Over
the past two decades, Dr. Nat Gopalswamy has been engaged in solving problems
in solar and solar terrestrial physics using data from various large radio
telescopes and space missions, particularly coronal mass ejections. 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 analysis of Yohkoh,
Notable
achievements:
·Established
the Center for Solar Physics and Space Weather at the Catholic University
of America to train students and Post-doctoral fellows in the physics of Sun-Earth
connections.
·Created
a "Coordinated Data Analysis (CDAW)
·Conducted
a CDAW workshops in 1999 followed by an international conference in 2000,
which resulted in the publication of more than two dozen scientific papers
in the Geophysical Research Letters (May 2000) and Journal of Geophysical
Research (October 2001).
Some
of the notable discoveries, in which Dr. Gopalswamy was a lead-author:
·First
detection of radio CME (1992)
·the transient
microwave brightenings (1995)
