Keith Fraser

Sr. Lecturer, Biological Sciences

Dr. Fraser's research interests are broadly in the area of computational biology and how in silico models can be developed to advance our understanding of a range of biochemical mechanisms. These include protein folding, protein ligand interactions and drug toxicity.
