Her research is known for pioneering experimental approaches to study species geographic distributions.
Angert co-authored one of the most influential reviews of the ecological and evolutionary mechanisms that limit species geographic ranges.
[1] Her synthesis of climate-driven range shifts highlighted the difficulty in predicting which species will be able to track climate change.
Experiments with Seema Sheth showed that range-edge populations can harbour substantial adaptive variation and responded to artificial selection.
Much of her work involves plant in the genus Mimulus as ecological and evolutionary models.
