Lisa Randall is an American theoretical physicist known for her work in particle physics and cosmology. She is a professor at Harvard University and has made significant contributions to the understanding of extra dimensions, fundamental forces, and the nature of dark matter. Randall is particularly well-known for her work on models involving extra dimensions of space, such as the Randall-Sundrum models, which aim to explain the hierarchy problem in physics and the behavior of gravity at different scales.

Lisa Randall co-developed a geometric approach to the hierarchy problem with Raman Sundrum. Their Randall–Sundrum model uses a slice of five-dimensional Anti-de Sitter spacetime; its varying spacetime metric converts a fundamental large scale into a much smaller scale on the brane containing Standard Model fields. The mechanism relies on warping rather than an enormous compactification volume. It illustrates how assumptions about inaccessible spatial geometry can imply measurable particle excitations.[ref]
