Founder, trustee and biotech CEO
Tim is a social entrepreneur passionate about delivering the next generation of therapeutics to rare disease patients in need. He is the Founder and Chief Executive of Healx and the Co-Founder and Chair of the Cambridge Rare Disease Network (CamRARE), a charity aiming to foster dialogue and awareness around rare diseases in Cambridge, UK.
Prior to Healx and CamRARE, Tim worked on University-Industry interactions in the area of Life Sciences for the UK Government Department for Business, Innovation and Skills (BIS).

Tim’s research interests are in the biochemical genetics of rare inborn errors of metabolism, latterly with special reference to lysosomal diseases: he has authored numerous original articles including reviews and research publications. Recently he has conducted therapeutic research in gene transfer as well as clinical trials leading to the global approval of two therapies for Gaucher disease, an ultra-rare disorder. An Internist and Metabolic Physician, he is an Editor and author of The Oxford Textbook of Medicine, of which the 6th Edition is in late-stage preparation.
