Abhay Ashtekar

Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist who created Ashtekar variables and is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. Ashtekar has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. He is an Evan Pugh Professor Emeritus of Physics and former Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University.

In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a 1974 prediction by Stephen Hawking. Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity." Ashtekar was elected as Member to National Academy of Sciences in May 2016. Provided by Wikipedia
