Advisor: Wendy Thomas, Ph.D. (Department of Bioengineering)

Project: Development of a novel protein-based force sensor for use in detecting and measuring tensile mechanical forces related to cellular adhesion. Focused on the design of an in vitro testing system to selectively apply forces to the chimeric fluorogen-activating protein and visualize the resulting changes in fluorescent signal.
