Curriculum Vitae



The identity and function of cellular organelles critically relies on information encoded in their lipid bilayers. In the Holthuis lab, we study the functional implications of, and compensatory cellular responses to disease-induced imbalances in organellar lipid codes, with a main focus on aberrant distributions of sphingolipids. As approach, we develop disease-relevant cell models and exploit functionalized lipid probes to interrogate organellar lipid codes and capture novel lipid effector proteins.
