The Team

The Carbonshed Lab welcomes applications from highly motivated students to join our lab at the Ph.D. level. If you have a M.S. degree (or equivalent research experience) and if you are already fluent in GIS, computer programming, and MATLAB, please contact Diego for details. The earlier you contact us (e.g., 6 mo or 1 yr in advance), the better, as it will give us a chance to seek funding together.  Send along your CV and a two-page research statement.

Why get a Ph.D.?
Read this excellent graduate school survival guide written years ago by a former graduate student at UNC-Chapel Hill.


  • Diego Riveros-Iregui received his B.S. in geosciences from the Universidad Nacional de Colombia (1999), M.S. in geology from the University of Minnesota (2004), and Ph.D. in ecology and environmental sciences from Montana State University (2008). He was a post-doctoral fellow at the University of Colorado Boulder (2008-2010) and an assistant professor at the University of Nebraska (2010-2013) before relocating to UNC (2013-present).
