Research interests
The aim of my research is to gain a stronger understanding of how the cytoskeleton is regulated during cell division, migration and polarity. I am interested in how microtubules and actomyosin control these events during cell division, and how they are hi-jacked in cancer cells. This includes an in depth molecular analysis of anillin, a highly conserved protein that is required for cytokinesis and crosslinks key components of the cell. I use cultured human cells including cancer cell lines and iPSCs as model systems. I also collaborate with other groups to develop delivery and diagnostic tools for cancer cells, and to develop anti-cancer drugs.
