  • Profile

    Website Abbe Mowshowitz has been professor of computer science at the City College of New York and member of the doctoral faculty at the Graduate Center of the City University of New York since 1984. In this period he has also held academic appointments at the University of Amsterdam, Erasmus University Rotterdam, and the Rotterdam School of Management. Earlier he held academic appointments at Rensselaer Polytechnic Institute, the University of British Columbia, the University of Toronto, and the University of Michigan. Mowshowitz began his research career in information theory and discrete mathematics, but shifted to organizational and social implications of computers some decades ago. He was awarded the 1990 Tinbergen Professorship at Erasmus University-Rotterdam in partial recognition of his work on computers and society. He has authored several books and reports (including THE CONQUEST OF WILL: INFORMATION PROCESSING IN HUMAN AFFAIRS, 1976), and many articles on the social implications of computing. In recent years, his research has centered on virtual organization (an idea he conceived in the late 1970s). A book on this subject (VIRTUAL ORGANIZATION: TOWARD A THEORY OF SOCIETAL TRANSFORMATION STIMULATED BY INFORMATION TECHNOLOGY) was published in 2002. In addition to teaching and research, Mowshowitz has acted as consultant on the uses and impacts of information technology (especially computer networks) to a wide range of public and private organizations in North America and Europe.

  • Research Interests

    My current research interests lie in two areas: 1) organizational and managerial issues in computing, and 2) network science. A central focus in the first area is virtual organization, especially the “switching model” and its relationship to the problem of dynamic resource allocation. This research is an extension of work reported in my book Virtual Organization. In the second area I am studying network growth models, network vulnerability, embedding virtual networks in physical substrates, and the identification of ‘communities of interest’ in networks. Much of this research grew out of my participation in the International Technology Alliance funded by the U.S. Army Research Lab and the U.K. Ministry of Defense.

    My colleague Professor Kawaguchi and I (having worked together in the ITA project) are focusing on further exploitation of engineered networks. By guiding the growth of systems such as Dynamic Distributed Federated Databases (DDFD) into well-defined graph structures (e.g., hypercubes, toroidal graphs, Kautz graphs, etc.), it is possible to exploit properties of the known graphs to improve the efficiency and effectiveness of communication and message passing as well as to make distributed systems more robust and secure.

    We have demonstrated the utility of this approach in our earlier work in the International Technology Alliance (ITA) project by showing how an engineered hypercube structure can be used to improve the efficiency of the query optimization process in a distributed database environment. We have verified this in a special case of a DDFD, namely the Gaian Database developed by IBM-UK.

    Building on this ITA work, we propose to investigate further three related 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 ITA 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.
