    Research Interests

    Our laboratory explores the role of neuronal energy metabolism in physiologic and pathologic blood vessel growth. Understanding the drivers of abnormal vessel growth is key to controlling many diseases of the eye and cancer. In the retina, the oxygen and energy demands of neurons govern blood vessel growth. Although much is known about oxygen drivers of vessel development, surprisingly little is known about the neuronal energy signals that are also likely to control vessel growth. Our laboratory uses transgenic mice to study the driver of angiogenesis in models of proliferative retinopathy and age-related macular degeneration (AMD), together the leading cause of blindness. The eye is part of the central nervous system and consumes more energy than any other organ. It is therefore an excellent model in which to explore the metabolic crosstalk between neurons and vessels to discover new therapeutic targets.

    Research Topics

    • Angiogenisis
    • Neuro-vascular guidance
