Rob successfully defended his doctoral thesis in April, 2021, in the videoconference format that became the norm during the Covid-19 pandemic! He was interested in network architecture in general, and worked on both the ChoiceNet project, and the JUNO Optical ChoiceNet project, and designed service representation, negotiation, purchasing, and provisioning methods in those frameworks. The bulk of this thesis research went toward a comprehensive study of the effects of interaction of customer and provider strategies in hybrid optical packet-circuit networks, and designing strategies that result in collaborative optimization of network performance, for a win-win scenario. He published over a dozen papers during his PhD. For the last few years of his PhD, he has been also working full time at NetApp, where he continued immediately following his doctoral defense.
