His dissertation research (done at Princeton University) is in the area of software implementations of distributed shared memory (DSM). While conducting the research, Liviu developed new techniques to enhance the performance of shared virtual memory (SVM). The main contributions of his thesis include the class of home-based release con sistency protocols for SVM, a new approach to building SVM by using automatic update hardware support, and a consistency model called Scope Consistency. Also, while he was doing his graduate work at Princeton, Liviu worked with a scientist from Matsushita Information Technology Laboratory and together they performed the first study to address the effects of mobility on reliable transport protocols.
Upon his arrival at Rutgers, he began to establish a laboratory irt distributed systems. During the Fail he taught a graduate seminar in research topics in operating systems.
