Colleagues describe him as "I was working with John-Erik in the Data Acquisition Group of the ATLAS experiment at CERN for two years. I consider him as the excellent software designer with deep understanding of OO programming and extensive experience with C++, Java and Python. He used his scientific competence to provide very effective and unique solutions to our specific problems and demonstrated strong interest to ‘hard-to-solve’ challenges. John is good team player with the sense for responsibility and he is very patient. He was behaving as a spontaneous consultant to many young (and senior too) colleagues. It was pleasure to work with somebody always open to knowledge sharing and constructive discussion. I would like also to stress his strong teaching capability. With no doubt any professional team will benefit from his experiences."
