We study a small organelle on the surface of cells known as the primary cilium. The majority of your cells in your body have a primary cilium, including all of your neurons and stem cells. This organelle is small but mighty, being less than 1/3,000th of a cell’s volume, yet cilia are essential for our development. These organelles are full of signaling molecules, including membrane bound receptors are specially recruited into the cilium and have unique control over cell fate and signaling. I study how these organelles regulate our metabolic health.
