My research interests include the application of systems analysis techniques for water resources and environmental problems. I joined the Department of Computer Science at the start of the fall 2001 semester . With Dave Schwartz, I run CS 100 and develop the academic excellence workshops that are associated with that very important course.

I received my A.B. degree summa cum laude in Physics from Harvard University in 1977 and my Ph.D. in Physics from Cornell University in 1981 (Quantum Field Theory, thesis advisor: Kenneth G. Wilson), where I was supported as an NSF graduate fellow and A.D.White fellow. I was in the Harvard Society of Fellows from 1981-84, and an assistant professor in the Harvard University Physics department from 1984-90, where I was supported as an A.P. Sloan Fellow and as a DOE Outstanding Junior Investigator. I was a Technical Staff Member in the Los Alamos National Laboratory Theoretical Division from 1990-2001. I have also held visiting positions at C.E.N. Saclay, France, Princeton University, Stanford Linear Accelerator Center, the Institute for Advanced Studies, Princeton, the Institute for Theoretical Physics at UC Santa Barbara, the Mathematical Science Research Institute at UC Berkeley, and Hebrew University, Jerusalem. In 1991 I inititated the "e-print arXiv" as a new form of communications research infrastructure for physics. I have served on many committees and advisory boards, including most recently an NRC/CODATA committee on "Transborder flow of Scientific Data," an NAS/NRC committee on "Future of Universities," an AAAS study committee on "Transition from Paper," and an NSF committee on "Knowledge Networks and Distributed Intelligence Initiative," and I currently serve on the APS global "Task Force on Electronic Information Systems," on the NIH's "PubMed Central National Advisory Committee," on the Open Archives Initiative Steering Committee (and founder), on the French "Centre pour la Communication Scientifique Directe" technical steering committee (and founder), and on the APS "Publications Oversight Committee." I have also given numerous invited keynote talks and colloquia, including recently at meetings "Future of Mathematical Communication" at the University of Minnesota; "Electronic Publishing in Science" at UNESCO HQ in Paris; "50th Anniversary of the Development of the ENIAC computer" at the University of Pennsylvania; "The impact of electronic publishing on the academic community" in Stockholm, Sweden; "Alternative Models for Scholarly Publishing in Higher Education" at UC Berkeley; Chautauqua meeting of the National Computational Science Alliance at the University of KY, Lexington; joint meeting of the Medical Library Association and the Canadian Health Library Association, Vancouver, BC; "The Impact of Barrier-free Access and New Technologies on Biomedical Publishing" at the New York Academy of Medicine; and "Open Archives European Open day," at Max Planck Library in Berlin. Awards/Honors P.A.M. (Physics Astronomy Math) award from the Special Libraries Association. "Honors work which demonstrably improves the exchange of information in physics, math or astronomy" (1998).

My
core scientific interests lie in machine learning and statistical learning
theory, with its main applications in the fields of text mining and
intelligent information agents. This application domain will be of increasing
importance, since human attention and the speed with which we can process
information are natural bottlenecks that limit our ability to make informed
decisions. While data-base and data-mining techniques can already assist
users when analyzing structured data, the problem of text mining, the
automatic analysis of text-based information, is still largely unsolved.

design by combining knowledge and resources to make products that achieve
some functionality. Despite the fact that design is the basis of engineering,
this process of problem solving by synthesis is not understood well,
and is still taught, to a large extent, as an art. While we have elaborate
computational models for analysis, we still have no computational model
of synthesis. I believe understanding this process holds the key to
future competitiveness, and presents a largely unadressed challenge
across both engineering and computer science.

My
broad research agenda is to build software systems that can serve as
the infrastructure for creating and deploying Internet-based business
applications (also referred to as e-business applications). The need
for building such infrastructure systems arises because currently, in
order to build e-business applications, application developers have
to program against relatively low-level interfaces and write a lot of
special purpose code. This plight of application developers is analogous
to that of programmers in the early days of computing, who had to write
assembly language programs without the aid of software systems such
as compilers and operating systems. My research goal of building software
infrastructure systems for e-business applications is thus motivated
by the need to provide developers with higher levels of abstraction.
