Research interests

My research activities are primarily focused on two general areas: (1) conversion of waste into energy, and (2) characteristics, fate and transport, and treatment of surface runoff pollutants.  Major research topics of interest include:

–       Particle-bound organic and inorganic pollutant characterization;

–       Mathematical modeling of roadway runoff pollutants;

–       Source identification of non-point source pollutants from environments;

–       Innovative stormwater runoff treatment;

–       Permeable pavement for stormwater runoff management;

–       High-solids bio-gasification of organic waste for energy recovery; and

–       Methods to assess the biodegradability of organic wastes for bio-fuel production.
