Organizational Setting

The Department of Nuclear Sciences and Applications implements the IAEA's Major Programme 2, "Nuclear Techniques for Development and Environmental Protection". This Major Programme comprises individual programmes on food and agriculture, human health, water resources, environment and radiation technologies. These programmes are supported by laboratories in Seibersdorf, Monaco and Vienna. The Major Programme's objective is to enhance the capacity of Member States to meet basic human needs and to assess and manage the marine and terrestrial environments through the use of nuclear and isotopic techniques in sustainable development programmes.

The Division of Physical and Chemical Sciences is responsible for assisting and advising Member States in research and development for the nuclear sciences, especially the physical and chemical sciences. Specifically, the Division provides support to Member States in the following fields: production of radioisotopes and radiolabelled products for applications in health care and industry; radiation source applications; research reactor utilization; applications of accelerators and nuclear instrumentation; nuclear and atomic data for applications; controlled nuclear fusion and isotope hydrology and geochemistry.

The Isotope Hydrology Section is responsible for planning and implementing the IAEA’s water resources programme. The programme assists Member States in the sustainable management of all aspects of their water resources, but with a particular focus on isotope hydrology. Major activities include internationally coordinated research, global isotope monitoring, capacity building, and technical assistance to Member States to help them with the assessment, development and use of water resources. The Section also operates a well-equipped laboratory for the analysis of stable and radioactive isotopes. The laboratory trains counterparts in using analytical techniques for high-quality measurements of isotopes in water samples.

Main Purpose

As a member of a team led by the Section Head, the Isotope Hydrologist contributes to a results-oriented programmatic response to Member States' priorities in the application of nuclear technologies to meet their development goals related to water resources.


The Isotope Hydrologist is a substantive expert, managing complex projects and a coordinator of project activities with other professionals in the Section, ensuring that tasks are implemented in the most efficient and effective manner in line with quality management standards and the results based approach.

Functions / Key Results Expected

Lead and conduct synthesis, evaluation, and geospatial analysis of isotope distributions in precipitation, surface water and groundwater to develop new or improved methods for understanding climate and hydrological systems.
Contribute to and lead the formulation and implementation of coordinated research projects (CRPs) and other IAEA initiatives to use isotope techniques for water resources assessment and management.
Contribute to and carry out a strategic and technical analysis of current issues in water resources management where isotope techniques can be integrated to provide effective solutions.
Identify and nurture programmatic partnerships with other UN agencies, particularly to develop co-funded projects and for outreach purposes.
Provide technical support and guidance for IAEA technical cooperation projects in the field of isotope hydrology.
Lead and coordinate training of Member State scientists in isotope hydrology. , including the use of laser spectroscopy for isotope measurements in water, air and soil samples.
Plan, organize and participate in seminars, workshops, expert missions and training courses.
