Before he joined ASU, he stayed 2 years at Valparaiso University in Indiana for undergraduate teaching. His research works have been mostly done through the support from two NOAA RISA (Regional Integrated Sciences and Assessments) programs in Colorado (WWA, Western Water Assessment) and South Carolina (CISA, Integrated Sciences and Assessments). RISA teams are organized to develop and deliver water/climate related information and research results to various stakeholders through interdisciplinary setup. Active social scientists and policy researchers as well as hydrologists and climate scientists work closely together in RISA teams.
