Academic Info

- Research Interests:

I am specialized on a branch of geophysics, namely “geomagnetism” and have been working on varieties of subjects under this topic. These are:

(i) Internal (main) geomagnetic field studies (in particular, westward drift of the non-dipole field),

(ii) External geomagnetic field studies (Magnetic effects of solar eclipses on the ionosphere, Solar and Lunar geomagnetic variations),

(iii) Electromagnetic induction in the crust and upper mantle (These include applications of magnetotelluric method on active/passive faults, volcanoes, geothermal systems and ocean bottom EM studies).
