Dr. Characklis is a professor in the Department of Environmental Sciences and Engineering at the University of North Carolina at Chapel Hill. He also serves as director of the Center for Watershed Science and Management within the UNC Institute for the Environment.
His primary research interests involve developing solutions to environmental challenges through systems-based approaches that integrate consideration of both engineering and economic principles. Specific areas of interest include the development of improved strategies for managing water supply and treatment systems, exploration of the economic and environmental trade-offs associated with energy production (e.g., hydropower, biofuels) and the management of environmental financial risks.
Dr. Characklis also has directed a number of laboratory and field studies that explore the role particles play in microbial transport, research with particular relevance in the development of water quality models used to evaluate the location and severity of microbial contamination.

In this work, a relationship between water levels and shipping revenues is developed and used in an actuarial analysis of the frequency and magnitude of revenue losses. This analysis is used to develop a standardized suite of binary financial contracts, which are indexed to water levels and priced according to predefined thresholds.
This paper presents a short history of water resources systems analysis from its beginnings in the Harvard Water Program, through its continuing evolution toward a general field of water resources systems science.
This study uses an integrated hydro-economic model of the Roanoke River Basin to characterize the financial risk faced by hydropower generators as a result of hydrologic variability, and develops several index-based financial hedging contracts intended to mitigate this risk.
Examples include Robust Decision Making (RDM), Decision Scaling, Info-Gap, and Many-Objective Robust Decision Making (MORDM). We propose a taxonomy of robustness frameworks to compare and contrast these approaches based on their methods of (1) alternative generation, (2) sampling of states of the world, (3) quantification of robustness measures, and (4) sensitivity analysis to identify important uncertainties.
Despite the potential for hydroelectric dams to help address challenges related to the variability and unpredictability of wind energy, at present there are few systems-based wind-hydro studies available in the scientific literature. This work represents an attempt to begin filling this gap through the development of a systems-based modeling framework for analysis of wind power integration and its impacts on hydropower resources.
