Technology Development - p53 Lab

We are primarily interested in technology development with a view to generation of biologics (peptides and miniproteins) targeting dysfunctional p53 pathway components. In particular, we develop and employ a range of directed evolution methodologies for protein engineering and selection. These approaches are also being used to engineer/re-purpose enzymes for industrially relevant applications, with current focus on development of “greener” enzyme alternatives for pharmaceutical synthesis. A further area of interest is development of novel biosensing platforms, with emphasis on modular protein biosensors for facile drug screening and diagnostic applications.
