Major Professional Contributions:

Sujith showed that the stable operation of a turbulent combustor corresponds to a chaotic state, and it transitions via intermittency to limit cycle oscillations (unstable state). He showed that the combustion noise that occurs during stable operation has a multifractal nature, which is lost at the onset of thermoacoustic instability. He showed that combustion noise can be topologically represented as a scale-free network which transitions to a regular network at the onset of instability. Sujith developed a unified theory for thermoacoustic instability and blowout. These paradigm shifts helped Sujith develop precursors for the onset of thermoacoustic instability and blowout. He discovered the non-normal nature of thermoacoustic systems..
