Emulsifier technology to enhance emulsion stability in milk coffee beverages.

Supervised by  Dr Graham Eyres and Patrick Silcock


Marcus comes from Kuala Lumpur, the capital of Malaysia. He obtained both his BSc in Biotechnology and MSc in Food Technology from Universiti Putra Malaysia. His master research thesis was “Detection and determination of furfural in crude palm oil”. After completing his Master degree, he worked in the R&D department of a major edible oils & fats, oleochemicals and food ingredients company.

He is currently pursuing a PhD degree in Food Science at University of Otago. He has chosen Otago because of the supportive and world class study environment that it offers. He is also keen to live and explore the beautiful South Island of New Zealand.

In the future, he would like to contribute back to society by sharing his knowledge through teaching, while pursuing his passion in research and development. His research interests lie in the area of fats & oils and oleochemistry.
