Ashoke Sen

Ashoke Sen

A renowned string theorist

Dr. Ashoke Sen works in the area of string theory. In this framework, the notion of point-particles in particle physics is replaced by one-dimensional objects or ‘strings’ and particle properties like mass, charge, etc., are determined by the vibrational properties of strings. Dr. Sen’s work on ‘strong-weak coupling duality’, which is useful for doing calculations in theoretical physics, won him the first ever ‘Fundamental Physics Prize’. 

Dr. Sen also studied unstable D-branes--a class of strings with endpoints that satisfy certain mathematical conditions, and the developed the famous ‘Sen conjuncture’. His work on rolling tachyons--a hypothetical particle that always moves faster than light--is seminal in the field of string theory with applications in string cosmology--a field that applies equations from string theory to solve the questions of early Universe cosmology.

In recognition of his contributions to the field of physics, Dr. Sen is nominated as a Fellow of the Royal Society. He is also awarded the Padma Shri by the Indian government. Prof. Sen now works at the Harish Chandra Research Institute in Allahabad. 

Doing physics is a lot of fun if you like it…
