studies of cost-performance optimization models of multi-level memory/storage hierarchies. He was also one of the early micro-programmers developing the firmware for a file control unit for an IBM mainframe computer. His article on "CD-ROM" in IEEE Proceedings journal in the 1980s was one of the first articles explaining how CD-ROM worked when CD-ROMs became popular. He was a co-author of the storage technology article in early versions of a computer encyclopedia book published by McGraw-Hill. Cyber security and terrorist detection In recent years, he led a multidisciplinary research team in developing new efficient and effective techniques in identifying terrorists and malicious cyber transactions. At CMU, he is active in the R&D activities of CERT Coordination Center and Software Engineering Institute (SEI). Big data, web services, blockchain and Internet of Things (IoT) He is active in research and lecturing on Big Data and emerging technologies. He was a keynote speaker and a keynote panelist on Big Data at IEEE Conferences. He was the 2014 program chair, the 2015–16 conference chair, and the 2017 honorary chair of the IEEE BigData Congresses. He is the chair of the 2018 IEEE ICWS Conference and the chair of the Blockchain Panel. He is the general chair of the 2019 IEEE Service Congress, Milan, Italy. Publications Peter P.
