The hydrological cycle and the role of groundwater in maintaining human health and ecosystems underpin my research interests. In my research I aim to integrate methods from diverse backgrounds to deepen current understanding of hydrological processes, and how these influence the environment. These range from the role water plays in maintaining the health of wetland and aquatic ecosystems to the mobility of pathogenic micro organisms in the environment and how these may impact on human health (in both the developing and developed world). Findings from these activities can then be applied to inform legislators and practioners on approriate approaches to take in protecting the environment.  Following this approach I have published over 20 papaers in high impact peer-reviewed journals.

In my teaching I aim to demonstrate the importance of scientific principles for Engineers in making informed decisions and developing approriate solutions in a sustainable manner. My particular emphasis is on how geological conditions can influence both the built and natural environment. This is achieved in teaching courses in Engineering Geology (Level II) and Hydrogeology (Level IV).  At the same time I stress the importance of human and econmic elements in any Engineering project, and the ultimate responsibility of the Engineer to Society and the general public at large, through Engineering Ethics; this is an integral part of the Professional Studies module which I co-ordinate. On the other hand, I employ my field experience to demonstrate to Level I Civil Engineering students the inportance of a hands-on appreciation of activities and conditions that need to be considered in working on site through field trips (Engineering Geology II and Surveying field camp). Outside of the framework of formal classes I oversee research projects from Level III students through MSs thesis to PhD level supervision.

I have acted as an external consultant for clients providing services ranging from geophysical logging, wetland hydrological surveys and chairing public inquiries into activities with possible environmental repercussions.
