Associate Professor Wee Sim Choo completed a Bachelor of Science in Food Studies (2000) majoring in Food Quality Management with a First Class Honours and Master of Science (2004) in the field of Food Chemistry and Biochemistry from the Universiti Putra Malaysia. She then joined the Malaysian Palm Oil Board as a research officer before moving to the University of Otago, New Zealand to complete a Ph.D. in Food Science in 2008. She joined the Faculty of Applied Sciences, UCSI University soon after and then the School of Science, Monash University Malaysia in 2009. In 2013, she obtained a Graduate Certificate in Higher Education from Monash University.

Associate Professor Wee Sim Choo has been awarded three PVC’s Awards for Excellence in Teaching (2010-2011) and one PVC Commendation for Excellence in Education - Innovations in Teaching (2020). She also received the PVC Commendation for Excellence in Research – Postgraduate Supervision in 2024, Most Popular Supervisor in Monash University Malaysia and Supervisor of the Year of the School of Science awards in 2022 from the Monash University Postgraduate Association (MUPA). She was an Outstanding Nominee for the Best Supervisor of the Year Award in 2018.

Her current research interests focus on functional foods, which are foods that potentially offer health benefits beyond basic nutrition. Her work focuses on the extraction and application of bioactive compounds from food sources, phytochemicals, probiotics and prebiotics. She is investigating and pioneering works on various bioactivities of natural-coloured pigments such as betalains and anthocyanins. She currently serves as an Associate Editor for Sustainable Food Processing (specialty section of Frontiers in Sustainable Food Systems), an editorial board member of International Journal of Food Science and Technology and an editorial advisory board member of ACS Food Science and Technology. She was on Stanford University's list of the World's Top 2% Scientists 2024.

Functional foods, phytochemicals and their bio-activities, natural colourants, probiotics and prebiotics.
