Reference excerpt

Sudip Chattopadhyay (born 1 August 1960) is an Indian developmental biologist, biotechnologist and the dean of research and consultancy at the National Institute of Technology, Durgapur. Known for his studies on the molecular basis of light-controlled plant growth and development, Chattopadhyay is a J. C. Bose National Fellow of the Science and Engineering Research Board (SERB) and an elected fellow of all the three major Indian science academies namely Indian National Science Academy, Indian Academy of Sciences and National Academy of Sciences, India. The Department of Biotechnology of the Government of India awarded him the National Bioscience Award for Career Development, one of the highest Indian science awards, for his contributions to biosciences in 2005.

Biography

Born on 1 August 1960 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. 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. 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. Chattopadhyay resides in Salt Lake City, a satellite town in West Bengal.

Legacy

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. 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. His studies have been documented by way of a number of articles and the online article repository of the Indian Academy of Sciences has listed 22 of them. He has mentored several doctoral scholars and has delivered invited or plenary speeches at seminars and conferences.

Awards and honors Chattopadhyay, who holds the J. C. Bose National Fellowship of the Science and Engineering Research Board, received the Merit Award of Kalyani University in 1986 for academic excellence. The Department of Biotechnology of the Government of India awarded him the National Bioscience Award for Career Development, one of the highest Indian science awards in 2005. The National Academy of Sciences, India elected him as a fellow in 2006 and he became a member of Guha Research Conference in 2007, the same year as he received the Ramanna fellowship of the Department of Science and Technology. He received the elected fellowships of the two academies in 2009, those of the Indian Academy of Sciences and the Indian National Science Academy. A year later, the West Bengal Academy of Science and Technology elected him as a fellow.

Worked examples

Example 1 — a first encounter with Sudip Chattopadhyay

Start with the simplest possible case. Write down what Sudip Chattopadhyay claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sudip Chattopadhyay before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sudip Chattopadhyay ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sudip Chattopadhyay

In research: Sudip Chattopadhyay appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sudip Chattopadhyay in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sudip Chattopadhyay is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, Academic staff of the National Institute of Technology, Durgapur, Developmental biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Sudip Chattopadhyay outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
