Sophie Pénisson, Ph.D.

Dr. Sophie Pénisson has a background in mathematics and probability theory. Initially, her research focused on the theoretical aspects of certain mathematical objects (stochastic processes), eventually turning to their use in life science modeling. This led her to discover the impact of their application in cancer research, and she has since chosen to devote herself exclusively to this field. 

Dr. Pénisson holds a French-German joint Ph.D. in Mathematics (French National Institute for Agricultural Research and Potsdam University). After a 10-year academic career at the University of Paris-Est (France), she joined TGen in October 2022 as an applied mathematician. She uses or develops the appropriate mathematical tools to model, understand and analyze the complexity of cancer evolution, in order to improve our early detection and risk prediction capabilities.
