Biography
Professor Denison holds a Royal Academy of Engineering Chair in Emerging Technologies. At Oxford, he explores the fundamentals of physiologic closed-loop systems. Prior to Oxford, Tim was the Vice President of Research & Core Technology for the Restorative Therapies Group of Medtronic, where he helped oversee the design of next generation neural interface and algorithm technologies for the treatment of neurological disorders.
In 2012, he was awarded membership to the Bakken Society, Medtronic’s highest scientific honor, and in 2014 he was awarded the Wallin leadership award (only the second person in Medtronic history to receive both awards). In 2015, he was a Fellow of the American Institute of Medical and Biological Engineering.
Tim received an A.B. in Physics from The University of Chicago, and an M.S. and Ph.D. in Electrical Engineering from MIT. Recently, he completed his MBA as a Wallman Scholar at Booth, The University of Chicago.
He is a Royal Academy of Engineering Chair in Emerging Technologies for his work on brain engineering and was elected a Fellow of the Academy in 2024.

Research Interests
We are creating a new generation of physiology-inspired devices for restoring functionality to the nervous system. Our team works at the intersection of microelectronics, control systems, systems physiology, and health economics to advance bioelectronic therapies for neurological disorders. Our mission is to design and deploy pioneering instrumentation that enables first-in-human clinical neuroscience. These research instruments also serve as prototypes for therapy translation, enabling an assessment of the risks and economic factors to support successful approval by regulators and adoption by health services. Our work mostly falls within the “technology demonstration” (TRL5 to 6) of technology readiness levels in the NASA framework.
Our vision is to provide pragmatic therapies for intractable conditions such as generalized epilepsy, chronic pain, and disorders of consciousness, and make them available to the UK’s National Health Service and the world.
Our current research falls into three broad themes:
“Smart” Implants: improving the efficacy of implantable bioelectronic therapy systems in the central and peripheral nervous system through novel physiologic closed-loop control methods. We are currently supporting four active clinical studies*;
Non-invasive therapies: minimising therapy invasiveness through advancing transcranial magnetic stimulation, and probing and modulating brain activity with headsets that enable targeted memory reactivation; and
Resource-limited Neurotech: the development of hardware and algorithms for deployment in resource-limited healthcare ecosystems in partnership with universities across the globe. Researchers interested in joining our laboratory should take a “systems perspective” for tackling problems that are hard, but important. A clinician-partner is involved in every project we undertake.

Technology readiness level (TRL) set by NASA to determine the level of maturity of research and product developments (source: https://www.abaco.com/technology-readiness-level).
The research group is based at the Institute for Biomedical Engineering in the Department of Engineering Science. We maintain connections with many other research groups across Oxford, in the United Kingdom and internationally. Our current collaborations include the Nuffield Department of Surgical Sciences and the Surgical Intervention Trials Unit in Oxford, Imperial College London, The Surrey Sleep Research Centre, University College London – Great Ormond Street Hospital, King’s College London, and the Mayo Clinic in the USA. We are also founding members of the NIH-funded OpenMind consortium, where we support open-source quality management systems and deployment of first-in-human class 3 devices for the NIH BRAIN initiative. The group carries out this distinct programme of research within the MRC Brain Network Dynamics Unit at Oxford, where we support translational bioengineering. The lab’s activities are funded by organisations including The Royal Academy of Engineering, DARPA, MRC, NIH, Wellcome Trust, LifeArc, Moulton Trust, and industry collaborators.
