Mathematical Pioneer C.R. Rao Receives International Prize in Statistics at 102

New Delhi  10 June(VNI) Calyampudi Radhakrishna Rao, a renowned mathematician of Indian-American origin, has been bestowed with the prestigious International Prize in Statistics at the impressive age of 102. Widely acknowledged as a trailblazing statistician, Rao's influential contributions have left an indelible impression on the field of statistics and continue to shape mathematical and scientific research on a global scale.

Born in 1920 into a Telugu family in Hadagali, Karnataka, Rao embarked on his academic journey at Andhra University, where he completed his MSc in mathematics. His pursuit of knowledge took him to Calcutta University, where he earned an MA in statistics in 1943. Seeking further academic growth, Rao traveled to the United Kingdom to pursue a PhD, working under the guidance of Sir Ronald A. Fisher. In 1965, he attained a DSc degree from King's College at Cambridge University, solidifying his expertise and scholarly accomplishments.

Rao's illustrious and multifaceted journey has traversed diverse domains within the intricate realm of statistics. With his groundbreaking work, he has firmly established himself as a foremost pioneer in the realm of modern statistics. Noteworthy among his achievements are the creation of revolutionary statistical techniques that have propelled the field forward. The Cramer-Rao inequality, a bedrock principle for bounding the variance of unbiased estimators, stands as a testament to his ingenuity. Moreover, the transformative Rao-Blackwell theorem, allowing the metamorphosis of estimates into optimal estimations, further exemplifies his profound contributions.

Beyond theoretical pursuits, Rao's exceptional expertise extends to practical applications in an expansive array of fields. His far-reaching influence can be witnessed in domains as diverse as genetics, ecology, and the social sciences. Moreover, his pivotal role in the advancement of sample survey methods in India reflects his unwavering dedication to making tangible and pragmatic contributions to the realm of statistical practice.

Rao's academic journey has been punctuated by numerous accolades and honors, underscoring the profound impact of his work. In 1968, he was bestowed with the esteemed title of Padma Bhushan, followed by the Padma Vibhushan in 2001, both prestigious civilian awards in India. Recognizing his exceptional contributions, President George W. Bush presented Rao with the National Medal of Science in 2002. The International Prize in Statistics, a distinction often regarded as equivalent to the Nobel Prize in the field.

Currently, Rao holds the esteemed position of professor emeritus at Pennsylvania State University and serves as a Research Professor at the University at Buffalo. His enduring legacy as a visionary statistician, mathematician, and researcher continues to inspire generations and pave the way for further advancements in the field of statistics.
