Gandhi Engineering College (GEC) is situated in the City of Temples, Bhubaneswar. Established in the year 2006, with the approval of AICTE and affiliation from BPUT, the college is committed to impart quality technical education. Here, I was joined as a Senior Lecturer in IT dept. and involved in teaching the subjects like DS in C, C++ Programming (Theory and Sessional). I introduced Campus Connect Program (Industry-academia relationship) driven by Infosys within there campus with my colleagues. Above all, GEC is rich in knowledge and they have introduced a research oriented approach in their teaching methodology or classroom management.
