Girish Nivarti

Associate, Patent Scientist
London

Girish is a patent scientist with an academic background spanning applied mathematics, computational physics, and engineering. His research has focused on advancing the theory of combustion and turbulence, primarily through analytical techniques and scientific computing methods.

Prior to joining EIP, Girish was a research fellow in applied mathematics at the University of Leeds and a research associate in aerospace engineering at the University of Cambridge. At Leeds, Girish formulated a statistical theory and simulation technique for out-of-equilibrium anisotropic fluid systems. In close collaboration with the Brown Theoretical Physics Centre in Providence (USA), he authored a Julia language package applying the simulation technique to study zonal jet evolution in astrophysical turbulence.

At Cambridge, Girish developed analytical models and numerical algorithms to aid simulations of jet engine combustion. He steered a collaboration involving experimentalist groups to resolve disparities in measurements of extremely turbulent Bunsen burner flames, advancing a spectrum-based theory of turbulent flame propagation. His PhD thesis identified a mechanism of flame speed inhibition in high-intensity turbulence using Direct Numerical Simulations on the national high-performance supercomputing cluster.
