Prof Ian Mackenzie
Mucosal biology.

Dr Steven Le Comber
My work covers a wide range of subjects within evolutionary biology, including studies of spatial patterns in biology, notably in epidemiology and invasive species biology, and mathematical and computer models of molecular evolution. Much of my current work focusses on geographic profiling, a statistical technique originally developed in criminology to prioritise large lists of suspects in cases of serial crime.

Dr Anwar Tappuni
My areas of expertise include diseases of the oral soft tissues, oral manifestations of HIV and oral ulcers. I lead a multidisciplinary research clinic for Sjogren's syndrome, supervising and supporting several postdoctoral and PhD projects. I have developed and published a clinical tool for assessing severity of oral ulcerative disease, which has been adopted for use in several units and employed in clinical trials.

Prof Lars Chittka
My research has established links between sensory physiology and learning psychology on the one hand, and evolutionary ecology on the other. Why do animals have the sensory systems they do? How do they use them in their natural foraging enviroment? How do cognitive-behavioural processes function in the economy of nature? Pollinator-plant interactions have been used as a model system to study these questions. I have been particularly interested in mutual evolutionary and ecological influences of insect colour vision and flower colour signals, and insect learning and flower advertising. In addition, I have studied bee navigation using large artificial landmarks, orientation of bees in complete darkness, as well as the question of how bees use spatial memory to navigate among several rewarded sites. Recently, I have also become interested in the evolution of cognitive capacities and communication, and the pollination biology of invasive plant species.

Dr Caroline Brennan
I am interested in the molecular mechanisms controlling behaviour. I am particularly interested in endophenotypes associated with psychological disease, including drug addiction and dementia. I use zebrafish as our model system combining behavioural analysis, imaging and cell biology techniques in wild type, mutant and transgenic lines to investigate the neural correlates of reward and learning behaviours.

Prof Maurice Elphick
The evolution and functions of molecules that mediate communication between cells in the brain (neurotransmitters) and how drugs like cannabis affect the brain.

Prof Mark Trimmer
My research looks at nitrogen and carbon cycling in aquatic systems, with a main emphasis in benthic sediments. Whilst my research was always either marine or estuarine based I have been investigating nitrogen cycling in lowland rivers, including the capacity of macrophytes to filter and process organic matter. I am also seeking to further understand the impact of anthropogenic activities in coastal seas by looking at the links between primary and secondary production in the western Irish Sea and the impacts of trawling in the North Sea.

Prof Michael Philpott
I am an expert on hair biology, which encompasses the role of growth factor and epithelial-mesenchymal signaling during hair follicle development, the hair growth cycle and the development of basal cell carcinoma (BCC).

Prof John Marshall
Tumour spread and metastasis; regulation of these by cell adhesion receptors and their associated molecules; molecular and cell biology.

Dr Shane Wilkinson
Parasite biochemistry/molecular biology; microbiology; drug discovery

Prof Lucinda Hall
My research interests centre on the evolution of bacterial pathogens, particularly in relation to antibiotic resistance. Other projects relate to the genetic mechanisms of mutation in Streptococcus pneumoniae, particularly in relation to the evolution of multiresistant strains with international spread. A developing area of research is in the microbiota of the gut and its interaction with the host in health and disease, in collaboration with groups within and outside the Centre.

Dr Gregory Michael
The function and characterisation of neural cells and response of these cells to injury; how neurons react to inputs such as temperature, mechanical force, pH and ATP levels in tissues, ultimately resulting in a perception of pain; which cells are involved and how each may respond to different stimuli or under different conditions (i.e. during inflammation); the relief of chronic pain; methods of stimulating neuronal recovery following injury.

Prof Ahmad Waseem
My research deals with the mechanisms that regulate differentiation and growth of keratinocytes in skin and oral epithelia. I am particularly interested in keratin proteins, which specifically characterize the epithelial nature of a tissue.
