My research focuses on the structure and dynamics of aquatic ecosystems, primarily streams and rivers in arid lands. I study temperature dynamics, material transport, nutrient assimilation, hydrology, and the factors affecting metabolic processes of aquatic ecosystems. I led a team of scientists and engineers who developed numeric models that simulate water quality in rivers where periphyton dominates the oxygen and nutrient dynamics. Although most of my past research has focused on flowing surface waters, my scope of interest lately has been broadening to include riparian, wetland, estuarine, and shallow groundwater environments. I often design and assemble novel instrumentation to support measurements of ecological and hydrological processes. These research instruments, for example, enable monitoring of surface water-groundwater exchange, groundwater flow, and measuring aquatic community metabolism and nutrient dynamics in flowing mesocosms. I currently am involved in integrating field instruments with software tools to facilitate research at remote sites using web-based data collection and graphical display.
