Image from James Grieve's thesis. Thermal ellipsoids representing the two-sigma tip position for an optically trapped composite microtool (experimental data). For certain trapping configurations it is possible to rotate the ellipsoid with respect to the optical axis - something which is impossible with traditional microsphere probes.
Both Andrea Gazze and James Grieve produced work that their examiners considered to show outstanding excellence in a doctoral thesis. We congratulate both of them and wish them every success for the future.
