We are always looking for students with strong physics and mechanics background to join my multidisciplinary research group. Students can choose to study either in the Geotechnical Engineering and Geomechanics track or the Engineering Science track in the CEAE department. The former focus more on applying geomechanics to geotechnical and energy geotech problems. The Engineering Science track focus more on the physics of porous and granular materials with the goal of advancing fundamental science. Those interested can send their detailed resume to Yida.Zhang@Colorado.edu. The email should include a brief description of research background and interests.

The deadline for graduate student applications is typically in early December. More information on the graduate student application process can be found on the Department website. Graduate student applicants are also encouraged apply for external fellowships, such as those available from the National Science Foundation Graduate Research Fellowship Program.
