Dr S. Chandankumar joined as an Assistant Professor of Mathematics in 2014 and was appointed the Head of the Department of Mathematics and Statistics at RUAS in 2019. In his early years at the university, he was involved in designing curriculum for undergraduate and postgraduate programmes in parallel with preparing lecture notes for various courses. He has taught various courses in Mathematics to undergraduate and graduate students of Science and Engineering. Recently, he was one among the 11 faculty members across the university to receive the coveted award of Exemplary Faculty under the teaching category. He also counsels students and constantly works on various pedagogical methods in teaching. Besides enjoying teaching and research work, he is highly experienced in administration having assumed the responsibilities of Head, Assistant Custodian, Deputy Custodian, BOS Member and BOE member over the years. His research work is focused on discovering new modular equations and theta function identities, most of which are influenced by Srinivasa Ramanujan. At present, he is working extensively on the theory of partitions and also guiding a doctoral student. He has published over 30 research articles which are indexed in MATHSCINET, SCOPUS and SCI journals and also presented more than a dozen research articles in national and international conferences. He has also been invited as resource person for faculty development programs and workshops.

He received his BSc and Master’s degrees in Mathematics from Bangalore University. Soon after, in 2009, he signed up as a Project Fellow for a major research project sanctioned by UGC at the Department of Mathematics, Bangalore University for three years. Alongside, he pursued his doctoral studies at Bangalore University and got his degree in 2013. In his free time, he enjoys playing cricket, reading novels and exploring nature through hiking and sky watching.
