About

Overview

Dr Karthik Budidha first came to City, University of London in 2006 to pursue his undergraduate degree (BEng) in Biomedical Engineering. Following his undergraduate degree, he acquired an MSc in biomedical engineering from Imperial College London in 2010. He then worked as a Biomedical Engineer in Hillingdon hospital for a year before returning to the Research Centre for Biomedical Engineering (RCBE), at City, University of London in 2011 to pursue his PhD. During his PhD he developed a novel In-ear oximeter to monitor arterial oxygen saturation and heart rate in patients with compromised peripheral perfusion.

Dr Budidha's primary interests lie in the design of novel wearable non-invasive sensors, and development of bio-electronic instrumentation to continuously monitor physiological and behavioural variables. Being named the primary researcher in the Wellcome Trust’s Pathfinder Award, he is currently working towards the development of a novel intra-luminal sensor for monitoring intestinal viability in colorectal cancer surgery.
