We are dedicated to improving patient outcomes through innovation at the point of care. Diagnostic and therapeutic Medical Wearables, mobile Health applications for telemedicine, and optimized monitoring and objective informed decision-making software can revolutionize patient care and save lives.
Using our translational expertise, we marry biomedical engineering, computer science, and digital modelling with the aim of empowering clinicians to make better-informed decisions remotely and also at the bedside.
Our extensive team includes clinicians, neonatologists, physicists, neuroscientists, engineers, computer and data scientists, and animal technicians.

Medical Wearable Technologies (Wearables)
Wearables in healthcare is a category of electronic devices that can be worn, printed on skin or embedded in smart clothing to collect the patients' health information for e-diagnostics and to modulate organs systems as therapeutics.
Our theme researchers in Dunedin Campus are running numerous novel wearable projects, including (but not limited to) wearable olfactory nerve stimulator, wearable gastric neuromodulator, wearables for Parkinson Disease, Stroke-derived aspiration alleviation technologies funded by HRC and Medtech Core NZ in collaboration with national and international collaborators. Our theme also collaborates with the Biomaterials theme for embedded systems in smart suits. With the Internet of Things(IoT), such wearable technologies open horizons for timely intelligent medical analytics and remote management for diagnostic and therapeutic applications.
Mobile Health (mHealth)
mHealth is defined as the "use of mobile and wireless technologies to support the achievement of health objectives." by the World Health Organisation who indicated that “mHealth has the potential to transform the face of health service delivery across the globe.”
mHealth comprises a wide range of remote technologies, including mobile phone or tablet apps to electronic displays embedded into robotics and webcams assisted tools, miniaturized systems, and (but not limited to) the Virtual Reality and Digital Humans. The rapid adoption of such devices running medical applications enabled digital health for telemedicine with the Internet of things (IoT).
In the University of Otago, Dunedin Campus, we are running novel mHealth projects on diagnostic, and monitorization for Concussion, Posttraumatic Stress Disorder, Parkinson's Disease motor symptoms and Cardiovascular Diseases in collaboration with national and international research centres.
The Precision Health in Surgical and Intensive Care (PHySIC) group combines active clinical research, novel clinical databases, and machine learning to determine patient status and needs in critical care.
PHySIC is an open-source, anonymous archive database holding continuous wave-form data alongside the usual clinical information sourced from ICU's and intraoperative spaces across New Zealand's District Health Boards.
Through relationships with Wellington Regional Hospital, Capital Coast DHB, and clinical collaborators, our team is actively working towards creating a novel, New Zealand-specific medical database based on MIT's MIMIC (Multi-parameter Intelligent Monitoring in Intensive Care).
Data scientists and machine learning experts at the University of Otago, Wellington, and Victoria University Wellington are using the PHySIC database to create predictive models for sepsis, and cardiac surgery risk, the potential for innovating treatment with predictive models, extends to every corner of New Zealand critical care.
Translational and clinical researchers at the University of Otago Wellington campus have partnered with physicists and engineers at Victoria University Wellington with the aim to innovate bedside brain-health detection.
Through this collaboration, they hope to validate brain diagnoses and monitoring in an accessible paradigm. Making these capabilities more available will empower more clinicians in their decision making and lead to better care of critical neurological disorders.
