Overview
Background
Michael is passionate about plant-based foods, with a particular focus on their nutritional composition, quality, bioactivity, digestibility, and potential for promoting healthy diets. He has served as a Chief Investigator on several flagship initiatives, including the ARC Industrial Transformation Training Centre for Uniquely Australian Foods, the CRC for Developing Northern Australia, and the HIA-funded Naturally Nutritious project. His research emphasizes the importance of understanding both in vitro bioaccessibility—how compounds are released from the food matrix and become available for intestinal absorption—and the more complex in vivo bioavailability and metabolism, including microbial degradation in the gut. These processes are critical for predicting the bioactivity and potential health benefits of dietary phytochemicals in humans.

Phytochemicals and Health
My primary research interests focus on phytochemicals—specifically polyphenols (both bound and free), carotenoids, and betalains—as well as vitamins. I investigate their analysis, binding characteristics within the plant (food) matrix, and structural modifications or degradation during processing and digestion. This includes studying their bioaccessibility, bioavailability, and metabolism, essentially tracing the journey “from raw produce to absorbed and metabolised bioactive compounds.”
