Associate Animal Nutrition Officer

IAEA Careers / Argonne National Laboratory

About the organization

The International Atomic Energy Agency (IAEA) in Vienna, Austria is the world’s center for cooperation in the nuclear field committed to promoting safe, secure and peaceful uses of nuclear technology. The IAEA offers opportunities to engage current, meaningful issues of global peace, security and development while working in a multicultural environment.

Working at the IAEA is a rewarding experience and provides an opportunity to contribute to the promotion of peaceful uses of nuclear technology and to sustainable development. As the largest contributor to IAEA programs, the U.S. is committed to encouraging well-qualified Americans to apply for professional posts at the IAEA.

The IAEA employs professionals from a variety of scientific and policy backgrounds. The IAEA offers different types of employment opportunities: for professional and general service posts; consultants and experts; junior staff, through internships; and the Junior Professional Officer program.


The Associate Animal Nutrition Officer will be co-responsible, under the supervision and guidance of the Head of APH and the technical officer(s) responsible for the activities and projects in animal
production, for a study aimed at developing a practical method to predict pasture intake of ruminants grazing heterogeneous pastures and rangeland using stable isotopes to provide tools for better grassland management that enhance animal productivity and reduces impact on environment due to overgrazing, and to allow the design of effective feed supplementation strategies at farm level to optimize animal production. The methods will include analysis of concentrations and stable carbon isotope composition of n-alkanes in the plant and faecal samples to predict dry matter (DM) intake and its plant proportions and development of the near infrared reflectance spectroscopy (NIRS) predictive equations of DM intake and the plant profile of that intake. The equations are expected to facilitate the design of diets and supplements required to cover the nutritional needs of animals to optimize their productivity.

As a member of the Animal Production and Health group the Associate Animal Nutrition Officer will be based at the Vienna International Centre and will maintain regular contact with the staff of APH. S/he will be based on an established work plan, technically assisting the team on the analysis of nalkanes in the plant and faecal samples and their compound specific.


University degree in biological, agricultural, veterinary or animal sciences. Post-graduate
training up to PhD level or equivalent in a subject related to animal nutrition, feed resources,
pasture management and or isotope technologies an asset.
• Minimum two years of experience and working knowledge on the analysis of stable isotope,
alkanes, wet chemistry of feeds and forages, NIRS with sound knowledge in computer
applications to compute predictive equations.
• Fluency in both written and spoken English is essential. Knowledge of other official IAEA
languages (i.e. Arabic, Chinese, French, Russian or Spanish) an advantage.
• Competence in computer applications including word processing, spreadsheets, databases,
presentation graphics and statistical packages.
