Research Interest:

Aria’s areas of research interest are aquatic chemistry and contaminant transport, and in particular, the study of speciation and transport of metals and nutrients, and their interactions with mineral surfaces and natural organic matter in natural and engineered systems. Present focus is on the internal phosphorus cycling in temperate lakes, development of the diffusive gradient in thin film (DGT) device as a biomonitoring tool for mercury bioavailability, fate and transport of mercury in lakes and wetlands, and development of catalysts for photodegradation of contaminants. Prior to coming to the University of Maine in fall 1997, Aria was a postdoctoral research fellow at the Swiss Federal Institute of Environmental Science and Technology (EAWAG). He is a cooperating professor with the Chemistry Department, and the School of Policy and International Affairs at the University of Maine. He has been a visiting professor at the Division of Soil Protection, Institute of Terrestrial Ecology (ITÖ), Swiss Federal Institute of Technology (ETH-Zürich) (5/98-9/98), and at the U.S. Geological Survey, Menlo Park, CA, USA (1/04-9/04; 1/11-9/11). Aria has five years of professional experience as an environmental and water resources engineer in the public and private sectors, and is a registered Professional Engineer in the State of California. In addition to his teaching and research duties, he has performed consulting on environmental issues for public agencies and private companies.
