Greg read Natural Sciences at Cambridge before moving to Stanford for his PhD in neuroscience. His thesis research with Liqun Luo introduced the Drosophila olfactory system as a model for studying the development of wiring specificity in the brain. Since 2008 he is an MRC Investigator at the MRC Laboratory of Molecular Biology (where the first connectome of C elegans was obtained by White, Brenner and colleagues).

Greg’s group studies the genetic and circuit basis of behaviour focussing on sexually dimorphic circuits, olfaction and the interaction between learned and innate circuits. They are also heavily involved in Drosophila connectomics, including developing computational and experimental tools for analysis and exploitation of connectomes. Greg has a secondary appointment at the University of Cambridge, where he directs the Drosophila Connectomics Group, a collaboration with HHMI Janelia and the University of Oxford.
