Centenary Indian-American statistician and scientist Kalyampudi Radhakrishna Rao has been awarded the Nobel Prize in Mathematics. He is getting the 2023 'International Prize in Statistics' or 'Nobel of Mathematics'.

The prize worth 80,000 dollars will be handed over to CR Rao at the World Statistics Congress organized by the International Statistical Institute in Ontario, Canada next July.

According to the International Statistics Prize Foundation, Rao is being awarded for significant contributions to the application and application of statistics in medical research and other fields.

Originally from Karnataka, Rao is famous for three fundamental studies published in 1945. With which this Bengal is connected. The research was published in the Bulletin of the Calcutta Mathematical Society. In fact, Rao, the son of a Telugu family, completed his schooling in Andhra Pradesh and came to Calcutta for higher education. He earned an MA in Statistics from Calcutta University.

One of Rao's three fundamental studies is the 'Kramer-Rao Lower Bound'. This theory establishes the effectiveness of the hypothesis. The second is known as 'Rao-Blackwell Theorem' and the third is known as 'Information Geometry'. 'Information geometry' has been used to explain the Big Bang theory as well as to observe the Higgs boson particle. Chairman of the International Statistics Prize Foundation, Guy Nason, said, 'We celebrate CR Rao's monumental work by awarding this prize. Works that not only revolutionized the statistical thought of his time, but also had a profound impact on the scientific consciousness as a whole.'

CR Rao has taught in several universities around the world including India. He has received numerous honors and awards in his long life and is currently a researcher at the University of Buffalo and Emeritus Professor at Pennsylvania State University.
