sofia Paraskevi Moschou

At the High Energy Astrophysics Division of the Center for Astrophysics Dr. Moschou’s role is to use her background on solar physics and try to apply it and improve our understanding of stellar activity on different types of stars. Her research interests include the study of solar and stellar outflows and activity events, such as coronal mass ejections (CMEs), flares, and energetic particles. More specifically, her work is focused on phenomena associated with magnetic reconnection, such as shocks, particle acceleration and multi-wavelength emission and their energy partition in different regimes. Finally, I am particularly interested in studying the effects of stellar activity on (exo)planetary magnetospheres and habitability.

Dr. Moschou’s first scientific work was during her undergrad years at the University of Athens, when she studied solar jet dynamics by analyzing SDO and STEREO data for her bachelor thesis. Staying in Greece for her Master thesis she did a semi-analytic study of MHD instabilities in astrophysical jets. She obtained her Ph.D entitled “Dynamics of the solar atmosphere and solar wind modeling” in 2016 at the KU Leuven on Computational Plasma Astrophysics. She is currently a Postdoctoral Researcher at the Harvard & Smithsonian Center for Astrophysics.
