Peter Cullen is Professor of Biochemistry at the University of Bristol. He is distinguished for his ground-breaking discoveries on protein sorting and recycling in mammalian cells which plays a fundamental role in normal cell function.|His rigorous mechanistic dissection of the endosomal network has provided the framework to understand and interpret the underlying de-regulation of endosomal cargo sorting observed in a broad array of human diseases. These include cardiovascular disease and neurological disorders, most notably Alzheimer disease and Parkinson disease, as well as metabolic disorders such a type 2 diabetes. His work has opened up new therapeutic targets for the treatment of these diseases.|
