Research:

My current research interests concern the ecology of arctic lakes and urban streams.  My students and I conduct field work at Toolik Lake, Alaska, and in regional streams. Current projects include the effects of landscape controls of arctic lake productivity, the effects of stream restoration on nitrogen processing in urban streams, and the effects of stream restoration on fish and invertebrate communities in urban streams.
