My goal is to develop students' technical and communication skills through coursework and research related to understanding how environmental contaminants are transported and transformed during transient changes to redox interfaces.  Our projects answer scientific questions that will further the development of tools for managing risk from environmental contaminants.    

I have working relationships with state and federal resource management agencies interested in sulfate discharges to freshwater resources in northeastern Minnesota, sediment contamination in the St. Louis River Estuary, and mercury in lakes and rivers.  
 With appointments in the UMD Civil Engineering U of MN Water Resource Science graduate programs, I am always looking for curious, motivated graduate students to join our group and typically have a several undergraduates involved in UROP projects and working in the lab.
