The JRC employs some 2750 staff and has an active policy of attracting bright and able scientists. Staffs come from throughout the EU, and from the applicant countries, bringing their skills and talents to help resolve current scientific issues. Major advantages are offered by the scientific and cultural diversity in the JRC's multidisciplinary Institutes and cross-Institute scientific collaboration on focused actions. There are various opportunities to work and train with the JRC, which range from permanent appointments to fellowships for young researchers and senior scientists (see the jobs section). There are also possibilities for short and long-term collaboration with the JRC.
