Cynthia Sun

Team Leader, Principal Research Scientist


Leading protein and enzyme biotechnology research

I'm currently the Team Leader and Principal Research Scientist in the Proteins and Enzymes team within the Biotechnologies group. I have deep experience and expertise in the field of biochemistry around biotransformation, protein extraction, glycoenzymes and bioassays.

Working alongside a team of exceptionally talented and smart individuals is a core motivation as we get challenged daily by customer requested projects needing research. My understanding of the complexities of proteins and enzymes enables me to lead the development of innovative biotechnological solutions.

As a member of the NZ Institute of Food Science and Technologies, I actively engage with fellow professionals in the field, staying updated with the latest trends and breakthroughs in the industry.

Throughout my career, I have been committed to research excellence to advance our understanding of proteins and enzymes and their industrial applications.
