Theodore D. Tomasi, Ph.D.

Managing Principal (856) 399-7725 moorestown, NJ ttomasi@integral-corp.com

Dr. Ted Tomasi has more than 30 years of experience as a natural resource economist, specializing in the valuation of natural resources and environmental changes, risk management in the context of use decisions regarding resource use, and benefit–cost analysis. Before beginning his consulting career, he served on the faculties of the University of Minnesota, University of Michigan, and Michigan State University, where he taught and conducted research on environmental policy analysis, decision-making under uncertainty, and methods for valuing ecosystem services. For the past 20 years, Dr. Tomasi has been a consultant to large private companies on environmental decision-making, including issues related to net environmental benefits of remedial decisions, the value of information in managing risks, and liability management in environmental damage cases. He has provided litigation support and expert testimony on natural resource values in numerous such matters, large and small. Among Dr. Tomasi’s other projects are climate change and carbon sequestration evaluations, sustainability in agriculture and non-point pollution control, valuing the conservation of land, and evaluating restoration and mitigation/offset programs.

Dr. Tomasi served as an advisor and economic expert for NOAA’s Damage Assessment Center and sat on expert review panels for the Type-A natural resource damage assessment (NRDA) model for both the Great Lakes and the coastal and marine environments. He has published numerous book chapters and peer-reviewed journal articles, and is a sought-after speaker in the area of environmental damage claims.
