Jae-Hwang Lee

Assistant Professor

Mechanical properties of individual cells are determined by a specific composition and an arrangement of sub-cellular organelles. Since cells can be viewed as heterogeneous polymeric materials exhibiting strain-rate dependent mechanical properties, we are interested in cells’ nonlinear mechanical responses in high-strain-rate regimes and the development of high-strain-rate biomechanical characterization methods.

Current Research
In order to apply HSR mechanical stimuli to a single cell, we are trying to employ a recently developed micro-ballistics technique that can produce a high-speed collision of a single micro-particle to a target specimen. Utilizing extreme mechanical stimuli from the microscopic collision, we are trying to differentiate any subtle difference in the intrinsic mechanical properties of individual cancer cells.
