About me:
Ben completed his M.S. degree in the Groves Lab and is continuing on in the lab working on a variety of projects, including the upkeep of this website. During his time as a graduate student, he explored the problem of groundwater contamination by neonicotinoid insecticides, specifically thiamethoxam, by surveying high-capacity irrigation wells in the Central Sands vegetable growing region of Wisconsin. In addition to describing the spatial extent and magnitude of this contamination, his thesis explored of the relationship between neonicotinoid contamination and landscape composition in the vicinity of sampled wells. Prior to moving to Wisconsin to pursue a degree in Entomology, Ben worked with the USDA-ARS Aquatic and Invasive Weeds Research Unit in Davis and Albany, CA.
Research interests:
In the Groves Lab our research focuses primarily on applied aspects of pest management in commercial vegetable crop production in Wisconsin. We also study related questions surrounding the environmental fate of insecticides and issues of surface and groundwater quality and relationships to land use and agricultural intensity. In partnership with the Vegetable Pathology lab of Amanda Gevens, we have also developed several map-based web tools for predicting disease and insect risk using daily gridded weather data (VDIFN and AgWeather). I am also particularly interested in creating interactive web interfaces for connecting participants in citizen science projects with the data they help collect, such as with the WiBee pollinator survey project, and the Water Action Volunteers stream monitoring program.
