POSTDOCTORAL POSITION:

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.

LOCATION:

U.S. Department of Agriculture
Agricultural Research Service
Grand Forks Human Nutrition Research Center
Grand Forks, North Dakota 58202

DESCRIPTION OF DUTIES:

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.

SPECIAL REQUIREMENTS:

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.

PROJECT FOCUS:

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.

RESEARCH ENVIRONMENT:

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.
