I am interested in understanding how nutrients from the food we eat shapes gastrointestinal function and health. My lab is currently focused on nutrient-sensing G-protein coupled receptors on epithelial cells lining the gut and how they can alter gut hormone release and gastrointestinal inflammation. This work has implications in understanding the influence of gut microbiota in human health, and how the gut signals to the brain to control our eating habits.

Techniques in the lab: We use a combination of cutting-edge molecular approaches and classical electrophysiology techniques to investigate ion channel modulation by G-protein coupled receptors.

  1. Electrophysiology
  2. Calcium and cAMP imaging, confocal microscopy
  3. Intestinal organoids models
  4. CRISPR gene editing
  5. Molecular biology, RT-qPCR
  6. Bulk and single-cell transcriptomics
  7. Immunostaining, ELISA
