My work focuses in the area of environmental contaminant fate and transport modeling, with emphasis in analyzing and simulating the behavior of organic pollutants in urban, remote and industrial areas. My expertise includes environmental sampling, analytical chemistry, statistical analysis and multimedia modeling.

Mainly, I use passive samplers to determine persistence organic pollutants (POPs) in sediment pore water, as well as in air, and look at the partition between sediment and freely dissolved phase. I’m also interested in the soluble release of POPs from the bed sediment to the overlying water.
