Moving Beyond Implications: Research into Policy Inaugural Conference

Posted on by

UConn Tech Park responded to a call for researchers to shape policies that optimize benefit to Connecticut’s communities, environment, and economy. Interim Executive Director Emmanouil Anagnostou and Professor George Bollas, along with other researchers and academicians, participated in the inaugural “Moving Beyond Implications: Research into Policy” conference at the State Capitol. This event fosters collaboration between policymakers and researchers, promoting evidence-based policymaking in the state. Anagnostou and Bollas presented topics related to the impact of extreme rainfall on water infrastructure and non-carbon-based fuels, respectively, contributing to the dynamic discussion on how scientists can inform future policy decisions for impactful results.

Check out the UConn Today article, “Conference to Unite Legislators and Scientists in Joint Effort to Strengthen Connecticut” for additional details on the conference’s objectives and background.

Co-organizers State Rep. Jaime Foster and Kerri Raissian provide post-conference commentary in the CT Mirror article, “For progress, put Connecticut lawmakers and researchers in the same room.”
