Neal Blair

Professor, Joint Appointment in Civil & Environmental Engineering

Ph.D. Organic Chemistry, Stanford University
B.S. Chemistry, University of Maryland
Curriculum Vitae


My research has focused on the biogeochemical transformations of carbon with an emphasis on process-oriented studies of the fate of organic carbon in surface environments. The evolution of Critical Zone C as it moves across the surface of the Earth is a particular focus. Anthropogenic impacts on the global C-cycle via land use and hydrologic engineering are being investigated.
