Research Interests

  • My laboratory performs research in the area of lymphatic vascular biology to gain insight into how loss of lymphatic vessel function leads to disease. Specifically, we use a unique combination of genetic and physiologic approaches to quantify lymphatic vascular permeability, which allows us to assess fluid and solute transport across the lymphatic vessel wall. Diseases associated with leaky lymphatic vessels include obesity, type 2 diabetes, hypercholesterolemia, lymphedema, and infection. Our research is multidisciplinary as we routinely collaborate with investigators from physiology, immunology, and developmental biology areas. Some current areas of interest are:
  • 1)The physical pathways and molecular regulators that restrict solute and fluid loss across the lymphatic vessel wall, preventing edema.
  • 2)The role of lymphatic vascular permeability in immune cell trafficking to the lymph node.
