My interests have been wide ranging from fieldwork on comparative aquatic vegetation in the Netherlands, India and the former Czechoslovakia for my doctoral work, to modeling toxic impacts on aquatic foodwebs, modeling terrestrial nutrient cycling, modeling contaminated sediment transport in surface waters, and performing uncertainty analyses of various models, including acid deposition models of watersheds while at ORNL. More recently, at PNNL, I analyzed the consequences of introducing renewable energy-based electricity generation in the integrated assessment Second Generation Model after documenting each of JGCRI's integrated assessment models. My interests in systems analysis led to developing JGCRI'svulnerability-resilience model that first was driven by national data and later tested on states in India.
