Darius Semmens
Darius Semmens is a Research Physical Scientist with the Geosciences and Environmental Change Science Center
His current research interests include the development of new methods and tools for the assessment and valuation of ecosystem goods and services - the specific benefits that we derive from nature. More specifically, his work involves developing methods and tools that can account for the spatial and temporal dynamics of service production and incorporate that and other information into more rigorous analyses of the tradeoffs associated with landscape management. Darius' current work includes cultural ecosystem services modeling with the Social Values for Ecosystem Services (SolVES) tool, quantifying ecosystem service flows from migratory species to inform cross-jurisdictional management and conservation, and multi-resource analysis for energy and minerals.
