[edit] Academic career

Choudum hails from Bellari. He completed his M.A. in mathematics from the Karnataka University, Dharwar and went to I. I. T Chennai to get his Ph.D. (1975) (Some Analysis, Synthesis and Enumeration Problem in Graph Theory) under the guidance of Professor KR Parthasarathy. From there, he came to University of Mumbai to work with S. S. Shrikhande, S. B. Rao and Vasanti N. Bhat-Nayak. Prior to joining the computer science department at I. I. T, Chennai, he was with the department of mathematics Madurai Kamaraj University. While at Madurai, he visited University of Reading to work with Crispin Nash-Williams. Choudum was chairman of the department of mathematics, I. I. T, Chennai. He has guided students for their Ph.D.s in graph theory.
