Dr Mark Collett BVSc, MMedVet(Path), DipTertEd, MEd(CAI)

Senior Lecturer

Institute of Vet, Animal and Biomedical Sciences

I am a registered specialist veterinary pathologist with the VCNZ. I have been teaching veterinary pathology for more than 30 years. My main research interest is liver diseases and photosensitisation of farm animals. 

My main research interest is photosensitisation diseases of cattle, sheep, horses, and dogs, This includes facial eczema as well as brassica-associated liver disease (BALD) in cattle, rape scald in sheep, spring eczema in calves and adult cattle, and other photosensitivity diseases of unknown cause. I lead a team investigating the cause of the large swede-associated liver disease outbreak in dairy cows in 2014.
