Biography
Research areaTheoretical and Mathematical Biology: My research interests lie at the interface of mathematics, life sciences and engineering where there are a wealth of problems for which novel and inventive solutions are sought. The application of applied mathematical methodologies for modelling, solution and simulation prove to be a powerful and stimulating component of such collaborative research activities.
With a particular interest in biomechanics and regenerative medicine, my collaborative projects cover such topics as modelling the lumbar spine, growth and function of the human epidermis, soft-tissue wound healing, tumour growth and fracture repair in bone.
Dynamical Systems: From a mathematical perspective, elements from many of these projects have led to models of chemotactically driven travelling waves and other issues of emergent behaviour wherein population or tissue level patterns evolve from small scale or cell level interactions.

Mathematical and Theoretical Biology I have an interest in the solution of ordinary differential equations as they relate to problems of dynamical systems in population and ecological contexts. Travelling waves solutions to coupled systems of partial differential equations provide a link form this interest in dynamical systems to problems of pattern formation and invasion in biological tissues.
Engineering Mathematics I have had a long-term involvement with the management and delivery of service teaching units in mathematics for various Bachelor of Engineering degrees and have been the recipient of an Award for Outstanding Contributions to Student Learning from the Carrick Institute for Learning and Teaching in Higher Education, 2006.
