Annual Report 2015 cover

Annual Report IEMR 2015

Several new postdocs and PhD students were hired in 2015. Altogether we had the pleasure of welcoming 11 new people to IEMR. The core staff now counts 72 people at the institute and about 15 people that are employed other places do their entire project or parts of it at IEMR.

Six theses were defended in 2015, and altogether 35 articles were published, many of them in collaboration with colleagues abroad. One paper was selected as one of the six best publications from the hospital in the spring 2015. The institute is host to three regional core facilities.
