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.
