Electrical and Electronics Engineering
M. S. Ramaiah Institute of Technology (MSRIT) was started in 1962 by the late Dr. M.S.
Ramaiah, our Founder Chairman who was a renowned visionary, philanthropist, and a pioneer in
creating several landmark infrastructure projects in India. Noticing the shortage of talented
engineering professionals required to build a modern India, Dr. M.S. Ramaiah envisioned
MSRIT as an institute of excellence imparting quality and affordable education. Part of Gokula
Education Foundation, MSRIT has grown over the years with significant contributions from
various professionals in different capacities, ably led by Dr. M.S. Ramaiah himself, whose
personal commitment has seen the institution through its formative years. Today, MSRIT stands
tall as one of India’s finest names in Engineering Education and has produced around 35,000
engineering professionals who occupy responsible positions across the globe.
About the Department:
The department was started in the year 1962 along with the establishment of the college. It was
offering undergraduate program till 2003. In 2003 the Dept. was recognized as a Research Centre
by Visvesvaraya Technological University, Belgaum and started offering Ph.D. and M.Sc.
(Engg.) programs. In 2004 the Dept. started to offer PG program in Computer Applications in
Industrial Drives.
The department has 18 well-qualified faculty members. The entire faculty holds postgraduate
degree in either Power Systems / Power Electronics. Four of the faculty are doctorates. Dr.
Premila Manohar is Ph.D in HVDC transmission (from HVE, IISc., 1991), Dr. Sanjaya
Lakshiminarayan is doctorate in Power Electronics & Drives (from CEDT, IISc., 2007), Dr.
Pradipkumar Dixit is specialized in High Voltage Engineering (Ph. D from Visvesvaraya
Technological University, Belgaum, 2009) and Dr.T.V.Snehaprapha is Ph.D in Power
Electronics & Drives (from JNTU, Hyderabad, 2015). In addition, Dr. G. R. Nagabhushana,
with a long record of service (Retired Professor from HVE, IISc., Bangalore) is with the
department as Professor Emeritus.
