THE NATIONAL ACADEMIES
Advisers to the Nation on Stienre, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distin-
guished scholars engaged in scientific and engineering research, dedicated to the furtherance of
science and technology and to their use for the general welfare. Upon the authority of the
charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to
advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is
president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the
National Academy of Sciences, as a parallel organization of outstanding engineers. It is
autonomous in its administration and in the selection of its members, sharing with the National
Academy of Sciences the responsibility for advising the federal government. The National
Academy of Engineering also sponsors engineering programs aimed at meeting national needs,
encourages education and research, and recognizes the superior achievements of engineers.
Dr. Wm. A. Wulf is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to
secure the services of eminent members of appropriate professions in the examination of policy
matters pertaining to the health of the public. The Institute acts under the responsibility given
to the National Academy of Sciences by its congressional charter to be an adviser to the federal
government and, upon its own initiative, to identify issues of medical care, research, and
education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916
to associate the broad community of science and technology with the Academy's purposes of
furthering knowledge and advising the federal government. Functioning in accordance with
general policies determined by the Academy, the Council has become the principal operating
agency of both the National Academy of Sciences and the National Academy of Engineering in
providing services to the government, the public, and the scientific and engineering commu-
nities. The Council is administered jointly by both Academies and the Institute of Medicine.
Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the
National Research Council.

Preface
n 1993, the National Research Council's Board on Biology established a
series of workshops on biotechnology. The purpose of the discussions is
to foster open communication among scientists, administrators, policy-
makers, and others engaged in biotechnology research, development, and
commercialization. The neutral setting offered by the National Research
Council is intended to promote mutual understanding among government,
industry, and academe and to help develop imaginative approaches to prob-
lem solving. However, the objective is to illuminate issues, not to resolve
them. Unlike study committees of the National Research Council, work-
shops cannot provide advice or recommendations to any government agency
or other organization. Similarly, summaries of workshops do not reach
conclusions or present recommendations but instead reflect the variety of
opinions expressed by the participants. The comments in this report reflect
the views of the workshop participants as indicated in the text.
The first workshop, held in 1996, focused on intellectual property rights
issues related to plant biotechnology. Other workshops have focused on
broad issues related to developing an agricultural genome project, privacy
in biomedical and clinical research, and the field of bioinformatics.
On August 19, 2003, the Board on Life Sciences held the workshop on
"Progress and Promise in Systems Microbiology." The systems approach
attempts to use comparative, high-throughput assays and mathematical or
computational models to generate a picture of system-wide activity that can
yield insight into processes operating within the system. The workshop
brought together scientists in academe, government, and other institutions

PREFACE
with representatives of the US Department of Energy, the National Science
Foundation, and the National Academies. The focus of the workshop was
on communication among scientists in different disciplines pertinent to the
application of systems biology to microbial ecology, with a goal of facilitat-
ing transition among science and application and information dissemina-
tion. The training of next-generation scientists with an emphasis on the
interface of biology and computational biology was also stressed during the
workshop.
Several themes emerged during the discussions, which began with con-
crete case studies of particular microbial systems and proceeded to research
and educational needs to support further development of the field. Micro-
bial ecosystems offer unique opportunities for practical bioengineering
applications and attractive mode! systems for basic biological research. Sub-
stantial basic research is needed to develop the theory, software tools, and
experimental methods required to support systems microbiology, but the
case studies showed that progress has already been made by coupling math-
ematical modeling with experimentation. There was wide agreement that
tight interactions of too! development with practical applications is needed,
not only to keep too! development relevant and motivated but also because
the current challenges for microbiologists in dealing with the enormous
complexity of their systems and data can benefit from incremental progress
in modeling, simulation, and analysis tools.
