Born on 1 August 1960[2] in the Indian state of West Bengal, Sudip Chattopadhyay completed a BSc honors degree in chemistry from the University of Burdwan and obtained an MSc in biochemistry from the University of Kalyani in 1986.[3] Subsequently, he did his doctoral studies on the role of regulatory genes involved in carbohydrate metabolism at the Bose Institute under the guidance of Sudhamoy Ghosh which earned him a PhD from the University of Calcutta.[4] Moving to the US in 1993, he joined the University of Michigan as a research associate but later shifted to Yale University and Purdue University where he completed the post-doctoral work. Returning to India in 2000, he joined the National Institute of Plant Genome Research, New Delhi as a professor. He was holding the grade of staff scientist IV when he joined the National Institute of Technology, Durgapur in 2009 as a professor where he serves as a professor at the department of biotechnology and as the dean of research and consultancy.[5]
Chattopadhyay resides in Salt Lake City, a satellite town in West Bengal.[6]
During his post-doctoral years in the US, Chattopadhyay worked on the regulatory switch of seedling development in plant and propounded the theory that the first transcription factor of light signaling pathways which interacted with COP1 was HY5.[3] Later, he studied the role of light in plant growth and development and its molecular basis. The team led by him was successful in synthesizing Z-box binding transcription factors such as ZBF1, ZBF2 and ZBF3 and regulatory proteins like SHW1 and EHY5, all of which have significant role in plant development from seedling stage to flowering. They have also been successful in demonstrating the correlation between Z-box binding factors and other transcription factors namely HY5, HYH, COP1 and SPA1. Their work has resulted in the generation of ZBF1 over-expresser transgenic tomato plants and investigations are on regarding the biotechnological potential of the findings in crop development.[3] His studies have been documented by way of a number of articles[note 1] and the online article repository of the Indian Academy of Sciences has listed 22 of them.[7] He has mentored several doctoral scholars and has delivered invited or plenary speeches at seminars and conferences.[8]
