ΟΜΙΛΙΑ: Machine learning opportunities for a new generation of microwave-based medical devices

Printer-friendly versionSend by email

Abstract

This talk will present our progress towards two medical devices which we are currently developing using electromagnetic (EM) waves at microwave frequencies. The first device is a non-invasive sensor for monitoring glucose changes for diabetes patients, and the second is a portable scanner for stroke detection and monitoring. Both devices require processing information from signals which depend strongly on the complex interaction of EM waves with the human body as well as environmental factors such as temperature and instrument noise.
The talk will primarily present what we have accomplished so far with our hardware using traditional signal processing techniques for these problems. We will then discuss the motivation and possibilities for using machine learning methods to improve the accuracy of these devices and solve these huge healthcare challenges.

Speaker Bio

Dr Panagiotis Kosmas is currently a Reader at the Faculty of Natural and Mathematical Sciences, King’s College London, United Kingdom. He received the Diploma in Electrical and Computer Engineering from the National Technical University of Athens, Greece, in 1999, and the M.S. and Ph.D. degrees in Electrical Engineering from Northeastern University, Boston, MA, USA in 2002 and 2005, respectively. He has also held research positions at the Center for Subsurface Sensing and Imaging Systems, Boston, USA, the University of Loughborough, UK, and the Computational Electromagnetics Group, University of Wisconsin-Madison, USA. At King’s, he is currently principal investigator and project manager in research projects of total value around £3M, which are funded by Innovate UK, European Union’s H2020 Programme, and UK’s Engineering and Physical Sciences Research Council (EPSRC).
Panos co-founded MediWise Ltd UK in 2011, a bioengineering company which develops new commercial applications of radio waves in medical sensing and imaging. Mediwise was acquired by Canadian company Metamaterial Technologies Inc. in 2018, and Panos currently serves as a Vice President in Biomedical Engineering for MTI. In this role, Panos oversees MTI’s R&D in medical applications, including system simulations, antenna design, and the development of algorithms which can translate data from sensors and devices to meaningful diagnostic information.
His academic expertise extends to microwave engineering, signal processing and physics-based detection methods, and inverse problems theory and techniques. He has contributed two book chapters and over 90 journal and conference publications, and he has organised and delivered various short courses, special sessions, and workshops in these areas.
