I am a senior lecturer here at the Birkbeck Department of
Biological Sciences [formally Crystallography]. I started out as a
biochemist, then I took my PhD in protein
crystallography, followed by more structural molecular
biology here at Birkbeck, involving more
protein crystallography and homology modelling. I then
set-up a recombinant DNA facility to undertake protein
engineering using site-directed
mutagenesis and expression in micro-organisms. We have
targeted the enzyme
chymosin and the polypeptide hormone
insulin-like growth factor for modification. I teach mainly
on recombinant DNA technology and protein structure.
