Earlier in his career, Tim was a postdoctoral fellow at Genentech, where his studies on growth hormone receptor defined the now-established “hot spot” paradigm for how proteins interact. Tim received his Ph.D. in Biology from Cambridge University for research conducted under Dr. Greg Winter, FRS at the MRC Laboratory of Molecular Biology into antibody engineering and the development of antibody phage display technology, subsequently commercialized by Cambridge Antibody Technology. He received his B.A. degree in Biochemistry from Oxford University.
