The Department of Physics is delighted to welcome Professor George Malliaras (University of Cambridge) as a Colloquium Speaker for the academic year 2025/26. Please join us to listen to Professor Malliaras's seminar.

A reception will be held directly after the seminar in 8 West 3.15, where tea and coffee will be provided.

The seminar is open to anyone from the university, students are encouraged to attend.

Title

Materials and Devices for Bioelectronic Medicine

Abstract

Bioelectronic medicine provides a new means of addressing disease via the electrical stimulation of tissues: Deep brain stimulation, for example, has shown exceptional promise in the treatment of neurological and neuropsychiatric disorders, while stimulation of peripheral nerves is being explored to treat autoimmune disorders. To bring these technologies to patients at scale, however, significant challenges remain to be addressed. Key among these is our ability to establish stable and efficient interfaces between electronics and the human body. I will show how this can be achieved using materials with mixed ionic-electronic conductivity. I will discuss devices engineered from these materials to communicate with the body and evolve with it.
