My research interests are in Geophysical inverse theory and its application in the interpretation of different data sets. My main focus is in developing practical algorithms for inverting ( Individual or Joint inversion ) DC, Electromagnetic (Magnetotellurics /VLF), Gravity and Magnetic data to reconstruct 2D/3D distribution of physical properties.
