Slight correction: his sci-tech award was for MIS and "efficient Monte Carlo path tracing for image synthesis", which have only been in PRMan for the last two releases (PRMan 18 added geo area lights with MIS evaluation, and 19 added pure path-tracing), so his award wasn't for his work at Pixar really as that happened 12+ years before the techniques the award was for made it into PRMan.
