Biographic Sketch:
Dr A. Chandrashekaran, Assistant Professor of Mathematics at the School of Mathematics and Computer Sciences, Central University of Tamil Nadu (CUTN), Thiruvarur, since March 2012. He had his PhD from the Indian Institute of Technology Madras Chennai in 2010, followed by a DST - Research Associateship at C R Rao Advanced Institute of Mathematics Statistics and Computer Sciences, Hyderabad. He received his BSc and MSc in Mathematics from Madurai Kamaraj University Madurai in 2002 and 2004, respectively. He completed his school education in Thiruthangal, his native place. He was granted National Board for Higher Mathematics (NBHM) fellowship for both MSc and PhD. Further, he secured CSIR Junior and Senior Research Fellowship for his doctoral studies. He was a proud alumnus of the Mathematics Training and Talent Search (MTTS) programme held in 2002. Since 2013, he has contributed to MTTS as a resident faculty for various programmes organized across India. His research work involves working on problems that arise from Mathematicsl Optimization, Game theory and related areas. His other interests include open-source software packages, especially MOODLE, KOHA and SageMath. He has installed and customized MOODLE for CUTN (https://courses.cutn.ac.in) and MTTS Classrooms (https://classroom.mtts.org.in). Further, he has installed and coustomized KOHA for Chozha Central Library of CUTN (https://library.cutn.ac.in).

Research Highlights :

Dr A Chandrashekaran’s interests in Mathematical research involve Mathematical Optimization, Game Theory and Operations Research. His contributions are related to a class of Optimization problems called cone linear complementarity problems. He has published 15 research articles. His recent contributions are about the structure of proper cones in the theory of linear complementarity problems. 

In particular, he contributes by formulating OR problems from the industry as Mixed Integer Programming (MIP) problems and implementing different algorithms using open-source solvers. He is an honorary member of the advisory board of Cloud Supply Chain Solutions (cscs.io), a startup based in the USA and India.
