Sushil completed his PhD at The University of Queensland in 2011, elucidating the structure-property relations of starch granules.  This was followed by a research fellow position at UQ, examining the starch-plant cell walls interactions.  Sushil joined Monash University (Department of  Chemical Engineering)  in July 2019. 

Sushil currently serves as Editor for the journal Carbohydrate Polymers and on the Editorial Board of the journals Food Hydrocolloids,  Food Chemistry and  Bioactive Carbohydrates and Dietary Fibre.

He also serves as the Chair of The Australasian Grain Science Association (AGSA). AGSA provides a forum for Australasian grain scientists, students, nutritionists and others interested in grain science to advance the knowledge and understanding of grain science and the grain industry.

Sushil carries fundamental and applied research on the structure-property-function-health relationships of food and food ingredients. His stronghold and research interest are in relating plant molecular structures to macroscopic properties relevant to food,  health, and product development. He uses cross-disciplinary approaches from physics, chemistry, biology, and engineering. He uses various in-vitro and in-vivo models to elucidate the fundamental mechanisms beyond the nutritional and processing functionality of food and food ingredients.
