My research interests include the neurovascular unit and brain development and the use of cutting-edge strategies to investigate neural-vascular interactions. The vasculature is emerging as a key contributor to brain function during neurodevelopment and in mature physiological and pathological states. During my PhD, I developed a widely applicable protocol based on Fluorescence Activated Cell Sorting (FACS) to isolate endothelial cells and pericytes from micro-regions of the adult mouse brain and studied the effects of these cells on different stages of the neural stem cell lineage. These experiments determined that factors from endothelial cells and pericytes from regions of the adult brain that do not harbor stem cells can still support key neural stem cell behaviors, such as proliferation and the production of new neurons.
This work has exciting implications for brain plasticity. In my current work, I am studying the role of blood vessel cells in brain development during physiological and pathological states. These studies also have relevance to neonatology as extremely premature infants are vulnerable to life threatening brain hemorrhage. Despite the severity of this condition, its mechanism remains unknown. To fund my research, I have been awarded fellowships from the Edythe and Eli
Broad Regeneration and Stem Cell Fellowship and the Pediatric Scientist Development Program.
