I am an entomology PhD student being co-supervised by Greg Sword. I am an ecologist by trade, with an ever increasing interest in insects. I’ve serendipitously worked with insects in many research projects and have found them to be extremely useful for many types of questions. My interests broadly lie in the field of nutritional ecology. I did my Master’s research at St. Cloud State, in MN, where I looked at the influence of dissolved nitrogen and phosphorus ratios on mayfly (Baetis) growth. Most of my research has related to ecological stoichiometry in aquatic systems; however, for my doctoral work I would like to focus on the relationship between nutrition and insect life history in terrestrial systems. More specifically, I am interested in how macronutrient and sterol availability affect longevity and susceptibility to stress in hemipterans (sucking insects). I am also fascinated by the “non-nutritional” aspects of food, and how resource composition can function as an indicator of environmental conditions, often inducing physiological changes in the consumer that are independent of nutrient limitation.
