David R. Ownby

	Associate Professor Environmental Chemistry Office: 514D Smith Phone: (410)704-2946 E-mail: downby@towson.edu Website: http://pages.towson.edu/downby
Education	B.S. Chemistry (1995) Davidson College M.S. Environmental Toxicology (1997) Clemson University Ph.D. Marine Science (2002) The College of William and Mary Postoctoral Fellow (2002-2004) Southern Illinois University - Carbondale
Teaching	Introduction to Environmental Chemistry (CHEM 104) General Chemistry I (CHEM 110) General Chemistry II (CHEM 111) Environmental Chemistry (ENVS 602) Ecotoxicology (ENVS 640)
Research	A general theme present in my research is the goal of developing models and utilizing novel statistical approaches to accurately predict the effects and fate of metals, both singularly and in combination in both aquatic and terrestrial systems. My research addresses issues of how the chemistry of a system affects the bioavailability of metals and the consequential affect of the metal on the organism. More information is available on my webpage.
