Giulia Rancati

Giulia Rancati is a cell and evolutionary biologist. She is Senior Principal Investigator at the Institute of Medical Biology, A*STAR and Principal Investigator at the Biotransformation Platform for Innovation, A*STAR, Singapore. In 2011 she was awarded the A*STAR Investigatorship and in 2017 she become an EMBO Young Investigator. Among her scientific contributions, she showed how eukaryotic cells adaptively evolve in response to extreme genetic perturbations and the consequences of large-scale genome changes on the cellular phenotype.

We are fascinated by evolvability, which is the remarkable capacity of cells to adapt to a variety of hostile conditions. In out lab we combine cell and systems biology approaches to understand cellular evolvability in mechanistic terms using yeast, mammalian and mouse model systems.  We are currently focusing our efforts in dissecting mechanisms of adaptation in response to harsh environmental or genetic perturbations and the role of cellular stresses in promoting genome instability. This research programme has important implications for our understanding of the design principles of cellular systems as well as for both medical and synthetic biology applications.
