An experimental condensed matter physicist who, with T. G. Mason, developed optical microrheology of complex fluids. Dynamic light scattering measures the random displacement of probe particles; a generalized Langevin equation relates those fluctuations to the fluid's storage modulus and loss modulus. Comparing the result with mechanical measurements showed that microscopic motion could probe bulk viscoelasticity over a broad frequency range.[ref]
Optical Measurements of Frequency-Dependent Linear Viscoelastic Moduli of Complex Fluids by T. G. Mason and D. A. Weitz Created 2026-10-20 Updated 2026-11-05
By T. G. Mason and D. A. Weitz. Physical Review Letters 74, 1250–1253; published 13 February 1995. DOI: doi.org/10.1103/PhysRevLett.74.1250. The publisher's abstract reports dynamic light scattering to infer linear viscoelastic moduli from probe displacements and comparison with mechanical measurements. Publisher record and abstract. No uninspected apparatus parameters are inferred from that abstract.
