Synthetic biology is a new, intriguing technology that could have a huge impact on humans and our environment. Adam Rutherford chairs a panel of experts, including Louise Horsfall, Paul Freemont, Susan Molyneux-Hodgson and Robert Edwards. This event was organised by the Biochemical Society and Royal Society of Biology as part of Biology Week 2015: http://www.rsb.org.uk/get-involved/biologyweek.

His interests are focussed on the biotransformation of synthetic compounds and natural products in plants and the manipulation of these pathways for applications in crop protection and biorefining using technologies including synthetic biology. Paul Freemont is Co-director of Centre for Synthetic Biology and Innovation at Imperial College London. The Centre aims to develop foundational technologies to enable synthetic biology research in application areas like biosensors, biosynthesis, bioprocessing and metabolic and genome engineering and enable the translation of new synthetic biology technologies into industry. Louise Horsfall is a Lecturer in Biotechnology at the University of Edinburgh. She is interested in multidisciplinary challenges involving Biotechnology, Synthetic Biology, Novel Enzymes and Protein Engineering. She is currently the elected co-chair of the Bioengineering and Bioprocessing Section of the European Federation of Biotechnology and a member of the EPSRC's Early Career Forum in Manufacturing Research. Susan Molyneux-Hodgson is Director of Research, Department of Sociological Studies, University of Sheffield. Susan co-founded and is currently Director of SATIS (Science and Technology in Society) research group in Sheffield. Her research is focused on three substantive areas: the sociology of scientific communities
