Professor Anastasia Callaghan
Biography
I completed a BSc(Hons) in Biology with Chemistry at the University of Southampton before going on to complete a PhD with Prof Sir Howard Dalton FRS at the University of Warwick. This work focused on the biochemical and structural characterisation of bacterial protein complexes.
I then moved to the University of Cambridge to take up a Wellcome Trust postdoctoral position with Prof Ben Luisi where I worked on the structural and functional characterisation of proteins involved in RNA processing and degradation. During my time at Cambridge I was elected to Senior Membership of Wolfson College and taught biochemistry to medical and veterinary students at Queen’s College.
I subsequently joined Pfizer Global Research & Development as a Principal Scientist (Biophysics) within the Discovery Department’s Structural Biology Group. Contributing to multiple therapeutic areas, I led a focused team in conducting fundamental research in early stage drug discovery. This work gave me an invaluable insight into the applicability of academic research to pharmaceutical development.
I subsequently joined the 91¸£ÀûÍø, taking up a tenured Senior Fellowship before being promoted to Principal Fellow and Reader in Biochemistry & Molecular Biophysics. Although I hold a research-focused role, I actively support the teaching within the Department as well as holding a number of additional Departmental, Faculty, University and external responsibilities.

Research interests
I have an active research group focusing on the study of RNA biology, with interests in post-transcriptional gene regulation and developing tools for investigating RNA-based molecular interactions. Specific research interests include:
- 91¸£ÀûÍøing the interplay of non-coding RNAs, an RNA chaperone protein and ribonucleases in the control of gene expression; a novel mechanism linked to pathogenic bacterial virulence.
- Exploring a communicative link between the enzymatic machinery of RNA degradation and a key metabolite of central metabolism.
- Identifying chemical inhibitors of antibacterial targets and understanding their mechanism of action.
- Developing novel technologies for the study of RNA-interactions.
