Judith Karpen Named AAS 2022 Fellow

Photo of Judith Karpen Judith Karpen has been named a Fellow of the American Astronomical Society. She was honored for her sustained contributions to understanding the formation and dynamics of the solar corona and wind.

Karpen is a research astrophysicist and Chief of the Space Weather Laboratory in the Heliophysics Division. She received her Bachelors of Science in Physics (Honors) from the University of Michigan in 1973 and her PhD in Astronomy from University of Maryland in 1980, followed by a postdoctoral position with the Solar Physics Branch, Space Science Division, NRL. From October 1982 until September 1984, she was a staff scientist with Berkeley Research Associates, working at the Laboratory for Computational Physics, NRL. From October 1984 to July 2008 she was a research physicist in the Solar-Terrestrial Relationships Branch of the Space Science Division of the Naval Research Laboratory. She joined the Space Weather Laboratory in July 2008.

Her primary research interests include analytical and numerical modeling of dynamic solar and heliospheric phenomena, and applications of plasma physics and magnetohydrodynamics to solar and heliospheric activity. Her current research is focused on solar prominences, coronal mass ejections/eruptive flares, and magnetic reconnection.

The Heliophysics Science Division conducts research on the Sun, its extended solar-system environment (the heliosphere), and interactions of Earth, other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace -- Earth's uppermost atmosphere, the ionosphere, and the magnetosphere -- and the changing environmental conditions throughout the coupled heliosphere (solar system weather).

Scientists in the Heliophysics Science Division develop models, spacecraft missions and instruments, and systems to manage and disseminate heliophysical data. They interpret and evaluate data gathered from instruments, draw comparisons with computer simulations and theoretical models, and publish the results. The Division also conducts education and public outreach programs to communicate the excitement and social value of NASA heliophysics.
