Lisa Randall (born 18 June, 1962) is an American theoretical physicist and a leading expert on particle physics and cosmology. She works on several of the competing models of string theory in the quest to explain the fabric of the universe, and was the first tenured woman in the Princeton University physics department and the first tenured female theoretical physicist at MIT and Harvard University. Her work has attracted enormous interest. In common with other researchers in this field, however, none of her theoretical work has yet been confirmed by experiment.
