Joel’s research interests are focused on the influence of plant-based dietary patterns and how these eating patterns influence health and exercise.

Specifically, his work has explored nutrient compositions in those following plant-based diets and how nutrient variations may modulate inflammatory, immune and antioxidant markers. Examining physiological responses and exercise performance outcomes of dietary patterns and supplements are also a focus of his research.

The impact of various dietary patterns on environmental sustainability and planetary health are other topics of interest and research.
