Nearly 40 years of science
After a distinguished career spanning over four decades, Christof is retiring from his role at the Laboratory for Neutron Scattering & Imaging (LNS). His contributions as a scientist, instrument builder, mentor, and colleague have left a meaningful mark on our community, and we take this moment to express our gratitude and best wishes.
A career of contribution
Christof’s journey in physics began with his studies at the University of Konstanz, where he earned his Master’s (1986) and PhD (1990). His career took him from Konstanz to Vancouver, and eventually to LNS, where he became known for his technical expertise, collaborative spirit, and dedication to advancing neutron scattering and supporting users.
He played a key role in developing instruments like LEM and CAMEA at PSI, as well as BIFROST at ESS, which have enabled important progress in the field. His work also extended to building scientific networks through initiatives such as Danscatt, MAMASELF, LENS, helping to connect researchers and foster collaboration across institutions. Christof has also contributed to the general success of PSI as a member of the research commission FOKO.
Research and mentorship
With over 220 publications, including notable papers in Nature, Physical Review Letters, and Physical Review B, Christof’s research has advanced our understanding of solid state dynamics. As a mentor, he supported 8 postdocs, 12 PhD students, and 15 diploma students, sharing his knowledge and encouraging their growth.
Christof’s presence in the lab was defined by his enthusiasm for science, his supportive nature, and his ability to make complex ideas feel accessible. Whether through his famous "Wunderbar!", his reminder that "there is no ‘should’ in physics", or his descriptions of experiments as "ballets of neutron scattering", he brought a unique perspective and warmth to his work.
His colleagues will remember him not only for his scientific achievements but also for his empathy, encouragement, and the many discussions that made working with him both productive and enjoyable.
As Christof moves on to this new chapter, we thank him for his dedication, friendship, and the many ways he has enriched our scientific community. We wish him all the best in retirement and look forward to seeing the impact of his work continue.
Thank you, Christof, for everything. We are glad to continue seeing you at PSI and around!
