Reference excerpt

Professor Ramakrishna Vijayacharya Hosur is an Indian biophysical scientist, known for his expertise in the areas of nuclear magnetic resonance and molecular biophysics. The Government of India honoured him, in 2014, by awarding him the Padma Shri, the fourth highest civilian award, for his contributions to the fields of science and technology.

Biography

Ramakrishna Vijayacharya Hosur was born in the South Indian state of Karnataka on 16 May 1953. He graduated with chemistry, Physics and Maths as optional subjects in 1971 securing the 5th rank from Karnatak University and did his masters in Chemistry, MSc, from the Indian Institute of Technology, Mumbai (IIT-B) with third rank, in 1973. This was followed by a PhD from the Tata Institute of Fundamental Research (TIFR), Mumbai in 1978. Hosur started his career by joining TIFR as a Research Associate in August 1978 and was promoted as a TIFR Fellow in 1980, a status he maintained till 1986. In between, in 1981, he took a long leave of two years from the institute and did post doctoral research at the ETH Zurich where he worked in the company of Professor Richard R. Ernst and Professor Kurt Wuthrich, who would eventually win Nobel Prize in 1991 and 2002 respectively. In 1986, Hosur rejoined TIFR in the post of the Reader. Five years later, he was promoted as the Associate Professor and then as the Professor in 1996. Hosur is the Senior Professor at the Tata Institute since 2003 in the Department of Chemical Sciences. Professor Hosur has also worked at the Columbia University, New York, at Professor D. J. Patel's laboratory for three months (20 August - 20 November) in 1988. During his TIFR career, Hosur is reported to have been active in the administration of the institute by holding the chair of the Department of Chemical Sciences, Advisory Committee for Administration and Finance, and the Standing Committee on Administration for various tenures. He was also the Vigilance Officer of the institute from 2002 till 2004 and is the Convener for the National Facility for High Field Nuclear Magnetic Resonance since 2002 till date. Ramakrishna Hosur is married and has two children and the family lives in Mumbai.

Legacy Hosur has taught at the Tata Institute of Fundamental Research, Indian Institute of Technology Mumbai and National Institute of Technology Rourkela on nuclear magnetic resonance and is credited with pioneering research on biomolecular nuclear magnetic resonance, molecular biophysics, and biophysical chemistry at these institutions. The efforts of Dr. Hosur has led to the discovery of new structural motifs in quadruplex DNA structures; A-tetrad, T-tetrad and C-tetrad and the development of new multidimensional NMR pulse sequences. He is reported to have explained the folding hierarchy in HIV-1 protease, the native state energy landscape, and structural and dynamic characteristics of SUMO-1 protein along the equilibrium folding pathways and also shown experimentally that the progress of the native contacts is not monotonous. Hosur is reported to have developed a new NMR based theoretical model which is said to be of assistance in the structural studies on proteases. He has also developed scaling techniques for the enhancement of resolution and sensitivity and proposed what Indian Academy of Sciences quotes as:a pH switch mechanism for cargo trafficking by DLC8 protein inside living cells.

Hosur has delivered keynote addresses at various international conferences and has lectured at many international institutions. He has also taken part in organizing many international conferences. He has also guided many students in their doctoral research. Hosur is credited with 3 books of which two as editor, three book reviews, three technical reports and over 150 articles, published in national and international peer reviewed journals. The US National Library of Medicine has listed 112 articles by Dr. Hosur in their online repository.

Positions Hosur is life member of Indian Biophysical Society, Indian Science Congress Association, Society for Biological Chemists, India and the Chemical Research Society of India. He is a member of the International Society of Magnetic Resonance, the Society for Cancer Research and Communication, Mumbai and American Chemical Society. He has led, in the capacity of the President, such organizations as Indian Biophysical Society, New Biology Section of the Indian Science Congress, and the National Magnetic Resonance Society. He has also served as the council member of Chemical Research Society of India, ICMRBS, Centre for Biomedical Magnetic Resonance, Research Council of IICB, Kolkata, INSA, NASI, and ISCA. Hosur, founder and life member of the National Magnetic Resonance Society, is a reviewer for international journals such as International Journal of Quantum Chemistry, Journal of Biomolecular NMR and Biochemistry USA and a reviewer for proposals of grant of international funding agencies viz. Wellcome Trust, UK, Erwin Schrodinger Fellowship, Indo Swiss and Indo French collaborative projects and Austrian Science Foundation. He is also an examiner for the award of PhD at the Indian Institutes of Technology, Bangalore, Mumbai and Delhi. Prof. Hosur has been appointed as a distinguished visiting professor in the Department of Biosciences and Bioengineering in IIT Bombay from 4 September 2018.

Worked examples

Example 1 — a first encounter with Ramakrishna V. Hosur

Start with the simplest possible case. Write down what Ramakrishna V. Hosur claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Ramakrishna V. Hosur 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 Ramakrishna V. Hosur 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 Ramakrishna V. Hosur

In research: Ramakrishna V. Hosur appears in physics 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 Ramakrishna V. Hosur 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: Ramakrishna V. Hosur is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, 20th-century Indian biologists, 20th-century Indian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Ramakrishna V. Hosur 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.
