Molecular Biosciences focuses on the molecular mechanisms underpinning biological function. The Division has a broad strength that spans biochemistry, structural and synthetic biology, cell biology, molecular genetics and developmental biology. The groups within Molecular Biosciences focus on a variety of biological systems including Drosophila, yeast, Arabidopsis, tobacco, Dictyostelium, and mammalian cells, and have a growing strength in the use of post-genomic and systems approaches to solve biological problems. Molecular Biosciences is an innovative, well funded and cohesive Division with excellent modern facilities for a broad range of techniques. It has close links with Chemistry in structural biology and with Physics in the development of advanced imaging technologies, and collaborates globally with academic and industrial partners. Research within Molecular Biosciences has a broad impact in areas including increasing our understanding of basic biological systems, improving diagnosis and therapy for human diseases and the development of novel commercialisable technologies.
