Lucy Kerhoulas

Assistant Professor - Forest Ecophysiology

I study ecophysiology in coniferous forests. My research investigates the relationships among water use, growth, physiology, climate, and forest management. I use stable isotope analyses, dendrochronology, and gas exchange measurements as my primary research tools. Learn more about my research by visiting Forest Physiology Lab.
