My lab group works on many aspects of stream ecology but mainly focus on the role that microorganisms such as algae, bacteria, and fungi play in regulating stream ecosystem function and how human impacts can alter these dynamics. We are currently engaged in several projects that focus on the role that stream microorganisms play in stream nutrient dynamics and ultimately the export of these nutrients to larger rivers and estuaries. We are specifically interested in how stream algae and bacteria respond to pulses of nutrients associated with runoff and how adjacent land-use modifies these responses.  We are also investigating how targeting conservation efforts lead to improved water quality and enhanced ecosystem function.
