An important objective of the program is to disseminate leading-edge research results that will benefit the scientific community, industry, policy-makers and the general public.  MAGNET encourages trainees to present the results of their work at international conferences and to publish their research in respected journals.  The following refereed articles have been published by MAGNET trainees (underlined).
