Some of the bold initiatives include moving to a new building in 2005, augmentation of computing facilities and statistical software for the Lab and ICT enabled smart classrooms in the Department.
  7. Convener, CCSS Academic Committee: Coordinator of Choice-Based Credit Semester System (CCSS), Post-graduate Programmes, University of Calicut from 22- 10.2009 to 13-12-2012 (3 years).
    With a change over to a system of education introducing the Choice-Based Credit Semester system from the Academic year 2008-09 onwards for all Regular PG Programmes of University Teaching Departments/Schools, that offered sufficient scope to put the entire potential of the University Departments to action, we were able to streamline the functioning of the system by effective co-ordination of activities of the participating departments and examination wings.
