Research Interest:

  • Astrophysics: Strength of Relativistic Jets Correlated with Size of Black Holes and Accretion Disks in Active Galactic Nuclei (AGN) using data from the COSMOS Survey.
  • Heliophysics: Interactions Between Solar Events, Coronal Mass Ejections (CME), the Solar Wind and the Earth's Ionosphere and Magnetosphere.
  • Atmospheric Science: Distribution and transport of tropospheric ozone in the Northeast Regions using ground, balloon and satellite data.

Current Research: My current research involves the study of solar variability (short-term and long-term) & heliospheric disturbances and the study of solar dynamo, magnetohydrodynamic effects and magnetic reconnection on solar activity and correlate to properties of solar wind (SW) and coronal mass ejections (CMEs).
