Margaret Kivelson

Margaret Galland Kivelson (* 1928 ) is an American astrophysicist and professor at the University of California, Los Angeles . She is a specialist in the magnetospheres of Earth , Jupiter and Saturn as well as the interaction of plasma with planets and moons in general .

Scientific career

In 1950 Kivelson received his bachelor's degree from Radcliffe College in Cambridge (Massachusetts) , a year later his master's and his doctorate in 1957 at the same college that is now part of Harvard University . At the time, less than two percent of all physics doctoral students were female.

From 1955 Kivelson was employed by the Rand Corporation , a think tank , and worked in the field of plasma physics . In 1967 she got a position at the Institute of Geophysics and Planetary Physics at the University of California in Los Angeles. In 1971, Kivelson became Adjunct Assistant Professor there and at the same time gave up her position at RAND. Soon after, she was involved in analyzing the data provided by the Pioneer 10 and Pioneer 11 probes about Jupiter's magnetic field. From then on, she dealt with the magnetospheres of different planets and in 1976 suggested equipping the planned Jupiter mission Galileo with magnetometers in order to gain further knowledge about the magnetosphere of Jupiter. In addition, she postulated that not only - as assumed until then - some planets, but also some moons have an internal magnetic field .

In 1977, Kivelson was appointed to a professorship in the Department of Earth and Space Science . From 1978 to 1981 Kivelson was initially deputy, the following three years chairman of this department. At the same time, she received a professorship at the Institute of Geophysics and Planetary Physics from 1983 . Kivelson has held both positions to this day (2010).

After Galileo was launched with great delay in 1989, Kivelson was significantly involved in important discoveries in connection with the mission in the 1990s: on the one hand, the discovery and measurement of the internal magnetic field of Jupiter's moon Ganymede , on the other hand, the discovery and assessment of the internal magnetic field of the moon Io . This confirmed their assumptions published in 1979 about the internal magnetic field of moons. Kivelson also took part in this mission to research the magnetic field of the asteroid Gaspra .

Kivelson is currently working on the Saturn Cassini mission and NASA's THEMIS project. She is also involved in the cluster program, a cooperation between NASA and ESA to research the Earth's magnetosphere .

Awards

For her work in the Galileo project, Kivelson received the NASA Group Achievement Award in 1995 and 1996 . In 1998 she was admitted to the American Academy of Arts and Sciences , a year later to the National Academy of Sciences, and in 2005 to the American Philosophical Society . In 1989 she became a Fellow of the American Association for the Advancement of Science and in 2001 of the American Physical Society . For 2019 she was awarded the Jean Dominique Cassini Medal of the European Geosciences Union and the Gold Medal of the Royal Astronomical Society . In 2020, Kivelson was elected to the Royal Society as a foreign member .

Private life

Margaret Kivelson was married to the chemist Daniel Kivelson , who died in 2003 and was also a professor at the University of California. From this marriage she has a daughter and a son, Steven Kivelson , who has been professor of physics at Stanford University since 2004 after holding a professorship at the University of California .
