Over the past two decades, Dr. Gopalswamy has been engaged in solving problems in solar and solar terrestrial physics using data from various large radio telescopes and space missions. In particular, he is interested in coronal mass ejections and their impact on Earth and on the heliosphere in the form of magnetic storms and particle radiation. He has considerable expertise in the analysis of multi-wavelength data (X-ray, EUV, optical and radio). In the recent years, he has been extensively involved in the analys is of Yohkoh, SOHO, STEREO, Wind and ACE data in conjunction with radio and optical images obtained by ground based instruments. Dr. Gopalswamy’s research interests include solar terrestrial physics and solar radio astronomy. He is a member of the SOHO and STEREO teams engaged in studying coronal mass ejections using coronagraph and in-situ data from Wind and ACE. He has authored or co-authored more than 400 papers.

Some of the notable discoveries of Dr. Gopalswamy: radio CME (1992), Umbral oscillations in microwaves (1993), transient microwave brightenings (1995), three-part CME using non-coronagraphic observations (1996), Effective interplanetary acceleration of CMEs (2000), Colliding CMEs (2001), High-latitude CMEs and solar polarity reversal (2003), Empirical shock arrival model (2005), High-speed radio-quiet CMEs (2007), CME Deflection by coronal holes (2009), Radio-quiet interplanetary shocks (2010), Heliospheric magnetic field from white-light shock structure (2011), Relation between polar magnetic field strength and microwave brightness (2012), Latitudinal connectivity in GLE events (2013), Anomalous expansion of CMEs in Solar Cycle 24 (2014).

Dr. Gopalswamy is actively involved in NASA’s Living with a Star (LWS) program in organizing the Coordinated Data Analysis Workshops (commonly known as CDAWs). He was an associate editor of Journal of Geophysical Research (Space Physics) and Geophysical Research Letters. Dr. Gopalswamy served as the Workshop Coordinator for the US National Science Foundation’s SHINE program and a member of its steering committee (2003-2005). He is also the International Coordinator for the International Heliophysical Year (IHY) 2007 program and a member of its international executive committee. Currently, he serves as the director of international coordination for the International Space Weather Initiative (ISWI). He also plays organizational roles in IAU, SCOSTEP, CAWSES, and VarSITI. He is the current President of SCOSTEP (2011- ). He has served as a member of NASA’s 2005 Sun-Solar System Connection Roadmap committee. He is also the director of the Coordinated Data Analysis Center at GSFC.
