Deontics was founded by clinicians and engineers who set out to understand how doctors make decisions, and to model a system based on it.
Originating from foundational AI technologies developed at Oxford University, and with a rich legacy of over 300 peer-reviewed clinical publications, our exceptional founding team have spent more than a decade advancing Deontics’ technologies into a robust and highly capable intelligent healthcare system.
Dr. Ioannis Chronakis
Founder, Chief Technology Officer and Board member
Dr. Ioannis Chronakis is the Chief Technology Officer and one of the Founders of Deontics as well as a member of the Board. He started his career as a medical doctor after graduating from the University of Patras medical school. Fascinated by the internet revolution of the 90s, he switched to a software engineering career.
Ioannis has experience in network and internet ecosystems, cloud style services, and has led internet companies’ technical teams. His interest in cutting edge technologies led to a career shift to robotics and aerospace where he worked in the development of physics simulation software (used to plan and test the delivery of payloads to the international space station), software to deal with network latency issues while remote controlling devices in orbit, and applying space telemetry technology to ground solutions.
In 2006, Ioannis combined his medical and engineering careers by joining Professor John Fox in the Advanced Computation Lab at Cancer Research UK, where he took over the development and evolution of the clinical decision support software platform. The platform has since developed and tested various clinical applications in National and European projects. He shared a common drive with Professor Fox, in moving the technology and science from research to application and making an impact. This led to spinning out Deontics, where Ioannis leads the technical team, providing a bridge between the clinical and technical aspects of the company.
Dr. David Glasspool
Founder and Head of Knowledge Engineering
David has a PhD in Computational Neuroscience from University College London and an MSc in Cognitive Science from the University of Manchester. He has worked in the computer industry and as an academic computer scientist and psychologist.
David led research groups at Cancer Research UK and Edinburgh University and worked for many years on clinical decision making and the effective communication of risk and uncertainty. He has extensive experience of applying theoretical work in computer science and artificial intelligence to practical clinical computing systems. He was a core member of the team at Cancer Research UK which developed the PROforma language for representing clinical decisions and processes and which spun out Deontics.
Dr. Vivek Patkar
Founder and Chief Medical Officer
Vivek is the Chief Medical Officer and one of the Founders of Deontics. He is a former breast consultant who trained as a surgical oncologist at TATA Memorial hospital – the largest tertiary cancer hospital and research centre in India – after graduating in medicine from the University of Bombay in 1995.
Vivek has a longstanding research interest in the application of AI based knowledge representation techniques for clinical decision-making. While working as a fellow in the AI in Medicine laboratory in Cancer Research UK between 2004-07, Vivek developed a number of clinical decision support applications for cancer as well as other indications, which were piloted and published in peer reviewed journals. Later as a part of collaboration between Oxford and Edinburgh Universities, Vivek led a team of researchers at UCL medical school (Royal Free Hospital) which worked on improving the quality of decisions made in cancer multi-disciplinary team meetings using clinical decision-support.
Vivek has worked in large research consortiums funded by European Commission research grants. Vivek and collaborators at Guys & Kings hospitals were successful in getting an NHSx and NIHR AI in Health and Care Award in 2020.
Vivek’s expertise includes:
– Surgical practice in oncology and breast surgery
– Extensive experience in working in the NHS
– Clinical informatics and EPR systems
– Clinical decision support
– Knowledge representation
– Evidence based medicine
– Shared decision-making and patient involvement
Professor John Fox
In August 2021, Professor John Fox – a great pioneer of biomedical informatics – passed away. John was one of the Founders of Deontics, and a core component of the Deontics platform is built around the PROforma system he devised. His hard work and dedication to making an impact in the world was pivotal in spinning out the company. He acted as the Chief Science Officer until 2020 and afterwards a part time consultant and board member.
In Memoriam. Safe, Sound and Profound: A Tribute to Prof. John Fox, PhD, FACMI, FIAHSI (1948–2021)
John Fox was a biomedical informatics pioneer. He was a scientist, leader, educator, serial entrepreneur and passionate advocate for the use of high quality clinical decision support systems (CDSS).
His greatest fame comes from his creation of the PROforma formal computer language for modelling clinical decisions and processes. Rooted in psychology and cognition, PROforma reflects the understanding of human decision making, follows rigorous software engineering practices and has clear and consistent semantics. John implemented and trialled over 15 CDSSs using PROforma, providing safe and sound decision-support to different healthcare organisations in different countries.
John Fox was an interdisciplinary researcher with theoretical interests in AI and computer science and an applied focus in medicine and medical software engineering. After training in experimental psychology at Durham and Cambridge Universities in the UK, and post-doctoral fellowships at Carnegie Mellon University (working with AI founders Herb Simon and Allen Newell) and Cornell in the USA, he joined the Medical Research Council in Sheffield UK, to establish a program of research in decision-making and clinical decision support. In 1981 he set up the Advanced Computation Lab at the Imperial Cancer Research Fund (now Cancer Research UK) where research focused on applications of knowledge based systems in oncology and primary care. However, the group was explicitly multidisciplinary and made contributions in basic computer science, safety critical systems, AI and medical informatics, and developed a number of technologies which have been commercialised.
In 2007 John moved to the department of Engineering Science at Oxford University to set up an interdisciplinary research collaboration with Edinburgh University and University College London, and a clinical informatics incubator at the Royal Free Hospital in London. The incubator ran a number of successful trials of AI technologies and spun out two companies to take the technologies into clinical use: OpenClinical CIC and Deontics Ltd.
In 1996 he and his team were awarded the 20th Anniversary Gold Medal of the European Federation of Medical Informatics for the development of PROforma, one of the first formal computer languages for modelling clinical decisions and processes.
