Research Interests

Our lab studies central nervous system (CNS) injury mainly in the retina and brain. The lab employs different molecular/cell culture techniques, human tissue samples, and animal studies to model critical disease conditions in these two organs. Among the diseases under study are diabetic retinopathy, retinopathy of prematurity, traumatic optic neuropathy, traumatic brain injury, and stroke. Our studies aim to elucidate the underlying pathological mechanisms in these conditions and identify new therapies that can be translated from bench to bedside to help patients affected by these disease conditions.

We are interested in studying immune cells in CNS diseases with a special focus on the role played by myeloid cells (macrophages and microglia) as they respond to acute and chronic injury to the retina and brain. These cells closely interact with CNS neurons and vasculature and therefore play a major role in neurovascular injury and repair. Our goal is to gear the myeloid cells toward a reparative phenotype through modulation of different molecular pathways. The lab is funded by the National Eye Institute.
