Research

Research Interests

Involved in a wide range of research activities within the area of Parasitology. Research interest in host-pathogen interactions, epidemiology and integrated control of animal parasites. Keen interest in diagnostic parasitology, ranging from classical microscopy to serology and molecular techniques. Resent research projects focuses on anthelmintic resistance in ruminants and horses, Toxoplasma in food animals and Cryptosporidium in animals and the environment.
