Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology.[2] He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking.[3] 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."[4] Ashtekar was elected as Member to National Academy of Sciences in May 2016.[5]

Biography

Abhay Ashtekar grew up in several cities, including Mumbai, in the state of Maharashtra, India. After completing his undergraduate education in India, Ashtekar enrolled in the graduate program for gravitation at the University of Texas at Austin.[1] He went on to complete his PhD at the University of Chicago under the supervision of Robert Geroch in 1978 and held several appointments at Oxford, Paris, Syracuse before settling at Penn State.[6]

He married Christine Clarke in 1986[7] and the two have a son, Neil Ashtekar.

Religious views

Abhay Ashtekar is an atheist, though he enjoys reading on Indian and other eastern philosophy, namely the Tao and the Zen traditions. Furthermore, he claims to be inspired from the Bhagwat Gita as regards his attitude towards work.[7]
