Research Focus

Our research group applies biomolecular and biomedical engineering strategies to basic science and translational investigations that address the role of the blood-brain barrier (BBB) in health and disease. We currently employ a wide variety of experimental strategies and techniques, including human pluripotent stem cell (hPSC) differentiation, biomaterial synthesis, microdevice fabrication, and biomolecular/cellular engineering, to carry out our work. For biological investigations, we regularly leverage cell culture (including simple 2D cultures and Transwell co-cultures) for mechanistic interrogations, followed by rigorous follow-up studies in 3D engineered systems, human tissue, and in vivo models of disease. Likewise, we routinely seek to improve engineering platforms and techniques that can be applied back to basic wet lab research, model development, and neurovascular disease treatment strategies. These comprehensive activities are supported by the diverse expertise of our group. We are also highly collaborative and enjoy working with other labs on campus to address difficult biomedical questions outside of the central nervous system.
