  • 2021 – present: University Teaching Associate, University of Sheffield
  • 2014 – 2021: Postdoctoral Researcher, University of Oxford
  • 2011 – 2013: Postdoctoral Researcher, University of Leeds
  • 2007 – 2010: Postdoctoral Researcher, University of York
  • 2006 – 2007: Postdoctoral Researcher, University of Dundee
  • 2002 – 2006: Research Assistant, University of Dundee

I started my academic career when I joined the University of Abertay to study a BSc (Hons) in Biotechnology.

I then undertook a part-time PhD in Biochemistry and specialised in Structural Biology while I worked as a research assistant at the Welcome Trust in Dundee.

After obtaining my PhD, I worked as a postdoctoral research assistant in a hybrid industrial/academic setting at the University of York, where I solved many protein structures for Novozymes, the world’s largest industrial enzyme manufacturer.

I then moved on to purely academic studies of viral RNA-binding proteins at the University of Leeds, and enzymes involved in ADP-ribosylation, an important post-translational modification of proteins, at the University of Oxford.

I currently work at the University of Sheffield, where I teach molecular biology as a University Teaching Associate and I also branch out from studying nucleic acid-binding proteins, which have been the main focus of my research since my PhD, to also study plastic-degrading enzymes, which marks a return to where my science career first started: research in biotechnology.

Research interests

I specialise in structural studies of nucleic-acid binding proteins. My research has spanned viral RNA-binding proteins, bacterial DNA-binding toxin-antitoxin systems and archaeal DNA-repair enzymes involved in homologous recombination.

I recently started working on plastic degrading enzymes with of view of using a biotechnological approach to tackle one of the world’s greatest environmental problems: plastic pollution.
