Research Interests:

Our goal is to understand the structure and function of cotransporter proteins. These are responsible for the active transport of molecules and ions into cells. Specifically, we study sodium glucose cotransporters (SGLTs). We use a combination of biophysical, biochemical, molecular, and structural, techniques to unravel how these molecular machines convert the energy stored in sodium gradients to drive the uphill transport of solutes. We also study genetic diseases of SGLTs where our goal is to determine how mutations cause transport defects. The cotransporters are expressed either in Xenopus laevis oocytes and mammalian cells for biophysical and biochemical studies, and Escherichia coli for the isolation of protein for structural studies. We are now imaging SGLT function in human subjects.
