Professional Activities:

Entomological Society of America, American Phytopathological Society, Western Weather Systems Workgroup (funded by W. Region IPM Center), USDA National Plant Diagnostics Network, Western Extension Research Activity (WERA) 102 – Climatic Data and Analyses for Agricultural and Natural Resources

Chief developer and supervisor of OSU IPPC’s website “IPM Pest and Plant Disease Models and Forecasting for Agricultural, Pest Management, and Plant Biosecurity Decision Support in the US“, http://uspest.org/wea which serves thousands of users in agricultural and pest management decision support in the U. S. The site integrates real time weather data from 17,000+ weather stations, PRISM climate data, GRASS GIS, spatial interpolation of weather data and models, 100+ crop, pest and disease models, and site-specific and gridded forecasts from Fox Weather, LLC and the NWS.

Working with Jeff Stone (OSU Forest Pathologist) to predict how climate change affects PNW forests under pressure from the Swiss needle cast disease.

Coop and IPPC are providing generic and custom phenolgy maps, and pest modeling expertise, to the National Plant Diagnostic Network, the Great Plains Diagnostic Network, and to USDA APHIS PPQ, to support pest modeling and monitoring programs for invasive species. Coop is providing phenological expertise to model emergence of native threatened and endangered butterflies (Fenders Blue and Silverspot Butterfly), in collaboration with the Nature Conservancy, the Xerces Society, and the Greenbelt Land Trust.

Served on numerous graduate student committees, more than 15 total to date and more than 8 since 2011 as a Graduate School Committee Representative.
