I am an associate professor in the Department of Mathematics, K.E.College, Mannanam, Kottayam, Kerala. I have completed 25 years of service. I graduated from University College, Thiruvananthapuram, Kerala University in 1986. I took my B.Ed. degree from Calicut university in 1989, MPhil degree from Kerala University in 1993, the area of study was: Non-Negative Matrices. I took my MCA from Indira Gandhi National Open University in 2002, completed my Ph.D. from Kerala University in 2010, the thesis was titled "Mathematical modelling of change in space of surface water in a tropical river system - rain to repository". I have also completed M.Tech IT. Presently I am doing my second Ph.D. in Computer Science on the topic entitled "Fuzzy Approaches and Methods in Software Engineering".

I am a Research guide in Bharathiar and Karpagam Universities. There are four research scholars under my guidance. My research interests are in the area of Graph theory, Fuzzy Modeling and Decision Making, Fuzzy Data Mining, Fuzzy Graph, Neural Networks and History of Mathematics.
