My research area is in the use of computational solutions to ordinary and partial differential equations to answer questions in medicine and biology. Currently, my most active area of research involves developing a models for the healing of a tissue wound in order to understand the complex biochemical and cellular processes which are involved in the mechanics of wound healing. We are hopeful that mathematical models will shed light on which processes are most important in healing and explain why negative outcomes are observed. I also work on exploring airflow patterns in the human respiratory system using computational fluid dynamics. Many questions are unanswered regarding the importance of inter-individual differences in anatomy on flow and particle deposition, the impact of nasal surgery on olfaction, the optimization of drug delivery via the nose or lungs, and the impact of environmental air pollution on respiratory and systemic health.
