Research Area

My research focuses on advancing theoretical and applied geophysical methods to enhance subsurface exploration and characterization. Key areas of my work include:

  • Edge Enhancement Techniques: I am developing novel theoretical approaches to improve edge detection in geophysical data, enhancing the delineation of subsurface features.
  • 2D and 3D Potential Field Modeling and Inversion: My work involves sophisticated modeling and inversion techniques for gravity and magnetic data to refine subsurface imaging and geological interpretations.
  • Curie Depth Analysis: I analyze the depth to the Curie point to assess the thermal and magnetic properties of the Earth's crust, providing insights into geothermal gradients and magmatic processes.
  • gPhone Gravity Data Analysis: I utilize advanced gPhone technology to analyze gravity data, improving the accuracy of gravitational anomaly detection and interpretation.
  • Global Tectonic Studies: Additionally, I specialize in the tectonic analysis of global geological provinces using satellite-based gravity and magnetic data. My research spans diverse regions, including Central India, Singhbhum and Rajasthan cratons, the Central Indian Ocean, the Arabian Sea, and the Bay of Bengal, contributing to a comprehensive understanding of global geological structures and processes.
