Experts in AI for Fairness in Healthcare


Dr Rav Seeruthun and Professor Ian Colwill met in 2013 whilst studying at Cambridge University on the Executive MBA programme. The concept for health-equity.ai came from discussion of their shared interest of using the power of AI to uncover unfairness in access to healthcare and innovative medicines.

Before founding HE.AI, Rav was based in San Francisco and served as Vice-President of Medical Affairs at Genentech. Previous to this he was UK Country Medical Director for Roche.

During his time at Genentech Rav’s team was actively finding solutions to challenge health inequalities in the US. Whilst there he was shocked to discover that life expectancy can differ by up to 20 years depending on your ZIP code.


Ian is the founder of Catalyst Corporation, a technology consultancy providing research and development services to industry and government, including the novel application of Artificial Intelligence and Machine Learning.

Using the same AI techniques, Ian and Rav discovered that in the UK, there are over 50% more cases and 40% more deaths from certain types of cancer depending on your postcode.

The company was founded in April 2023, and signed their first customer, a top 5 Pharmaceutical Company, in July 2023.
