Cancer Research UK, in collaboration with the Engineering and Physical Sciences Research Council, invites applications for its multidisciplinary project award. This supports collaborations between cancer researchers and scientists from engineering and physical science disciplines. The aim is to generate creative research ideas and explore their applicability in cancer research. Proposals across all engineering and physical science disciplines are welcomed. The research themes for this award include: •direct application of physics, engineering, chemical or mathematical concepts to address the underlying physical processes of cancer, including tumour initiation, growth and metastasis; •development of new transformational approaches or the translation of technologies for direct applications in, or a clear path to, a direct application in the prevention, diagnosis or treatment of cancer. Applications should ideally include a minimum of two PIs working in distinct scientific disciplines.
