Biography of Randy Maddalena

Randy Maddalena, Ph.D., is a Research Scientist in the Indoor Environment Group with the Environmental Energy Technologies Division at Lawrence Berkeley National Laboratory. He received his BS in Environmental Toxicology (1992) and Ph.D. in Agricultural and Environmental Chemistry (1998) from the University of California, Davis.

The focus of his research at LBNL is on environmental fate and transport processes and multi-pathway exposure assessment for organic chemicals combining modeling, bench scale experimentation and field observational studies. Randy's research supports the development, evaluation and application of mathematical models that predict chemical fate in multiple environmental media (air, water, soil, vegetation, sediment) and chemical exposures through multiple pathways (drinking water, food, feed, indoor air, dust) for both human and ecological receptors. His recent research has focused on characterizing indoor pollutant emission sources including office equipment, identifying sources of indoor pollutants in FEMA trailers, characterizing exposure concentrations of insecticides used on passenger aircraft, developing sampling and modeling tools for assessing indoor exposures to semi-volatile organic compounds, characterizing sulfur gas emission from Chinese drywall and quantifying particle emission from Mongolian space heating stoves. Other research projects focus primarily on indoor air quality measurements and the development of environmental sampling and analytical chemistry methods to support research on the fate and exposure characterization for a range of pollutants.
