Self-introduction
Our main research interests are the molecular mechanisms of mitotic progression, particularly we focus on the mechanism of spindle microtubule formation which is required for proper chromosome segregation. For this purpose, we usually use yeast as a model organism. We also aim to apply our findings towards the development of novel anti-cancer drugs.
