Brief synopsis of current research:
The major thrust of my research programme considers the relationship between structure and function in aquatic ecosystems. Structure can be physical, as is the case of rooted aquatic macrophytes in the littoral zone of lakes, or structure can be biological, as is the case when contrasting food webs with different species comprise the communities. Function considers rates of processes that are driven by the nature of the structure. I study structure and function by focusing two related areas. One area considers the role that species and their interactions play in modifying the flow of materials (nutrients, inorganic and organic contaminants) through aquatic food webs. The second area considers alternative stable states in shallow prairie lakes and the ecosystem drivers that cause these lakes to between stable states.

Canada has some of the top aquatic scientists in the world. We share 4 of the Great Lakes with the U.S., and have thousands of smaller lakes, rivers, streams and wetlands in every province and territory that provide ample opportunity to study aquatic ecosystems of different shapes and sizes. We depend on services that aquatic ecosystems provide (clean water for drinking, irrigation and recreation, and water for hydroelectric power generation), thus, understanding how aquatic ecosystems function will be a challenge for many years. I enjoy the challenge of trying to understand how lakes function, and see or learn something new every time I go to the field to take samples.
