Education and career
Mathai was born in Arakulam near Palai in the Idukki district of Kerala, India as the eldest son of Aley and Arakaparampil Mathai. After completing his high school education in 1953 from St. Thomas High School, Palai, with record marks he joined St. Thomas College, Palai, and obtained his B Sc. degree in mathematics in 1957. In 1959 he completed his master's degree in statistics from University of Kerala, Thiruvananthapuram, Kerala, India, with first class, first rank and gold medal. Then he joined St. Thomas College, Palai, University of Kerala, as a lecturer in Statistics and served there until 1961. He obtained Canadian Commonwealth scholarship in 1961 and went to University of Toronto, Canada, for completing his MA degree in mathematics in 1962. He received his PhD in mathematics from the University of Toronto in 1964 under the supervision of Ralph Wormleighton.[1] Mathai then joined McGill University as an assistant professor and was promoted to an associate professor there in 1968. He became a full professor at McGill in 1979 and served the department of mathematics and statistics until 2000. From 2000 onwards he was an emeritus professor of McGill University.
Honors and awards
In 1998, Mathai was awarded the Founder recognition award from the Statistical Society of Canada, which he was heavily involved in its foundation.[3][4] He is a fellow of the National Academy of Sciences, India[5] and a fellow of the Institute of Mathematical Statistics.[6]
