Cardiovascular Bioengineering Laboratory

The central theme of the Cardiovascular Bioengineering Lab's research program is primarily on hemodynamics and mechanobiology via the application of biomechanics and biomedical optical imaging principles and techniques. Using light-sheet microscopy, Dr. Lee is investigating the mechanisms whereby hemodynamics regulates the development of the ventricular chamber. His group is linking the effects of hemodynamic forces on developmental biology to understand the mechanisms of development and heart regeneration using the zebrafish animal model. The goal of our research is to translate our findings to higher levels of animals in collaboration with UT Southwestern Medical Center.

Research projects in the Cardiovascular Bioengineering Lab include:

• Hemodynamics and Cardiac Development
• Intracardiac Hemodynamics and Tissue Mechanics
• 4-D Beating Zebrafish Heart with Light-Sheet Microscopy
• Ultramicroscopy with Super-Resolution
