Profile Summary

I specialise in computational approaches to uncover insights from large mobile health datasets for cardiovascular risk assessment. I am also interested in survival models, PKPD modelling, language models (including data mining in EHR and genAI), and web app development for other researchers to use. I have extensive experience in industry implementing ML approaches and designing ML-centric industry-scale production software architectures, including MLOps & CICD. In the academic domain, I share my time between Imperial College London and Stanford research projects. In the industrial domain, I help industrial startups like ValueBase and Aktana —and charities such as Cancer Research UK (CRUK)—extract greater value from advanced data analyses. The rest of my time is dedicated to teaching companies how to design effective data ecosystems within Google Cloud on behalf of Google.
