Timothy Constandinou is Professor of Bioelectronics at Imperial College London and also Deputy Director of the Centre for Bio-inspired Technology. Dr Constandinou received BEng and PhD degrees in Electronic Engineering from Imperial College London in 2001 and 2005, respectively. 

He leads the Next Generation Neural Interfaces (NGNI) Lab at Imperial. His group creates innovative neurotechnologies to enable communication between the nervous system and electronic devices -- for research tools and medical devices. 

He additionally is a Group Leader for "Bioelectronic Systems for Intervention in Dementia" within the UK Dementia Research InstituteCare Research & Technology Centre.

Within the IEEE he serves on several committees/panels, etc, regularly contributing to conference organization, technical activities and governance. He currently serves on the IEEE Circuits & Systems Society (CASS) Board of Governors for the term 2017-19, IEEE BRAIN Initiative Steering Committee, IEEE CASS Sensory Systems and IEEE CASS Biomedical Circuits & Systems Technical Committees and is the Deputy Editor-in-Chief of IEEE Trans. Biomedical Circuits & Systems (TBioCAS) for the 2020-21 term. He co-chairs the steering group of the Royal Society iHuman perspective on Neural Interfaces and the Ecosystem.
