Nikhil Srivastava, a young Indian mathematician, has been declared the joint winner of the prestigious Michael and Sheila Held Award of 2021, along with two others, for solving long-standing unanswered questions on the Kadison-Singer problem and the Ramanujan graph.


The National Academy of Sciences said in a statement that Nikhil Srivastava of the University of California, Berkeley, Adam Marcus of Ecol Polytechnic Federal de Losane (EPFL), and Daniel Alan Spielman of Yale University would be awarded the 'Michael and Sheila Held Prize' of 2021. The award consists of a medal and the US $ 100,000.


Srivastava, Marcus, and Spielman have solved long-unanswered questions involving the Kadison – Singer problem and the Ramanujan graph. In this process, a deep new relationship between linear algebra, polynomial geometry, and graph theory is explored.


Srivastava is currently an associate professor of mathematics at the University of California.
