Current Research

* Examine interactive impacts of herbivory by biological control agents and drought on the competitive dominance of a notorious weed.* Asses a new technique for assessing habitat quality for songbirds based on local song structure. * Measure effects of herbicide treatments aimed at weed control on plants and animals and evaluate degree to which such methods mitigate target invader impacts.

Research Interests

My primary interest lies in building understandings of ecological patterns and processes in order to improve the management of natural systems. Current applications include evaluating impacts of exotic weed invasion on native plants, cascading effects on consumers, and efficacy of weed control tools in mitigating these impacts. Studies consider population and community level attributes and organisms from plants and invertebrate to birds and their predators.

Past Research

My past research includes examination of disturbance effects on harbor seals, edge effects of forest roads on songbirds, and habitat use of Canada lynx.

Why This Research is Important

My work aims to develop and use ecological principles and insight to solve real-world problems facing managers of natural systems.
