My journey
I was raised in South London, I went to school there with my two brothers. I won a prestigious Arkwright Scholarship for a career in Product Design, inevitably opting for Medical School at King's College London. Here, I met a series of mentors who set me off on a journey of academia and entrepreneurship. I established self-designed public health research as a medical student, which led to my first series of accolades (American Thoracic Society Abstract Scholarship Award, British Lung Foundation Research Grants, Royal Society of Medicine Young Respiratory Investigator Prize and RSM Young Epidemiologist Award, and others). I've been awarded 30+ national and international awards alongside a multitude of academic publications and book chapters. During these years I also built medical education courses, teaching students from 8 countries across Europe, India and the States, and helped establish research awards with the British Lung Foundation. My PhD focused on electrical stimulation to treat obstructive sleep apnoea, including the TESLA home-based trial published in The Lancet's eClinicalMedicine. My research on tobacco health warnings, e-cigarette advertising and sleep apnoea has since been cited in government policy by the US FDA, the UK Government and UK Parliament, the Parliament of Singapore, the Australian Government and the European Commission, and in clinical guidelines from the European Respiratory Society and the US Departments of Veterans Affairs and Defense. My current focus is two-fold: 1) building health tech in the largely untapped 'sleep' space to optimise patient health globally for a more focused, healthier society, and 2) laying the foundations for truly benevolent AI. I feel both are important societal missions. Welcome!

Growing up
School and University

I was born and raised in Tooting Broadway in South London, sharing a room with my two brothers.
