Reference excerpt

Raghavan Varadarajan (born 27 November 1960) is an Indian biophysicist and a professor at the Indian Institute of Science. He is known for his researches in the fields of protein structure and protein folding and his contributions in developing vaccines and drugs for treating a type of fatal influenza and HIV-1. He is a former J. C. Bose National Fellow of the Department of Science and Technology and an elected fellow of the Indian Academy of Sciences and the Indian National Science Academy. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards, in 2002, for his contributions to biological sciences.

Biography Born on 27 November 1960, Raghavan Varadarajan completed his graduate and master's degrees from the Indian Institute of Technology, Kanpur in 1982 and moved to the US for his doctoral studies at Stanford University under the guidance of Steven G. Boxer to secure a PhD. His post-doctoral studies were at Yale University at the laboratory of Frederic M. Richards during 1988–92 and he returned to India to start his academic career at the Indian Institute of Science (IISc) in 1992. Holding the position of a professor of Molecular Biophysics Unit, he heads The Varadarajan Laboratory of IISc which has research interests in the design of HIV-1 and influenza immunogens. He also serves as an honorary professor at Jawaharlal Nehru Centre for Advanced Scientific Research and as the chairman of the scientific board of Theramyt Novobiologics, a Bengaluru-based research platform (which he helped found), engaged in the development of biological drugs.

Legacy Varadarajan's early researches were focused on the interaction of protein molecules and their sequential properties. At Steven G. Boxer's laboratory, he worked on human myoglobin, a hemeprotein, and studied its dielectric properties as well as the redox potential/spectral properties of bound chromophores. Later, during his post-doctoral days at Yale, he researched on the structural and thermodynamic changes associated with cavity formation in proteins. Continuing his researches at IISc, he is known to have developed a new crystallographic and Nuclear magnetic resonance hydrogen exchange protocol for the characterization of disordered states of proteins, and his studies helped in the estimation of the hydrophobic driving force in protein folding. Collaborating with Merck Research Laboratories on behalf of Jawaharlal Nehru Centre for Advanced Scientific Research, his team developed a number of immunogens which have been demonstrated to have positive effect as HIV-1 vaccines and he holds the patent for the invention. Merck have tested the a few vaccines and some of the other proposals are being tested by International AIDS Vaccine Initiative. Varadarajan has published his research findings by way of several articles and his publications have been listed in a number of online article repositories. He served as an investigator of the DBT-IAVI Programme jointly organized by the Department of Biotechnology and International AIDS Vaccine Initiative for the development of HIV vaccines. He has also mentored a number of scholars in their doctoral researches and has conducted seminars on his researches.

Awards and honors Varadarajan received the B. M. Birla Science Award of the B. M. Birla Science Centre in 1998 for his contributions to the study of protein structure and foldings and the Council of Scientific and Industrial Research (CSIR) awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 2002. In 2013, CSIR honored him again with the G. N. Ramachandran Gold Medal for Excellence in Biological Sciences and Technology. He received a number of research fellowships which included the Swarnajayanthi Fellowship for Biological Sciences of the Department of Science and Technology and AIDS-Innovation Grant Award of the National Institutes of Health ( both in 1999), Senior Research Fellowship of Wellcome Trust (2000) and the J. C. Bose National Fellowship of the Department of Science and Technology (2007–12). He is also an elected fellow of the Indian National Science Academy and the Indian Academy of Sciences. In 2024, Varadarajan became a laureate of the Asian Scientist 100 by the Asian Scientist.

Worked examples

Example 1 — a first encounter with Raghavan Varadarajan

Start with the simplest possible case. Write down what Raghavan Varadarajan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Raghavan Varadarajan 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 Raghavan Varadarajan 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 Raghavan Varadarajan

In research: Raghavan Varadarajan appears in biology 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 Raghavan Varadarajan 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: Raghavan Varadarajan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, 20th-century Indian biologists, 20th-century Indian inventors, so understanding it makes those chapters shorter.
In everyday life: Look for Raghavan Varadarajan 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.
