Alex is interested in the effects of early-life or maternal environment on the life histories of individuals within a species. She is will be researching this by comparing and contrasting different hypotheses, such as the Silver Spoon Hypothesis and Predictive Adaptive Response Hypothesis, within a long-term study population of Yellow-bellied Marmots in Colorado, U.S.

During her PhD, Alex was co-supervised by Pierre Bize and Julien Martin.
