Jim Ajioka
Department of Pathology

Jim's lab works on development of synthetic circuits and protozoan biology. He leads an EPSRC Global Challenges Research Fund programme to build and employ low cost viral diagnostics, using Synthetic Biology techniques. Jim’s lab also takes on foundational work such as generalised codon optimisation, robust switches and counters and big DNA manipulation, as well as maintain a long interest in protozoan biology. Jim is co-Chair of the University of Cambridge Synthetic Biology Strategic Research Initiative, and co-founder of Colorifix, a startup that is developing sustainable textile dyeing processes, based on synthetic biology.
