​Research projects

Took part as one of the scientist of prestigious Indo-Russian bilateral scientific joint project with financial support from Department of Science and Technology (DST) and Russian Science Foundation (DSF) for 3 years during the year 2016-2019. The Joint project is operated between CMS College Kottayam and V. A. Trapeznikov Institute of Control Sciences of Russian Academy of Sciences, Moscow, Russia. The title of the project was “New set of mathematical models, methods, algorithms and software programs of controllable stochastic systems for performance evaluation and design of the next-generation telecommunication networks”. 
A minor research project of UGC has been completed for an amount of Rs. 1.7 lakh under UGC 11th plan (MRP(S) 0291/12-13/KLMG003/UGC-SWRO dated 23-09-13).
