## About

Rosetrees Trust was established in 1987 by Nat and Teresa Rosenbaum, with their son Richard Ross assuming leadership and building the Trust into one of the UK's most prolific private medical research funders. The Trust directs the overwhelming majority of its funding to translational medical research — the precarious stage where laboratory discoveries are developed into patient treatments. Its grant-making spans oncology, cardiovascular disease, neuroscience, and regenerative medicine, with a structural preference for early-career researchers and proof-of-concept studies that struggle to attract government or large-charity backing. Confirmed institutional co-funders include the British Heart Foundation and Leukaemia UK, with whom Rosetrees jointly runs the John Goldman Fellowships. The Trust also partners with Nesta on a Challenge Portfolio targeting healthy-life extension initiatives. Rosetrees has deployed over £60 million across more than 2,000 research projects since inception, supporting in excess of 400 PhD studentships. Richard Ross continues to lead the Trust as Chairman and CEO, while Jamaria Kong, a Managing Director at TowerBrook Capital Partners, serves as a Trustee — linking the Trust's governance to institutional private-equity disciplines. The Trust is a member of the Association of Medical Research Charities and adheres to its standards for independent peer review. In recent years, it has sharpened its focus on interdisciplinary research at the intersection of AI and medicine. What structurally distinguishes Rosetrees is its founder-led, family-governed decision-making paired with an institutional-quality peer-review process. Unlike large charitable foundations with bureaucratic grant cycles, the Trust can commit to high-risk projects in weeks. Its perpetual-life structure — no fundraising cycles, no donor constraints — allows it to back decade-long research arcs that venture capital and government grants structurally cannot underwrite. This makes it a genuine bridge funder in UK medical science, operating at a scale disproportionate to its relatively modest endowment.

## Questions

### How does Rosetrees Trust source its research projects?

Rosetrees operates an open application process through its website and maintains deep, long-standing relationships with research offices at UCL, Imperial College, King's College London, and the University of Cambridge. The Trust specifically solicits proposals for translational and interdisciplinary work that falls between basic science and clinical trials. Its membership in the AMRC requires it to use independent external peer review for all funding decisions, giving it de facto access to a wide network of UK scientific assessors.

### Does Rosetrees Trust co-fund with other charities or government bodies?

Yes, the Trust regularly co-funds with major UK medical charities. Known co-funders include the British Heart Foundation and Leukaemia UK, with whom it jointly administers the John Goldman Fellowships. It has also partnered with Nesta, the UK innovation foundation, on a Challenge Portfolio for healthy-life extension. These co-funding arrangements allow Rosetrees to participate in larger projects while maintaining its lean operational structure.
