An experimental researcher whose joint study tracked the <Brownian motion> of ellipsoidal particles. Their nonspherical shape makes motion along the long axis differ from motion across it. Following both position and orientation with video microscopy reveals how particle geometry changes random motion even in an otherwise uniform liquid.<Brownian Motion of an Ellipsoid by Yilong Han and others>[pp. 626–627, Fig. 1: ellipsoid tracking and body-frame displacements]{ref}
