Mark's areas of expertise include preventive veterinary medicine, epidemiology and control of infectious diseases of ruminant livestock, and veterinary public health, both in the UK and internationally, focussing particularly but not exclusively on vector-borne and parasitic disease.
He has conducted research in the field of international animal health, including zoonotic diseases, and held a number of large collaborative grant awards. His main research interests are diagnosis, epidemiology and control of diseases of farmed livestock of economic importance. Three major research themes have included control of neglected zoonotic diseases, integrated control of vector-borne diseases and trypanocidal drug resistance. Earlier research focused on the epidemiology and control of major vector-borne protozoan diseases of livestock, including tropical parasites such as trypanosomiasis and tick-borne diseases.
He is a Board Member of the Food Security and Land Research Alliance among the Universities of Bath, Bristol, Cardiff, Exeter and Rothamsted Research. A particularly important focus for the activity of the Alliance is the Rothamsted Research - North Wyke Farm Platform in Devon, a state of the art research facility for farm scale research on biophysical processes that influence agriculture and the environment, and a key node in the Global Farm Platform network.
