SPATIOTEMPORAL DYNAMICS OF THE SPINDLE ORIENTATION MACHINERY IN MITOSIS
In this project we address how polarity cues control the organization of the mitotic cell cortex to regulate the spatial and temporal dynamics of the molecular spindle orientation machinery essential to position spindles. We will use the mammalian polarity aPKCs as a paradigm for phosphorylation-dependent events that drive mitosis, spindle orientation and cell fate, as we showed previously that this kinase controls mammalian spindle orientation and cell fate in vivo under homeostatic and pathogenic conditions.

"I completed both my Bachelor`s and Master`s degrees in Molecular Biology and Genetics at the Middle East Technical University in Ankara, Turkey. After gaining neurobiology insides of diseases, I got more curious about the factors influencing cell fate. Currently, I am working in the Niessen Lab, where I aim to enlighten how cell fate and positioning are regulated by cell division during my PhD journey."

"In my Ph.D. studies, I study how the skin forms and maintains its epidermal barrier. Before joining Niessen lab, I completed my BS-MS degree from the Indian Institute of Science Education and Research (IISER), Pune -India in the field of Biology and worked in a research laboratory conducting preclinical research studies on various skin diseases."
