Prajwal M.L.


I received my Bachelor's degree in mechanical engineering in 2018. At college, I was involved with the SAE Collegiate Club in building go-karts, and ATV's for amateur racing circuits. I handled the task of researching and procuring materials for building strong and durable chassis for the cars, and later led the Innovations team. My capstone project was on devising low-cost nanomaterials based thermoeletric modules for lower temperatures. Currently, I am interning with Prof. Chandan Srivastava's lab at the Indian Institute of Science (IISc), Bangalore. My projects here tend to focus on the use of graphene and graphene oxide in thin film depositions for superior electrochemical and corrosion resistance properties.
