Faculty Profile
Rosen Laboratory

The Rosen Lab studies the physical mechanisms of actin regulation. We seek to understand both the structure and dynamics of individual pathway components and also how and why those components are organized into micron-scale cellular assemblies. 

Elliot Ross, Ph.D.

Elliot Ross






Professor of Pharmacology
Greer Garson and E.E. Fogelson Distinguished Chair in Medical Research

Ph.D., Biochemistry, Cornell University

Faculty Profile
Ross Laboratory

Dr. Ross' group studies how cells process information, particularly through heterotrimeric G proteins: the molecular mechanisms used to detect, sort, amplify, and convey information, and how these mechanisms are regulated to provide G protein signaling modules with adaptability and diversity.
