Dr Natchimuthuk "Nat" Gopalswamy is an Indian American Solar physicist. He is currently a staff scientist at the Heliophysics Division of NASA’s Goddard Space Flight Center.

Background and scientific career[edit]

Gopalswamy completed a BSc and MSc in physics at the University of Madras in 1975 and 1977, respectively. These were followed by a PhD at the Indian Institute of Science in 1982. He took up research positions at the Indian Institute of Astrophysics, Bengaluru, working on radio observations of the Sun at the Kodaikanal Solar Observatory.[1] In 1985 he moved to the University of Maryland, working on solar radio bursts,[2] before moving to NASA Goddard Space Flight Center in 1997, with a joint research professor position at Catholic University of America. He focused on coronal mass ejections (CMEs) and the relation to solar radio bursts.[3][4][5]

Research interests[edit]

Gopalswamy's primary research interest is solar eruptive phenomenon and their relation to radio bursts and energetic particles.[6] His scientific publications have attracted more than 20,000 citations.[7] His early work focussed on multi-wavelength observations of CMEs.[8][9][10] More recently, his work with the Large-angle and Spectrometric Coronagraph (LASCO) aboard the Solar and Heliospheric Observatory (SOHO) spacecraft is of particular note.[11] He maintains the widely used catalogue of LASCO-observed CMEs.[12][13][14] This long-term dataset has allowed the link between the approximately 11-year solar cycle and CMEs to be better understood.[15][16] During the 2017 solar eclipse, he led a team making spectroscopic measurements of the solar corona.[17] He is the PI of The Balloon-Borne Investigation of Temperature and Speed of Electrons in the Corona (BITSE).[18] He is also the Co-I of Solar Terrestrial Relations Observatory (STEREO) WAVES, and Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) white-light coronagraph COR1 instruments.

Outreach Activities[edit]

Gopalswamy has been conducting numerous outreach activities and have initiated programs to benefit researchers all across the globe. He is the Executive director of the International Space Weather Initiative (ISWI) since 2013. He initiated the SCOSTEP Visiting Scholar (SVS) program in 2015 while president of the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) in 2015.
