Jyotiprasad Medhi  was a professor of statistics at Gauhati University and Institute of Advanced Study in Science and Technology.

Work and education
Medhi started his schooling in Dibrugarh and in 1940 he passed matriculation from Dibrugarh Government High School. After matriculation, he did his graduate studies in Cotton College, Guwahati in 1946 and was a gold medalist in BSc with Honours in mathematics. There he received the Sudmerson Gold Medal and Rajanikant Barat Gold Medal. Medhi did his MSc in Pure Mathematics from Calcutta University, and got the Debendra Nath Gangopadhaya Gold medal for record marks obtained and the Post graduate First class first gold medal in 1948. In 1952, he took a loan of ten thousand rupees from Govt of Assam and moved to England to pursue Master of Statistics (MStat) from the University of Manchester and completed in 1954. He worked with M S Bartlett in the University of Manchester in 1955 on the topic 'Time Series Analysis'. Thereon Medhi moved to France to complete his DSc at the University of Paris in 1956 under the supervision of Robert Fortet, while Georges Darmois and Daniel Dugué served on his thesis examination committee. He had also taken a diploma in French Language with mention 'Honorable'. Its worthy to mention that he had written his doctoral thesis in French Language.

Medhi joined as a lecturer of statistics at Cotton University erstwhile Cotton College, Guwahati in 1948. However, in the same year Gauhati University was established and he was invited to work as professor in Gauhati University.

Medhi returned to Gauhati University where he became a professor and was the head of the department of statistics till he retired in 1985. Earlier in Gauhati University, both mathematics and statistics were in a common department, however, under the able leadership of Prof Medhi, statistics became a full-fledged individual department.
