Dr. Karthi Balasubramanian currently serves as Assistant Professor in the Department of Electronics and Communications Engineering at Amrita School of Engineering, Coimbatore. He received the Bachelor of Technology degree from Netaji Subhas Institute of Technology (formerly known as Delhi Institute of Technology), New Delhi, India in 1999 and M.S degree from Simon Fraser university, Burnaby, Canada in 2002. He worked as a VLSI chip design engineer at Cogent Chipware Inc. and PMC-Sierra at Burnaby, Canadafor three years before joining as a faculty at Amrita Vishwa Vidyapeetham.

His areas of interest include VLSI for communication; non-linear dynamics and complex systems. Currently his research pursuits include‘VLSI design of reliability based soft decision decoders’ and ‘Exploring the use of non-linear dynamics and complexity analysis for identification of biomarkers for early detection of epileptic seizures usingheart rate variability (HRV) and EEGdata.

He has published papers in top tier peer reviewed journals and conferences and a book chapter. He also serves in the technical program committee of the flagship IEEE International Conference on Consumer Electronics (ICCE).
