Since 1990, the incidence of hypertension has increased globally, with up to one in three adults worldwide affected by it. Most of those people have no idea they have it. If people could diagnose and monitor hypertension at home, the World Health Organization estimates that up to 76 million lives could be saved with easy fixes, like stopping smoking or adjusting diet.
As the Magerstadt Professor of Cardiovascular Epidemiology, Khan studies the epidemiology of risk for heart failure. Using population-based cohorts and large electronic health record data analyses, she performs mechanistic studies that may enhance risk prediction and identify novel therapeutic agents for the prevention and treatment of cardiovascular disease. Khan and her team have developed a tool to predict risk and prevent cardiovascular disease such as heart failure, stroke, arrhythmia, coronary artery disease and many other conditions.
When people breathe, speak, sing or clear their throats, their bodies are in constant motion. Air flowing through the lungs, the oscillation of vocal folds in the throat and the rhythmic expansion of the chest all produce tiny vibrations that carry valuable information about physiology and health. However, constructing a device that can capture all of these physiological signals has remained a challenge.
AI plays an important role-but not by fixing fragmented data on its own. The work of organizing, connecting, and interpreting healthcare information still belongs to people and the systems they build. Where AI helps is after that foundation is in place: by bringing the right information forward at the right time, reducing the effort it takes to find what matters, and supporting better decisions in the moment of care.
Between March 2020 and March 2022, over 100 million telemedicine services were delivered to approximately 17 million Australians. The Australian government invested $409 million to make telehealth permanent, whilst the UK announced £600 million for digital health infrastructure in April 2025. Patient adoption is equally impressive: 60% find telemedicine more convenient than in-person appointments, 55% report higher satisfaction with teleconsultations, and 74% of millennials prefer virtual appointments for routine care. These aren't temporary shifts; they represent a fundamental transformation in healthcare delivery.
