Dr Vimalnath Selvaraj

Postdoctoral Research Associate

INTEREST
I am passionate about research and development of circular economy based sustainable inventions covering both biological and chemical processes. My research focuses on recycling of spent batteries to manufacturing new batteries. With my interdisciplinary background combining chemical engineering, industrial and environmental biotechnology, I am very much interested in leveraging the full potential of my subject knowledge, skills, research experience in academia, industry, and scale-up expertise for expanding my eco-friendly research portfolio to hydrogen production, desalination, CO2 capture and conversion into value-added products, thus contribute to sustainability and circular economy agenda.
