Flaxen Conway in College of Liberal Arts
Flaxen Conway conducts research, education and engagement about how changes in natural resource policy and management effect industries, workforces, agencies, communities, groups and families that directly depend on them. She specializes in helping individuals and groups adapt to change through cooperative learning, accessing resources, building coalitions and planning strategies that meet the needs of all interests.
