Marion Le Gall has always loved insects, and translated that interest into a career as a nutritional ecologist to study generalist herbivores. Her research seeks to understand how generalists solve the problem of balancing multiple and changing nutrient needs and how it affects their behavior and performance. She likes to use a physiological approach (the Geometric Framework) as a window into mechanisms underlying ecological patterns and processes. The overarching goal of her research is to use these insights to help establish sustainable management programs for herbivorous pests.
