Edward Cheng

PhD in Computer Science and Information Systems

To satisfy my hunger for knowledge and to sharpen my skills in research and publications.

Dr Edward C. Cheng, is a technology enthusiast and software engineer. He is the lead inventor of the Log-Structured Merge Tree (LSM Tree) algorithm, which is adopted by all major Big Data Management Systems in the world today as the data management algorithm for low-latency, high-throughput, and high velocity datasets. These include Google Big Table, Facebook, Twitter, Microsoft, Oracle, Hadoop, Casandra, MongoDB, RocksDB and others. He was awarded a PhD from Birkbeck, University of London in 2004. Edward was previously the founder and CTO of EGI Technologies, Inc., a Big Data and AI company based in San Mateo, California. He is currently a Senior Director of cloud technology at Oracle Corporation, having also worked in R&D at DEC and HP.

His main reason for undertaking a PhD was "to satisfy my hunger for knowledge and to sharpen my skills in research and publications". He chose the School of Computer Science and Information Systems at Birkbeck because it provided him with "a world renowned and flexible research environment" and allowed him to "grow in my focused area of study - collaborative computing technologies - without sacrificing my on-going career development".

Edward said that although the true benefit of his PhD was in the development of expertise, knowledge and skills throughout the years of research and study, the qualification has enabled him to converse and interact globally with other researchers of similar calibre. It also allows him to quickly engage with clients and establish points of reference and expectations when providing professional consulting services to enterprises. This is essential at EGI, where Edward manages the company to design, develop and deliver global collaborative management solutions to Fortune 500 companies. Talking about the other ways in which his time at Birkbeck has helped him, he commented "it has given me exposure to the European community and I have gained, in my PhD supervisor, a life long advisor and friend."
