Abstract: 

Recent progress in linear-scaling density functional theory (DFT) software allows electronic structure calculations of systems comprising many thousands of atoms to be performed on a routine basis, allowing access to typical length-scales in many biomolecules [1]. In this talk, I will give a few brief examples of some of the areas in the biological sciences where DFT can play a role - from the energetics of chemical reactions in enzymes and binding of small molecules by metalloproteins, to the parameterisation of model Hamiltonians to describe energy transfer in photosynthetic light-harvesting complexes.  In the second half of my talk, I will explain how we aim to use large-scale DFT simulations to parameterise classical force fields for the development of new anti-cancer therapeutics [2].
