Dr. Ram Singh

No One Can Walk Out From His/Her Own Story

I am currently working as a Scientist (Assistant Professor) at the Indian Institute of Geomagnetism (IIG), Mumbai, India, where my research focuses on understanding the electrodynamics and variability of the equatorial and low-latitude ionosphere under both quiet and disturbed geomagnetic conditions. My research focuses on understanding the coupling between the solar wind, magnetosphere, ionosphere, and atmosphere, and how these interactions influence the near-Earth space environment.
Prior to joining IIG, I worked as a Postdoctoral Researcher at the Jicamarca Radio Observatory (JRO), Instituto Geofísico del Peru (IGP), home to the world-renowned Jicamarca Incoherent Scatter Radar (ISR), the largest and most powerful equatorial incoherent scatter radar in the world (https://www.igp.gob.pe/observatorios/radio-observatorio-jicamarca/; https://en.wikipedia.org/wiki/Jicamarca_Radio_Observatory )
I work on ionospheric electrodynamics, plasma irregularities, and radio wave propagation in the equatorial and low-latitude ionosphere. Using observations from the Jicamarca Incoherent Scatter Radar (ISR), GNSS receivers, ionosondes, magnetometers, and satellite missions, I investigate the physical processes that drive ionospheric variability and affect communication and navigation systems.
A key component of my research involves the use of oblique sounding techniques to investigate regional ionospheric structures and dynamics.
