On learning molecular biology in François Gros' lab in the late 1970s and early 1980s.

Although reflection is obviously crucial in molecular biology, experimentation is nonetheless the basis of most major advances. I was lucky to begin my research career at a particularly interesting time, and privileged to have spent a number of years in Francois Gros' laboratory at the Institut Pasteur. His influence, and that of his lab, were crucial in shaping my early career.
