Research Interests:

DEVELOPMENT OF NEW, MORE EFFICIENT, METHODS FOR MODELLING ELECTRONIC STRUTURE - Dr. Hollett's research involves the development of new, more efficient, methods for modelling electronic structure. Computational chemistry methods are plagued by the electron correlation problem. Accurate calculations require models that correlate the motion of electrons, however conventional models are generally too expensive, computationally, for large systems. An alternative is Natural Orbital Functional Theory (NOFT), which provides a framework for an economical and accurate treatment of electron correlation. A solution to the correlation problem lies with the development of an accurate natural orbital correlation funcitonal.

He is also interested in the application of existing computational chemistry methodologies to complex chemical problems, particularly, computational virology. The development of treatments for devastating diseases such as AIDS and hepatitis C is deeply rooted in understanding the complex interactions between viruses and the immune system. Much can be learned about these interactions by studying viruses such as HIV and HCV and cells of the immune system at the molecular level. The proteins involved in virus replication, T-cell recognition, and drug interactions can all be modeledcomputationally to shed light on this important biological problem.
