Andy Riesgraf is a Researcher Scientist at SAFL. For this project, he leads the daily fieldwork logistics and activities. Andy brings years of experience in boat operations, fabrication of data logger apparatuses, and their deployment in the field.  Andy is interested in how this data might be informative to impacts on bottom sediments, aquatic vegetation, and fish population dynamics. 

William Herb, PhD, is a Research Associate at SAFL. His research includes hydrology, lake and stream water quality, fish habitat, and climate change. His current projects include a study to predict the size distribution of wind-generated waves on Minnesota lakes.

Jessica Kozarek, PhD, is a Research Associate at SAFL. She conducts experiments linking physical, chemical, and biological processes in aquatic ecosystems in the lab and the field. Her research interests are in the areas of aquatic ecosystem restoration and management; ecohydraulics; use of hydraulic models to develop restoration guidance; and water quality and nutrient dynamics.

Matt is an Associate Engineer at SAFL and has over 15 years of experience in applied and basic hydraulic research. His research is primarily related to the measurement of flow, forces, and sediment transport near structures like bridge piers, scaled models of hydraulic structures, and wind turbines. For this project, Matt brings knowledge of fluid dynamics and measurement methodologies.
