Research Interests
Dr. Ryan Boyles is the Deputy Director of the Southeast Climate Adaptation Science Center (SE CASC), one of eight centers in the United States at the core of the Department of the Interior’s climate change response strategy. He is an applied climatologist focused on using weather & climate science and data to support effective management of natural resources. Ryan is a native of North Carolina and previously served as State Climatologist and Director of the State Climate Office of North Carolina from 2006-2016. Over the past decade, he has lead development of climate datasets, web tools, and climate services targeted for use by human health, agriculture, and natural resource management sectors. These activities focus on the use of historical climate observations to assess the sensitivity of these sectors, experimental forecasting to provide short-term and seasonal guidance, and climate model downscaling to explore the potential changes in longer-term risk. Ryan led the development of more than 40 online tools for climate data search, analysis, visualization and applied decision support. He has received more than $11M is external grant funding between 2007-2016, and has given more than 100 invited community and professional presentations since 2007.
