Membrane trafficking group

Academic Interests
My research focuses on the interplay between membrane dynamics, signaling, and the cytoskeleton, with a special emphasis on phosphoinositide lipids and lipid-binding proteins. I am particularly interested in how these components regulate vesicle trafficking and cellular organization. My group investigates macropinocytosis and endocytic recycling, focusing on how vesicles establish and maintain their identity through phosphoinositides and Rab GTPases. Using advanced imaging techniques, we explore vesicle dynamics in processes such as nutrient scavenging in cancer cells.

Current Research Focus

  1. Macropinosome Formation: Investigating how macropinosomes form, establish their identity, and are exploited by cancer cells and pathogens.
    • Key findings include a Rab and phosphoinositide switch during vesicle maturation, with implications for membrane trafficking.
  2. Nutrient Scavenging in Cancer: Understanding how macropinocytosis supports tumor metabolism, with a focus on KRAS-driven cancers and potential therapeutic targets.

Technological Expertise:

  • Advanced microscopy (light sheet, super-resolution, live-cell imaging)
  • Tracking and manipulation of phosphoinositides
  • Development of optogenetic and synthetic biology tools for lipid and protein manipulation.
  • Image analysis and deep learning for biological imaging.
