RESEARCH TECHNIQUES

I am experienced and competent in the collection of field data on Magnetotelluric, Radio-Magnetotelluric, Transient Electromagnetic, Direct Current Resistivity and Seismic Refraction Methods.  I am also experienced on data analyses on magnetotelluric methods. During my education life, I have developed many 2-D modelling (Direct current resistivity, Magnetotelluric, Seismic Refraction and Seismic Reflection) and inversion (Direct current resistivity, Magnetotelluric, Seismic Refraction) algorithm. My main interest is about joint inversion of multiple datasets and magnetotelluric field investigations.
