For almost 20 years, Dr. Scott Ogle has been directing and/or participating in research in the areas of aquatic ecotoxicology and environmental chemistry. A major area of Dr. Ogle's past research efforts has focused on factors affecting toxicity and bioaccumulation of selenium to algae, invertebrates, and fish and have established him as an expert in this field. Current research activities include evaluation of the fate and effects of metals, pesticides, and petroleum and petroleum products in the aquatic environment, monitoring and investigation of contaminants and toxicity in ambient waters, point-source and non-point source discharges, stormwater runoff, and TMDL development. Dr. Ogle is also an expert in all aspects of freshwater, estuarine, and marine sediment toxicity and bioaccumulation issues, and has served as Lead Instructor for the SETAC sediment toxicity professional short course at the regional and national level. Dr. Ogle has directed and participated in numerous projects encompassing all of the standardized EPA and ASTM test procedures as well as projects involving development of new testing procedures. Performance of all of these projects has involved a leadership role by Scott, from conception and design of experimental approach, through completion of studies and analyses of results, and finally, reporting of the results to the concerned parties. Selected projects which have involved a leadership role by Dr. Ogle include:

	monitoring of ambient water toxicity in a variety of ecosystems;
	evaluation of sediment toxicity in a variety of ecosystems;
	development of site-specific water criteria for several trace metals, including selenium;
	evaluation of petroleum and petroleum product toxicity to aquatic organisms;
	evaluation of surface/stormwater runoff toxicity;
	NPDES toxicity evaluations;
	single species and food chain bioaccumulation studies;
	biomonitoring of bioaccumulation in contaminated field systems;
	toxicity and bioaccumulation testing for ecological risk assessments;
	fate studies for various trace elements;
	literature reviews on a wide variety of water pollution problems;
	critical review of technical reports and proposed regulatory actions.
