Akira Kawaguchi


Akira Kawaguchi (川口明 in Japanese notation) is a full professor, currently serving as Chair of Computer Science and Co-Chair of Computer Engineering Programs. He received his B.E. and M.E. degrees in Administration Engineering from Keio University in the city of Yokohama, Japan, and M.S., M.Phil, and Ph.D. degrees in Computer Science from Columbia University in the city of New York. He worked for seven years at Mitsubishi Heavy Industries, Ltd as an assistant manager in its Tokyo Head Office, acquired Mitsubishi's two-year fellowship for his graduate studies in the U.S., and left Japan with a one-way ticket to New York. He devoted himself to the forefront of database research, which resulted in his lifelong collaborations with researchers in Columbia, Bell Labs, AT&T Labs, IBM Research, and various Japanese industries. After finishing his dissertation in 1997, he joined the Department of Computer Science at the City College of New York and the CUNY Graduate Center, where he became one of a small and invaluable class of scholars with the ability to build an intellectual bridge between the U.S. and Far East countries.

Professor Kawaguchi's primary research interests center around areas of database and transaction processing systems. He will take students with outstanding math backgrounds -- wishing to develop next-generation software systems together.

Research Interests

Publications listed at Google Scholar Entry

Conducting research in the area of software systems, with focus on database and transaction processing. Recent achievements are roughly grouped into the categories below, all of which involve demonstrative implementations:

  • Highly Distributed Data Processing on Programmable Overlay Networks: distributed data processing requires a combination of computing platforms providing effective data networking as well as architectural extension of cloud computing with more flexibility than that found in conventional networks by allowing the integration of a massive number of components and services. This effort focuses on the analysis of performance gain in dynamic systems, i.e., highly distributed data and service environments built and deployed on programmable overlay networks. Such a distributed and dynamic modeling is an enabler of more advanced solutions that need lightning-fast responses from data processing engines, e.g., machine learning gives us the ability to extend the reach of analytics to encompass not just data but also images, video, facial expressions, human speech and other sources of insight.
  • Engineered Network Paradigm: investigating areas in the context of engineered networks: 1) alignment of logical networks with physical substrates, 2) network vulnerability, and 3) security. The alignment issue is quite challenging as a theoretical question, so we would concentrate on developing acceptable heuristic solutions such as we have proposed in the hypercube case. Network vulnerability would be approached from the perspective of potential attacks that threaten to break a network into several isolated components – we proposes to attack this problem by elaborating a sound and practical definition of vulnerability introduced in our previous work. The security part of the research would focus on variations of network coding that can take advantage of known independent paths in an engineered network. In principle this offers an alternative to encryption that has the advantage of using far less bandwidth.
  • Distributed Query Optimization: examines the problem of join query optimization in a Dynamic Distributed Federated Database and the role that network topology, specifically an engineered hypercube, could play in the cost estimation. Considering that many nodes in this environment may rely on batteries and wireless radios, we would like to minimize network information transfer to maximize network availability and lifetime. While in any topology it may be assumed a querying node can estimate distance to data sources, in an unknown topology, the querying node has no knowledge of intersite distances. In a hypercube, these distances can be easily calculated at the querying node based on the sites' labels. What is more, query optimization in the past has not fully taken account of the topology of networks as a cost factor in executing joins. We are conducting a quantitative evaluation of distributed query performance that takes account of network topology.
  • Data-warehouse and Decision Support: emphases on data quality investigation and enhancement of decision support. Involved in interdisciplinary research work with civil engineering, biomedical engineering, and biology for the development of specialized data-warehouses such as deterioration rate analysis for NYS bridge data elements, asset inventory and internal inspection ratings for NYC water pipe maintenance, wireless biometric data collection capabilities for diabetes care, and easy retrieval of genes whose expression is altered by parasitoid infections. The most recent work spans into mathematical characterizations of database errors and the effect of error propagation in decision support as well as integration of operations research tools into decision making. A new subject in more traditional side, entitled distributed query processing on hypercube network, is also in progress.
