Background

Gopakumar was born in 1967 to Jaishree and G. Gopakumar in Kolkata.^{[citation needed]} His family hails from the southern Indian state of Kerala.^[2] He has the distinction of securing All Indian Rank 1 in the examination for IIT-JEE in 1987.^[3]

Gopakumar obtained his integrated M.Sc. degree in physics from the prestigious IIT Kanpur in 1992. He completed his Ph.D. from Princeton University in 1997 under the supervision of David Gross. After a few years as a research associate at Harvard University, he joined HRI in 2001. He was also a visiting fellow at the Institute for Advanced Study, Princeton, New Jersey from 2001 to 2004.^[4]

He is married to Rukmini Dey, a Professor of Mathematical Physics and Geometry at ICTS-TIFR.^[5]

Research

Gopakumar is a string theorist. Earlier on in his career, his research was primarily focused on large N gauge theories with David Gross, noncommutative gauge theories with Andrew Strominger and Shiraz Minwalla, and topological string theory and gauge/geometry correspondence with Cumrun Vafa and is particularly known for proposing the Gopakumar–Vafa duality and Gopakumar–Vafa invariants.^[6]

Later, his work focused on attempts to derive the AdS/CFT correspondence, and on minimal model holography (with Matthias Gaberdiel). In recent years, he has made important contributions to higher spin theories and their connections with string theory (with Matthias Gaberdiel). ^{[citation needed]}He has also recently worked on the Conformal bootstrap.
