Technology adoption and voluntary approaches to pollution control; welfare analysis of alternative policy instruments for environmental protection; economic, land use and environmental implications of biofuels; policies for carbon sequestration.

Boundary Layer and Mesoscale Meteorology; Multi-Scale Study of Lake Breezes and the Impact of Marine Boundary Layers on Convection in the Great Lakes Region. Effects of Non-Uniform Surface Conditions on Lake-Effect Systems; Climatic changes in Great Lakes precipitation.

Main research interests focus on the microbial ecology and molecular microbiology aspects of water and wastewater treatment processes. This is based on the facts that the microorganisms are the key catalyst for wastewater treatment, and the primary causative agents for the failure of water purification systems and the occurrences of infectious diseases.

Current research includes the effects of climate change on hydrologic systems in urban and agricultural areas of the Midwest, and the Great Lakes region. Is interested in statistical downscaling of global climate modeling outputs, extreme rainfall, extreme floods and droughts under the future climate scenarios. Other interests include the past and future trends in water contaminants, riverine nutrient load estimation methods, as well as real-time water quantity and quality forecasting in the streams and rivers in the Midwest and the Great Lakes region.
