Biography

Since 2001 Judith Klumperman is professor of Cell Biology and since 2008 chair of the Department of Cell Biology at the UMC Utrecht. She is also head of the Cell Microscopy Core of the UMC Utrecht, which is widely recognized as one of the best expertise centers in the world for immuno-electron microscopy. On a yearly basis the UMC Utrechts trains and assist over 40 scientists from the Netherlands and 15-20 international guests.She is often asked for expert microscopy advise and participate(d) in a large number of international collaborations.

Her research focus on understanding the molecular basis of human diseases, with an emphasis on diseases of the endo-lysosomal system. Diseases specifically addressed in my work are: Lysosomal storage disorders (Pompe disease; Mucolipidosis II/I-Cell disease) – Alzheimer disease – Hermansky Pudlak Syndrome (pigmentation bleeding disorder) - Cancer – virus and bacterial infections – ARC syndrome –Microvillar inclusion Disease. In addition, her work has elucidated fundamental concepts of endosome and lysosome biogenesis, of which the most recent finding is a novel pathway for the delivery of lysosomal membrane proteins to the lysosomes.

Research groups

Advanced microscopy and organelle dynamics

Research aim

We aim to comprehend the complex process of lysosome biogenesis in health and disease. Advancing our understanding holds promise for novel treatments of cancer and neurodegenerative diseases
