An experimental condensed matter physicist who coauthored measurements of anisotropic Brownian motion. An ellipsoidal probe couples translational observations to its changing orientation, so the measured diffusion depends on the time scale and reference frame. Following a single nonspherical particle makes this geometric effect experimentally visible.[ref]
