Dr Matthew Knox PhD, MSc

Research Technician

Doctoral Co-Supervisor
School of Veterinary Science

Matt Knox is an ecologist and molecular biologist with 8 years’ experience working internationally and at Massey University. After completing a PhD on the diversity of deep-sea crustaceans at University of Waikato, Matt worked for 3 years as a postdoctoral researcher at Colorado State University studying the effects of climate change on the fauna of the Antarctic Dry Valleys. Since returning home to New Zealand and his current role at Massey University, Matt’s research has focussed on cross species transmission (spillover) of infectious diseases, particularly protozoa (Cryptosporidium and Giardia) and viruses in New Zealand and abroad.

Teaching and Supervision

Graduate Supervision Statement

My skills lie in the area of molecular biology, particularly in detection of protozoan (Cryptosporodium and Giardia) biology, detection of pathogens from environmental samples, disease surveillance and phylogenetic analyses. 

Dr Matthew Knox is available for Masters and Doctorial supervision.
