Dr. Kirwan, Associate Professor, is a geomorphologist with expertise in how vegetation and sediment transport influence the response of coastal landscapes to sea level rise. His research focuses on applying concepts of eco-geomorphology to better understand: 1) carbon-climate feedbacks in the coastal zone, 2) the response of wetlands to sea level rise, enhanced CO2, and elevated temperatures, and 3) how humans influence wetlands through upland land use change and its effect on wetland migration and sediment delivery to the coast.
