About

AI & Digital Health Research Fellow at the National Heart & Lung Institute (NHLI), Imperial College London, and final-year medical student at Imperial College London. I graduated from Imperial College London with a Bachelor of Science in Cardiovascular Sciences, achieving First Class Honours, alongside my medical degree from a program ranked second globally by U.S. News & World Report. My academic and research interests sit at the intersection of clinical medicine, artificial intelligence, and health systems, with a particular focus on translating digital health technologies into routine clinical practice. Through involvement in large-scale, real-world research and implementation trials, I have gained first-hand experience of the practical, regulatory, and human factors that determine whether clinical AI delivers meaningful impact at scale. My work spans clinical trials, observational studies, and health systems research, with an emphasis on pragmatic study design, real-world outcomes, and clinician adoption. Alongside my academic work, I founded MedNex, a completely free, open-access research, mentorship, and career-development platform that now supports over 5,000 students and early-career clinicians globally. MedNex serves individuals from pre-medical students through to graduates, providing structured mentorship, access to high-quality research opportunities, and clear guidance on academic, clinical, and career progression in medicine. Built around the principles of access, clarity, and community, MedNex supports individuals at every stage of their medical journey and aims to reduce structural barriers to research participation and professional development. Building on this, I also founded MedVault, an international, free educational platform with over 1,000 participants. MedVault provides more than 700 high-yield practice questions mapped comprehensively to the United Kingdom Medical Licensing Assessment (UKMLA) content map, alongside structured webinars, all offered completely free of charge. Through both initiatives, my aim is to democratise access to research, mentorship, and high-quality medical education, particularly for individuals who may otherwise lack institutional or informal support networks. Overall, I am particularly interested in clinically grounded AI research, implementation science, and projects that bridge academia, healthcare delivery, and policy, with the goal of improving patient outcomes at scale, while also expanding mentorship and access to high-quality opportunities in medicine.
