Scientist II – Treg Biology

Location: White City, London


At Quell we seek to deliver truly innovative, life-changing therapies for our patients. Our vision as a company is to build a major global biopharmaceutical company bringing transformational and valued therapies for a range of autoimmune and inflammatory diseases, as well as preventing rejection in organ transplantation, based on modular engineered Tregs.



Quell was founded in March 2019 in partnership with six prominent immunological experts from King’s College London, University College London, and Hannover Medical School, and is led by Iain McGill, a leading pharmaceutical executive with extensive relevant experience, having spent most of his 25 years in the industry in immunology, including the areas of solid organ and cell transplantation. The Company was founded with initial series A financing, led by Syncona Ltd who committed £59M with a further £2M contributed by UCL Technology Fund.
