Prakash Prashanth

Research Scientist and LAE Executive Officer


I hail from Chennai, a tropical, bustling metropolitan city in southern India. My childhood fascination with flight grew into an interest for aerospace engineering during an exchange semester at École Centrale Paris. I completed my Bachelor’s Degree in Mechanical Engineering from the National University of Singapore in 2016 and completed my Master’s and PhD in the Laboratory for Aviation and the Environment in 2018 and 2022.



My research vision is to help create a vibrant and inclusive aviation system having near-zero environmental impact. I work in the intersection of technolgy and policy to enable such a near-zero impact system. The growing environmental impact of aviation poses an existential challenge for the sector, especially since other sectors have clear paths to decarbonise. I believe that an aviation industry with near-zero environmental impact is not only feasible but essential to ensure the sustained growth of aviation’s societal and economic benefits.

My research interests are in the areas of advanced propulsion systems, aircraft-propulsion integration, emissions control technology for gas turbine engines to develop systems level solutions to aviation environmental impacts. I teach undergraduate course on aerospace propulsion and a graduate level course on aviation environmental impacts.
