Brian Railing

Brian Railing is an assistant teaching professor in the Computer Science Department. His technical research interests are the efficient instrumentation and analysis of parallel programs using architecture and compiler techniques.

He also continually studies and analyzes his teaching, as part of a continual effort to improve student learning and the efficiency of their classroom experience. This effort focuses on the usage of active learning techniques in systems courses.

He likes to play soccer, bicycle, and climb mountains. And take photos too.

He can be contacted at bpr at cs dot cmu dot edu.

He maintains a blog, Elegant C, which reflects his own personal opinions and experiences in Computer Science.

Possible student research projects are maintained in a wiki.
