Is there evidence for supersymmetry? Maria Spiropulu is in search of the elusive partner particles predicted by the theory of supersymmetry. That, in turn, would shed light on mysteries such as dark matter. The renowned Caltech physicist talks about her role in building a detector to fulfill this quest, which cuts across particle physics, astrophysics, and cosmology.

Maria Spiropulu is the Shang-Yi Ch'en Professor of Physics at Caltech.
