I have over 20 years' experience developing foods for and conducting dietary intervention trials.

My expertise resides both in the clinical and laboratory space. My key roles are to provide advice on design and implementation of dietary intervention trials/sensory evaluation studies with expertise in using a crops to clinic approach.

My training as a registered nurse, food scientist and a dental fellow has provided me a broad background and a unique expertise in conducting dietary intervention trials from a perspective of a clinician and scientist.

My research takes a crops to the clinic approach by translating food and crop innovations into dietary intervention trials.

I have over 20 years of experience in using various food processing strategies to improve the bioavailability of dietary food components as well as optimise food structures to enhance exposure of food bioactive components to localized and systemic targets.

At the Quadram Institute, I am a part of the QIB human studies team which is a translational research team dedicated to facilitating the delivery and management of human studies and human samples.

Specifically, I am focused on the delivery of dietary intervention studies both in humans and rodent models. Of my 48 publications, 33 involve human samples and of those 16 were dietary intervention trials involving food ingredients from crop innovations and/or development of novel food products.

Currently, I am the principal investigator on five dietary intervention trials. My group and the human studies team as a whole thrives on facilitating collaborative integration between bench scientists, crop scientists and clinicians both locally and internationally.
