About

I'm a medical doctor (University of Cambridge) now at McKinsey & Company, where I work with QuantumBlack (AI by McKinsey) driving large-scale AI implementations. My focus is AI as a whole: where it's worth using, how it gets built, and what it takes for organisations to actually adopt it. Healthcare is where I've seen this matter most. The technology is rarely the hard part; the people, workflows, and trust are. I write about that here, with the occasional detour into health and fitness.

Background

  • McKinsey & Company, 2025 to present. Associate working with QuantumBlack (AI by McKinsey), promoted early. Recent work includes two AI implementations for leading pharmaceutical companies, sitting between client and technical teams so that delivery and adoption actually stick, alongside a commercial strategy engagement.
  • Medical doctor, NHS, 2023 to 2025. Worked across A&E, Diabetes & Endocrinology, General Surgery, Obstetrics & Gynaecology, and General Practice at Royal Bolton Hospital. Led multidisciplinary ward rounds, coordinated care for over 100 patients in the Emergency Department, and served as the most senior surgical doctor out of hours.
  • University of Cambridge, 2017 to 2023. MB BChir in Medicine with a Distinction (top decile), and First Class Honours in Neuroscience & Physiology. Awarded three scholarships and prizes for academic achievement, with research on food reward published in PNAS.
  • Exa Health, 2022. Interned at this Silicon Valley medical AI startup, where I built a computer vision glare detector (97% accuracy, transfer learning in Python and OpenCV) that lifted the app's success rates by 15 to 20%, and helped cut latency ahead of an acqui-hire.
  • Founder and President, Cambridge University AI in Medicine Society, 2021. Grew the society from zero to 400 members in under three months, running seminars on the practicalities, ethics and technology of AI in medicine, including hands-on sessions building models. Later coordinated a merger with the Cambridge University AI Society, opening access to a 3,000-strong community.
  • Runshaw College, 2015 to 2017. Five A* grades at A level, where most people take three. Ranked first in the year in every subject, with full marks in Maths and Further Maths and a perfect 9.0 in the BMAT science section, a score one or two people achieve each year.
  • Side projects. Chakra, an AI therapist for internet addiction; MedPal.ai, a wearable data insights app I co-founded; and other experiments in what AI can do for health. See the Projects page for things I've built and worked on.

Current focus

Helping large organisations get AI out of the pilot phase and into everyday work: the operating-model, workflow, and trust questions that decide whether an AI system is actually used.
