Role at Cawthron

Sam is an analytical chemist with 14 years' experience in internationally accredited laboratories, having held senior roles such as laboratory manager and technical consultant.

Sam’s unique combination of technical and analytical chemistry expertise has led him to develop and validate a number of methods on state-of-the-art instrumentation.

His research focuses on the chemical analysis of harmful algal blooms for biotoxins and the bioaccumulation of these toxins in marine species, as well as on the isolation and purification of natural products.

Sam’s current work within MBIE’s Safe New Zealand Seafood programme is aimed at enhancing the understanding of microalgal species abundance, distribution and toxicity in the South Pacific ocean, in particular the species associated with ciguatera fish poisoning.

This work, in conjunction with a scholarship from the New Zealand Food Safety Science and Research Centre, will form the basis of his PhD.
