Postdoctoral Research Associate in nutrition, mathematics, engineering,
or computer science. This is a 2 (possibly 3) year appointment - it is a
noncareer (not permanent) position.

Grand Forks, North Dakota 58202


The incumbent will develop new procedures involving novel mathematical
or computer approaches such as chaos, catastrophe, fractals, fuzzy logic,
neural networks, and other cognitive methods that could be used for
deriving Recommended Daily Allowances (RDAs). An underlying concern with
derivation of the RDAs, is that an element of judgment is required when
deciding which data to use and how the data should be used. This project
would determine methods, which if were employed, would make the RDA process
more objective. The incumbent would use existing data to derive a
systematic approach for derivation of RDAs for mineral elements. Work
could be theoretical, but the goal is to establish a mechanism and working
model to make the RDAs more objective and more informative.


Knowledge of mathematics in one or more of the following areas:
chaos, catastrophe, fractals, fuzzy logic, neural nets, or other cognitive
methods. Experience in computer programming. Knowledge of nutrition is
desirable but not necessary.


Recommended Daily Allowances (RDAs) are defined as the intakes of essential
nutrients that, on the basis of scientific knowledge, are judged by the
Food and Nutrition Board to be adequate to meet the known nutrient needs of
practically all healthy persons. RDAs are used to plan and procure food
supplies for population subgroups; to interpret food consumption records of
individuals and populations; to establish standards for food assistant
programs; to evaluate the adequacy of food supplies in meeting nutritional
needs; to design nutrition education programs; to develop new products in
industry; and to establish guidelines for nutrition labeling of foods.

An underlying concern with derivation of the RDAs, is that an element
of judgment is required when deciding which data to use and how the data
should be used. This project would determine methods to make the RDA
process more objective. The incumbent would use existing data and novel
mathematical/computer approaches such as chaos, catastrophe, fractals,
fuzzy logic, neural networks, or other cognitive methods to derive RDAs for
mineral elements.


The Grand Forks Human Nutrition Center is one of five human nutrition
research centers operated by the ARS. The mission of the Center is to
determine nutrient needs for humans and to provide information concerning
healthy food choices and a healthful food supply. Emphasis is on
determining mineral requirements that prevent disease and promote health
and optimal function throughout life. The 80,000 square foot facility
contains a laboratory for each of 13 senior scientists, a 14-bed metabolic
ward for long-term, live-in human volunteer studies, and a separate area
for community-based human studies. The Center is located near the campus
of the University of North Dakota where access to a Cray J-90 computer is
available, if needed.

The Postdoctoral Research Position (also referred to as Associate or
Associateship) offered through the Agricultural Research Service (ARS) is a
noncareer appointment which will last two years (there are situations,
however, in which the appointment can be extended). Applicants must have
completed requirements for the Ph.D. degree prior to entrance on duty
(starting dates are flexible). Preference is to hire persons with no more
than 4 years postdoctoral experience. However, well-qualified scientists
more than 4 years beyond the Ph.D. degree should not hesitate to apply.
Eligible applicants will receive consideration without regard to race,
color, religion, sex, age, nondisqualifying physical handicap, or national

Associates are appointed at no less than the first step of grades GS-11 or

appointed initially for longed than a year are eligible for health and life
insurance benefits. Job-related death or injury is covered by the Federal
Employees Compensation Act. Any moving allowances will be discussed.

Associates devote full-time effort to research and advanced training. No
additional monetary aid may be accepted from another appointment,
fellowship, scholarship, grant or similar personal funding during the
period of the Associateship. The laboratory will provide the necessary
support service, supervisory, facilities, and equipment for the research.
Publication of research results obtained during the period of the
Associateship is strongly encouraged.

There is no specific closing date for this position. If interested, please
e-mail, fax, or mail me your resume/CV. If at all possible, include your
e-mail address for further correspondence.
