Contact Dr Dhiman Chakravarty
Background
Dr. Dhiman Chakravarty is a Postdoctoral Research Associate in the Faculty of Engineering & Applied Sciences at Cranfield University. He obtained his PhD in molecular biology from Bhabha Atomic Research Centre (BARC), Mumbai, India. He has been working as a Scientific Officer at BARC since 2012 and studied both fundamental and applied aspects of stress biology. During his tenure, he elucidated novel aspects of enzymatic antioxidant defence mechanisms in an extremely radiation and desiccation tolerant cyanobacterium. He has also ventured into the application of thermo and alkali tolerant catalase enzyme for peroxide removal in textile industries. Over the years he developed expertise in microbial genome engineering, biotechnology, enzymology, structural biology etc. For his work on oxidative stress biology and potential application of unique enzymes in textile processing, he was conferred with Young Scientist Awards from Indian National Science Academy, National Academy of Science (India) and the Department of Atomic Energy, Government of India.
