Biography
Katerina Politi studied Biology at the University of Pavia in Italy. She then moved to New York, where she obtained her PhD in Genetics and Development working with Argiris Efstratiadis at Columbia University. Following graduate school, she joined Harold Varmus's lab at Memorial Sloan-Kettering Cancer Center and began her work on the molecular basis of lung cancer. She continues this work at Yale as a Professor in the Department of Pathology and Yale Cancer Center.
