Rameswar Singh, Ph.D.

Rameswar Singh

Project Scientist — University of California San Diego


Dr. Rameswar Singh conducts research on magnetic fusion energy with particular interests in zonal flows, momentum transport, turbulence, instabilities, and shearing effects in tokamak plasmas.

For his PhD, Dr. Singh studied momentum transport, zonal flows, and microturbulence in tokamaks at the Institute for Plasma Research, Homi Bhabha National Institute (Bhat, Gandhinager, India).

“I’m fascinated by how transport channels become coupled to form a complex transport matrix. This shows how our understanding of tokamak plasmas as self-organized systems is far from complete.”

He has studied the generation of intrinsic rotation, geodesic acoustic modes, and shell models of turbulence. He uses both fluid and gyro-kinetic frameworks in his theoretical approaches.

Dr. Singh’s fellowships include the Postdoctoral Fellowship at the Laboratoire de Physique des Plasmas (Ecole Polytechnique, France) and the Indo-Swiss Joint Research Fellowship (Lausanne, France).

He has presented at numerous scientific conferences—Festival de Théorie (France), Ecole de Physique des Houches (France), IAEA Fusion Energy Conferences (Russia, Korea), and other schools and workshops.

Before joining FAPPG as Project Scientist, Dr. Singh was Postdoctoral Researcher at UC San Diego and the Institute for Plasma Research (Bhat, Gandhinagar, India).

He is a member of the Plasma Science Society of India.
