The first science department of Christ Nagar College, Maranalloor, the department of Physics with Computer Application, came into existence in the academic year 2015-2016. 29 seats were filled in the very first batch itself. The dual main course gives the students the opportunities to pursue their higher studies in either of the two subjects, ie either in Physics or Computer Science. The department is headed by Dr. Benny George, a doyen, who sees to the overall development of each and every student. The chief attraction of the department is its well equipped laboratory with top end instruments.
