Dr. Paulett C. Liewer
STEREO Project Co-Investigator, NASA Jet Propulsion Laboratory

Dr. Paulett Liewer

Dr. Paulett C. Liewer is Manager of the Astrophysics and Space Sciences Section of the Earth and Space Sciences Division at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Prior to this assignment, she served as JPL's Associate Chief Scientist. Her present research interests include modeling the solar corona, solar wind and global heliosphere and analysis and visualization of solar and solar wind data. She received a B.A. from Cornell University and a Ph. D. in plasma physics from the University of Maryland. Dr. Liewer is a Co-Investigator on SECCHI, the imaging instrument suite on NASA's Solar TErrestrial RElations Observatory (STEREO).

Dr. Spiro K. Antiochos
STEREO Project Co-Investigator, Naval Research Laboratory

Dr. Antiochos Spiro Dr. Spiro K. Antiochos of the Naval Research laboratory (NRL), heads the Solar Theory Section in the Space Science Division. His fields of expertise include solar and plasma physics. His work consists primarily of developing theoretical models to explain observations, and relies heavily on large-scale numerical simulations. Dr. Antiochos is a pioneer in computational solar physics. During his career he has worked on a number of problems related to the Sun and Heliosphere, in particular, the origins of coronal mass ejections and eruptive flares, and the heating and topology of the Sun's atmosphere. Dr. Antiochos is a co-Investigator on STEREO.

Dr. Antiochos is a Fellow of the American Geophysical Union, a recipient of the American Astronomical Society's George Ellery Hale Prize for outstanding contributions to the field of solar astronomy, and a recipient of NRL's E.O. Hulburt Award, the Laboratory's highest honor for scientific achievement.

Dr. Madhulika Guhathakurta
STEREO Program Scientist, NASA Headquarters

Madhulika Guhathakurta As a NASA astrophysicist, Dr. Madhulika Guhathakurta (also known as Lika) has had the opportunity to work as a scientist, mission designer, instrument builder, directing and managing science programs and teacher and spokesperson for NASA's mission and vision in the Heliophysics Division. Occasionally, she performs all of these roles in a single day.

Before joining NASA Headquarters in December of 1998, her career has 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 understanding the magneto hydrodynamics of 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 in white-light and UV radiation and has authored over 70 publications.

Dr. Guhathakurta is the Lead Program Scientist for NASA's initiative called "Living With a Star" (LWS) which focuses on understanding and ultimately predicting solar variability and its diverse effects on Earth, human technology and astronauts in space. The systems science behind this new kind of weather outside of Earth's terrestrial atmosphere is known as "Space Weather". She is also the Program Scientist for "Solar TErrestrial RElations Observatory" (STEREO), scheduled to launch in July 2006. STEREO is a two-year mission which will employ two nearly identical space-based observatories - one ahead of Earth in its orbit, the other trailing behind - to provide the first-ever stereoscopic measurements to study the Sun and the nature of its coronal mass ejections, or CMEs and their impact on space-weather.

She is presently leading two science definition teams for future missions in the LWS Program, "Solar Probe" and "Solar Sentinels" and involved in a mission in formulation "Radiation Belt Storm Probes (RBSP)". Solar Probe will be a historic mission, flying into one of the last unexplored regions of the solar system, the Sun's atmosphere or corona, for the first time. Approaching as close as 3 RS above the Sun's surface, Solar Probe will employ a combination of in-situ measurements and imaging to achieve the mission's primary scientific goal: to understand how the Sun's corona is heated and how the solar wind is accelerated. Solar Sentinels, an important mission for NASA's Vision for exploration will help in the understanding and prediction of Solar Energetic Particle (SEPs) and solar eruptive events, and their effects on the interplanetary environments, planets, and other solar system bodies. RBSP's science objectives are to provide understanding of how populations of relativistic electrons and ions in space are formed or changed in response to solar variations. In addition to leading science missions for the LWS program, Dr Guhathakurta also manages a theory, modeling and data analysis program to integrate scientific output, data, and models to generate a comprehensive, systems understanding of Sun-Heliosphere-Planets coupling.

Dr. Guhathakurta is leading an effort in an international initiative known as the "International Living With a Star" (ILWS) consisting of all the space agencies of the world to contribute towards the scientific goal for Space Weather understanding.

A native of India, Dr. Guhathakurta received her Masters in Astrophysics from University of Delhi and Ph.D. in Physics from University of Denver and University of Colorado at Boulder.

Mr. Michael L. Kaiser
STEREO Project Scientist, NASA Goddard Space Flight Center

Michael Keiser Mr. Michael L. Kaiser is a research scientist with the Heliophysics Science Division at NASA Goddard Space Flight Center. He is the Project Scientist for the STEREO Mission and is also the Deputy Principal Investigator of the STEREO WAVES investigation. In addition, he is the Principal Investigator of the WAVES experiment on the NASA Wind spacecraft and on the Voyager Planetary Radio Astronomy (PRA) experiment performed during Voyager's interstellar mission (1989-present). He is a co-investigator on the Ulysses Unified Radio And Plasma Wave experiment (UARP) and the Cassini Radio and Plasma Wave Science (RPWS) team.

Kaiser received his M.S. degree in Astronomy from the University of Maryland in 1971. His research interests include low frequency radio astronomy with particular emphasis on planetary and solar emissions. He is an author on approximately 225 scientific publications and has received the NASA Exceptional Scientific Achievement medal and numerous group achievement awards. He is a member of the American Geophysical Union (AGU), International Union of Radio Science (URSI), European Geophysical Union (EGU), American Astronomical Society/Solar Physics Division and the Institute of Electrical and Electronics Engineers, Inc.
