David D. Lewis, Ph.D. 858 W. Armitage Ave., #296 Chicago, IL 60614 U.S.A. phone: 773-975-0304 fax: 773-289-0507 Services: I work with clients to make the most effective use possible of textual data. Applications I have worked on include search engines, text categorization, filtering of email and web pages, mining of customer data, and a variety of others. My clients have included both vendors and users of text processing software, and my work with them has included mining data sets, analyzing manual and automated text processing procedures, designing algorithms and system architectures, performing competitive and strategic analysis, training, and ongoing advisory relationships. Contact me to see how we can work together.

Bernardo Huberman is a Senior HP Fellow and Director of the Social Computing Lab at Hewlett-Packard Laboratories. He received his Ph.D. in Physics from the University of Pennsylvania, and is currently a Consulting Professor in the Department of Applied Physics at Stanford University. He originally worked in condensed matter physics, ranging from superionic conductors to two-dimensional superfluids, and made contributions to the theory of critical phenomena in low dimensional systems. He was one of the discoverers of chaos in a number of physical systems, and also established a number of universal properties in nonlinear dynamical systems. His research into the dynamics of complex structures led to his discovery of ultradiffusion in hierarchical systems.
