Professional Experience:

  • Dr. Sonde started his early career working as a scientist in the country's top research institution namely Bhabha Atomic Research Center (BARC). He topped the entire batch of scientists and engineers and was awarded Dr. Homi Bhabha Gold Medal. In the formative part of his career, he was deeply involved in nuclear energy research, developing technology on Heavy Water Plants while interphasing with various scientific, academic and research institutions. He completed his PhD during his stint at Atomic Energy Commission (AEC) in the field of isotope separation simulation sciences.
  • He was invited to join as Executive Director to develop new energy technologies in the country's premier power generator namely National Thermal Power Corporation (NTPC), a mega coal power sector undertaking with over 75,000 MW of power plants to its credit. During his stint there, he worked on starting new activities in clean coal technologies which included low grade heat conversion energy, Integrated Gasification Combined Cycle (IGCC), carbon capture and sequestration and various technologies crucial for energy efficiency and improving the plant performance.
  • His current assignment as Executive Vice President and a member of the Executive Council of Thermal, his main thrust of activities is bringing innovation and enhance knowledge in all the existing technologies within Thermax while also involved in the developing new technologies in the field of energy, environment and water.
