About

Chris Thomas - Research in 60 seconds videoProfessor Thomas joined the University of Birmingham in 1980 as a Lecturer in the Department of Genetics and has been Professor of Molecular Genetics since 1991. He is an internationally recognised authority on bacterial plasmid and mobile DNA and within the university has championed Biotechnology. He was also a founder of the successful Medici Programme that encourages development of Enterprise and Outreach.

Qualifications

MA Biochemistry (University of Oxford, 1974)

DPhil Microbiology (University of Oxford, 1977)

Biography

After undergraduate training at The Queen’s College in Oxford (1970-1974) and postgraduate study at Linacre College Oxford (1974-1977), Chris Thomas worked with Professor Donald Helinski in California funded by an MRC Travelling Fellowship (1977-1979). He then returned to a Lectureship in Genetics at the University of Birmingham in 1980. He was promoted to a personal Chair in 1991. He was first Director of the Biosciences Graduate Research School from 1999-2004 and was the first Director of the University Graduate School from 2005-2009. He was Editor in Chief for the journal Microbiology from 2000-2005. He was one of the founders of the International Society for Plasmid Biology in 2004 and was its first Secretary.

Teaching

Professor Thomas is Director of Graduate Research in the College of Life and Environmental Sciences. He supervises PhD students and Undergraduate/Masters projects and delivers postgraduate training. His prime area of expertise is bacterial genetics, cell biology and biotechnology. He currently teaches first year Genetics (Bio154) as well as contributing to third year courses Bio317 (Prokaryotic Genetics and Gene Regulation) and Bio303 (Applied and Environmental Microbiology).

Research

Research Theme within School of Biosciences: Molecular Microbiology

Microbial genetics and biochemistry, particularly in relation to plasmids, antibiotic resistance and antibiotic biosynthesis

Full research description

Professor Thomas’ research covers two areas:

Bacterial plasmids: replication, stability, gene spread, global regulation

Bacterial plasmids are important because of their role in spreading genes horizontally within bacterial populations and as tools for genetic manipulation. His group has carried out detailed investigations of the genes which control DNA replication, plasmid segregation and conjugative transfer between dividing cells, including how they are regulated with the view to help displace them in clinical and veterinary contexts but improve their properties as vectors. He is collaborating with a number of colleagues to understand plasmids as systems and as agents underpinning the emergence of new infectious diseases due to the spread in the environment.

Polyketide antibiotic biosynthesis

New antibiotics are required for use in medicine. We are working on two important and related pathways. First, we are studying biosynthesis of Mupirocin in Pseudomonas fluorescens with a view to generating new forms of this polyketide antibiotic that can be used against the superbug MRSA. This antibiotic has a number of unusual features that may be important for expanding the repertoire of building blocks for synthetic biology. Second, we are studying the biosynthesis of the related antibiotic Thiomarinol in marine bacteria in order to understand how the additional elements of this antibiotic are made and how they increase the potency of the antibiotic compared to mupirocin.

Other activities

Professor Thomas is Managing Director of Plasgene, a spinout company set up to commercialise tools for plasmid displacement.
