• Disturbance and Forest Ecosystem Health

    My research focuses on how forest disturbance influences plant metabolism and forest ecosystem dynamics.

    Current projects: 1) survival and competitiveness of blight-resistant American chestnut backcrosses on reclaimed surface mines, 2) impact of hemlock woolly adelgid infestation on ecosystem C cycling in late successional eastern hemlock forests, 3) effects of extreme drought on southern pine water relations and carbon metabolism.
