Our primary research interests are process dynamics in environmental systems, focusing on chemical emissions from building materials and consumer products and water quality in lakes and reservoirs.  A more recent focus is the management of complex societal challenges using an evolutionary, system-of-systems approach.

We collaborate with many international research groups and I have been a visiting professor at National Cheng Kung University in Taiwan, Swiss Federal Institute for Aquatic Science and Technology (Eawag) in Switzerland, Tsinghua University in China, University of Granada in Spain, University of Sydney in Australia, and Scientific and Technical Center for Building (CSTB) and University of La Rochelle in France.
