Venki Ramakrishnan

Venki Ramakrishnan is a structural biologist renowned for his pioneering work in determining the atomic structure of the ribosome, a fundamental molecular machine for protein synthesis. His research, which elegantly combined X-ray crystallography with biochemistry, provided profound insights into how antibiotics target bacterial ribosomes. For this achievement, he was jointly awarded the Nobel Prize in Chemistry in 2009 with Thomas A. Steitz and Ada E. Yonath. He has held significant leadership positions in the global scientific community, including as President of the Royal Society from 2015 to 2020.

Early life and education

Venkatraman Ramakrishnan was born in Chidambaram, Tamil Nadu, and spent his early years in Vadodara, Gujarat. His father, C. V. Ramakrishnan, was a professor of biochemistry at Maharaja Sayajirao University of Baroda, which initially fostered his scientific curiosity. He completed his undergraduate degree in physics at the same university before moving to the United States for graduate studies. He earned his Ph.D. in physics from Ohio University in 1976, working under the supervision of Tomoyasu Tanaka, before transitioning into biology through postdoctoral research at Yale University and the University of California, San Diego.

Career and research

Ramakrishnan's independent research career began at Brookhaven National Laboratory, where he started applying neutron scattering techniques to biological problems. He later moved to the University of Utah as a professor of biochemistry, solidifying his focus on the ribosome. A pivotal career shift occurred in 1999 when he joined the world-renowned MRC Laboratory of Molecular Biology in Cambridge, England. There, his group engaged in a highly competitive international race to solve the high-resolution structure of the 30S ribosomal subunit, a complex of ribosomal RNA and proteins. His team's success, published in the journal *Nature*, was a landmark in structural biology.

Nobel Prize in Chemistry

In 2009, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry jointly to Ramakrishnan, Thomas A. Steitz, and Ada E. Yonath "for studies of the structure and function of the ribosome." The academy highlighted their use of X-ray crystallography to map the atomic positions within the ribosome, revealing the detailed mechanism of protein biosynthesis. This work explained how the ribosome reads messenger RNA and catalyzes the formation of peptide bonds, and crucially, how various antibiotics like streptomycin and tetracycline bind to and inhibit bacterial ribosomes, guiding the design of new drugs.

Leadership roles and honors

Following his Nobel Prize, Ramakrishnan took on prominent institutional leadership roles. He served as President of the Royal Society from 2015 to 2020, succeeding Paul Nurse and preceding Adrian Smith. In this capacity, he advocated for international scientific collaboration, evidence-based policy, and science education. His numerous honors include being knighted in the 2012 New Year Honours, receiving the Copley Medal in 2023, and being appointed to the Order of Merit by Queen Elizabeth II in 2022. He is also a foreign member of the U.S. National Academy of Sciences and an honorary fellow of several institutions, including Trinity College, Cambridge.

Personal life and publications

He is married to author and illustrator Vera Rosenberry, and they have one son. Beyond his scientific papers, Ramakrishnan authored the acclaimed book *Gene Machine: The Race to Decipher the Secrets of the Ribosome*, which provides a personal narrative of the scientific rivalry and collaboration behind the Nobel-winning discovery. He has been a frequent commentator on issues ranging from Brexit's impact on science to public trust in expertise, contributing articles to publications like *The Guardian* and delivering keynotes such as the BBC Reith Lectures in 2020.
