Mariana Osswald
Epithelial Polarity & Cell Division
Junior Researcher
Mariana Osswald studied bioengineering at the University of Porto. After completing her MSc degree in 2012, she worked on mitosis in the group of Claudio Sunkel at the IBMC in Porto. In 2015, she joined Eurico Morais de Sá’s group at IBMC/i3S for her PhD on cell polarity and cell division in epithelial tissues. She is currently conducting post-doctoral research at this group, aiming to understand mechanisms that ensure tissue architecture and integrity in proliferative epithelia.
