Callan Luetkemeyer is a Ph.D. candidate in the Department of Mechanical Engineering and a member of the Mechanics of Materials Laboratory. Her research uses state-of-the-art, full-field experimental and computational inverse techniques to build mathematical models of the mechanical behavior of the anterior cruciate ligament (ACL), a commonly injured knee ligament. These models are intended for use in whole-knee finite element simulations to study the effects of potential injury risk factors and surgical reconstruction techniques. To achieve this, Callan adapted a computational inverse technique, the virtual fields method, for use with full-volume data, spatially-varying fiber directionality, and nonlinear boundary conditions.
Callan is also a focus group activity organizer for the Girls in Science and Engineering (GISE) camp. She plans to pursue a postdoctoral position after defending her dissertation in fall of 2019.
