Sonia Colombo


Assistant professor in Molecular Biology at the University Milano-Bicocca.

Research activities and skills

Stress resistance (e.g. oxidative and osmotic stress), apoptosis, cell cycle regulation and molecular mechanisms of signal transduction in eukaryotes, in particular in the yeast Saccharomyces cerevisiae. Yeast models can play an important role, since the findings in yeast can be interpolated to humans. She is also involved in single cell techniques to study signal transduction pathways. Molecular and cellular biology techniques and flow cytometry assays are some of the approaches used in her laboratory.
