Robert E. Ulanowicz, Ph.D., Project Coordinator
	Robert E. Ulanowicz is Professor of Theoretical Ecology with the University of Maryland's Chesapeake Biological Laboratory. He is a 1961 graduate of the Baltimore Polytechnic Institute and received a B.E.S. and Ph.D. in Chemical Engineering from the Johns Hopkins University in 1964 and 1968, respectively. He served as Assistant Professor of Chemical Engineering at the Catholic University of America before joining the Chesapeake Biological Laboratory in 1970. He is fluent in German, conversational in Ukrainian and has a reading knowledge of Polish, French and Spanish. Earlier at CBL, Prof. Ulanowicz pursued research into the estuarine hydrography of Chesapeake Bay and on methods for inverse modeling of ecological systems. His current interests include network analysis of trophic exchanges in ecosystems, information theory as applied to ecological systems, the thermodynamics of living systems, causality in living systems, and modeling subtropical wetland ecosystems (ATLSS).

Sheila Heymans, Ph.D., *Research Associate/Data Analyst*
	Sheila Heymans is a Post Doctoral Fellow in the Fisheries Centre (UBC) with experience in ecosystem model construction of marine, freshwater and estuarine systems. Dr. Heymans earned her Ph.D. in 1997 from the University of Port Elizabeth in South Africa, when she constructed an ecosystem model of the Northern Benguela Ecosystem off Namibia. She has completed a Post Doctoral study on the graminoid marshes of the Everglades at the Chesapeake Biological Laboratory in Maryland and is currently working on the Back To the Futures Project for which she is constructing models of the Hecate Strait and Newfoundland ecosystems.

Cristina Bondavalli, Ph.D., *Research Associate/Data Analyst*
	Cristina Bondavalli received both her AB and Ph.D. from the University of Parma, Italy. While a student there, she conducted studies on matter and energy flow in estuarine ecosystems with particular emphasis on the role of seston and on the interactions between water and sediments. She has also been involved in studies concerning macroalgae decomposition and related effects on trophic status of the Po River Delta. Her dissertation research focused on the circulation of radionuclides with the aim to understand the degree of contamination of the Po River Delta, and to study how such elements cycle within the trophic structure, earning her Ph.D. in 1994. Dr. Bondavalli currently resides in Italy.

Michael S. Egnotovich, Graduate Student, Data Manager/Webdesigner
	Michael Egnotovich is a graduate student at the University of Maryland, currently working on a project investigating the effects of nutrient enrichment and sedimentation on the plant communities of tidal freshwater wetlands of the Nanticoke River, Maryland, USA. His disseratation is focusing on the interactions among the biotic and abiotic components of the marshes in these wetlands and how they relate to ecosystem health. He has a B.S. in Wildlife and Fisheries Biology from the Pennsylania State University, and a B.A. in American History from Fordham University.
