Dr. C. C. Reddy (डॉ. सी. सी. रेड्डी)

Associate Professor (सह - प्राध्यापक), Senior Member of IEEE
Department of Electrical Engineering (विद्युत इंजीनियरिंग डिपार्टमेंट)


After his ME & PhD from Indian Institute of Science (respectively in July 2005 and Jan 2008), Dr. Reddy has joined, J-Power Systems Corporation, Hitachi, Japan, a joint venture company of Hitachi Cables Ltd. and Sumitomo Electric Company and served as a Senior R&D Engineer in its Ultra High Voltage (UHV) research lab (one of the worlds few UHV Laboratories) for about four years. Added with good amount of pre-doctoral teaching experience in several Electrical subjects, he is in favour of deep industry-academic cooperation for the development of India. Dr. Reddy had in fact participated in academic-industry collaborative research in Japan with several universities of Japan (Toyohashi University; Waseda University; Tokyo City University; Numazu Institute of Technology, etc.). He had also participated in the deliberations of technical standards committee on Space Charge Measurements in dielectric materials. Dr. Reddy has published papers in reputed journals and conferences (IEEE/IET/IEEJ), in the fields of Nano-dielectrics, Power Cables (HVDC/AC), Power Transformers, Bushings; Mechanism of Breakdown, Space Charges and Conduction in dielectric materials. He had also co-authored a book with Prof. Ramu (retired) of IISc after his Doctoral Degree. He relocated to India after the massive earthquake of 2011, in Japan. Currently he is working as an Associate Professor in Electrical Department, IIT Ropar, since 2011. Apart from research he is interested in teaching and training the young generation to meet future needs of the country. Towards meeting this all round development objective, apart from publishing in reputed journals, like IEEE, he put emphasis also on teaching and developing laboratories. He is happy that he made two labs, one for research and the other for Undergraduate students within three years after joining IIT Ropar. He is currently guiding four Ph.D students; two of them already completed their comprehensive examination. One student has already defended Thesis. He got sponsored projects which are of highest budget in the department as well as in the institute at the time of their award nearing to about Rs. 1.5 crores. He has served as Faculty-in-charge of Guesthouse for two years and served several administrative jobs including Placement Adviser, RPEC representative (longest service) etc. He is crucial in preparing original annual report of the department and brochure for the department.

UG (HV) Lab:

High voltage lab is developed quickly by Dr. Reddy for supporting lab component of high voltage engineering (EEL 314, EEL 705) for undergraduate students.

It is aimed at training students opting for core power companies like ABB, Schneider etc.

It is located at Room No:136. Each year about 60 students are registering the course making the lab to run three times a week for lab work - one of the busiest labs of the department.

Among the new generation IITs this is believed to be the first high voltage lab in the area of Electrical Engineering. The lab is also supporting/being supported by sponsored projects.


The equipment is partly sponsored by the institute and the rest purchased from Dr. Reddy's projects.

Likes "Karma Yoga" of Geeta (click here). Likes the great philosopher "Krishna". Especially his words "Samatvam Yogamuchyate" (Yoga is same as being equanimous or neutral to all and in all situations). Practicing it while learning from errors on the way.


I believe that I am Straight forward, Righteous and Fearless.....some tend to interpret in their own way (:)
