Research interests 

After nearly a decade of working in wildlife biology I decided to shift my research focus from wildlife conservation and physiology to human health. Most wildlife problems today are symptoms of human behavior and I believe that physical and emotional health are essential to altering destructive and dissociative human behaviors. My research interests are broad but include the interfaces of mental and physical health, topics related to traumatic experiences (e.g. denial, recovery and resiliency, and impacts to physical health), and alternative therapies that promote human health while fostering a healthier connection to the environment (e.g. gardening, creative arts rooted in upcycling, and environmentally-based service learning).
