    17. Research projects and research papers awarded to the faculty increased. Almost 20 research projects are obtained for the institute as on today.

    18. Many infrastructure works were initiated and some of the ongoing PWD works were completed during my period. Details are as follows:

MCA block completed

Electrical Engineering Block completed

Electrical PG Software lab completed

Dhwani open air theatre completed

CETAA hall renovated

Biogas plants and LED lighting for the campus completed

AS obtained and works started for i) New PG Electrical Block ii) Extension of Electronics Block iii) Extension of Civil Engg. Block iv) New canteen Building v) New Block for Ladies Hostel vi) Rennovation of CGPU Hall vii) Rennovation of Existing Canteen

MBA Block and Diamond Jubilee Building nearing completion

Parking space,golden walkway and landscaping with donations from Alumni have been completed

Wells are being dug for tapping the water resources of the campus


Now as Director of Technical Education, she is pushing up the following ventures.

  • E-Governance to its full capability in the Directorate

  • Establishment of Technological University ( on the anvil)

  • Establishment of TREST (Trivandrum Science and Technology Park) in the CET campus( Started)

  • Upgradation of all Polytechnics with Central Assistance (71 Crores received)

  • E-Governance extended to all institutions

  • TEQIP Phase II in six Govt. Engg. Colleges
