Angiogenesis (the generation of new blood vessels from pre-existing ones) is a highly synchronized process requiring the coordinated efforts of several vascular and non-vascular cell populations and a stringent orchestration by the tissue being vascularized. Stereotyped angiogenesis is vital for both developmental growth and to restore tissue oxygenation and metabolic supply following vascular injury.

Given that angiogenesis becomes deregulated in numerous pathological contexts such as cancer and ischemic neuropathies, it is key to understand the molecular and cellular mechanism that ensure sound vessel growth. Our laboratory studies angiogenesis with a focus on ocular vascular systems. We tackle these diseases by studying vascular growth and the factors that regulate it. Moreover, we are interested in the cellular interactions and intracellular mechanisms that govern vessel growth in both physiological and pathological contexts.
