Bio

Venkata Sunil Nag was born in Visakhapatnam, Andhra Pradesh, India in 1977. He completed his B. Tech. in Instrument Technology from University College of Engineering, Andhra University, Andhra Pradesh, in 2000 and M.Tech. in Electrical Engineering with specialization in Control and Instrumentation in 2001 from IIT Delhi. At present he is working towards his Ph. D. at Amrita Vishwa Vidyapeetham.

Before joining Amrita Vishwa Vidyapeetham in 2006 he worked in Bhabha Atomic Research Centre, Trombay, as a scientific officer from 2002 to 2005, after going through an orientation course in nuclear engineering for engineering post graduates. He secured 15th All India Rank in GATE-2000 in instrumentation discipline. During his Post graduate study at IIT Delhi he got institute scholarship. He is at present working as an Assistant professor in the department of ECE at Amrita School of Engineering, Amrita VishwaVidyapeetham Coimbatore, tamilnadu, India. His areas of interest are in instrumentation and control and specifically in the area of “model based fault diagnosis of electrical machines”. He is a member of IETE
