Torrington Place


My inaugural lecture will be a collection of short stories from my journey to becoming a Professor of Biomedical Engineering at University College London. I will start by describing how I was introduced to the use of light and photons to look inside the body, followed by my PhD and postdoc years, running between the lab and the hospital; and from there how I lead a successful team and research programme of work in developing the next generation of brain imaging tools. Integrated within these stories are my teaching and outreach activities. At the end I will introduce the new approaches that my team are developing to transform patient metabolic imaging.

About Professor Ilias Tachtsidis

Profile picture
Prof Tachtsidis is an engineer working at the interface of technologies development and clinical application. His research focuses on the development of optical technologies to monitor and image the brain. Prof Tachtsidis is internationally recognised as a leader in the development of instruments that use light and have the capacity to image non-invasively how our brain cells use oxygen to produce energy. He has published extensively (more than 160 peer reviewed publications) and leads a successful programme of outreach activities via the Metabolight team that he leads, demonstrating how engineers and medical doctors work together to solve clinical problems and save patient lives.

Prof Tachtsidis also leads the MultiModal Spectroscopy (MMS) Research Group.
