Dear colleagues,

It is with a heavy heart and with great sorrow that I share with you the 
devastating news that our esteemed colleague Freek Ariese passed away 
last Friday, while travelling back from Germany with his family.

Freek's unexpected and untimely passing away is a terrible blow for the 
department. In addition to a successful scientist and an impactful and 
appreciated teacher, Freek was a wonderful person and colleague, always 
kind and willing to help everyone. Our department will miss him very sorely.

On behalf of the department, we send our warmest condoleances to his 
wife Anna, all of Freek's family, his colleagues of the Biophotonics and 
Medical Imaging section, and all other close collaborators and 
colleagues of Freek within the department and the Faculty of Science.

Freek's passing away represents a huge loss for many of us, both 
personally and professionally. A lot of strength to everyone. Do not 
hesitate to reach out to the MT if we can be of any kind of assistance 
in these trying circumstances.

As soon as we receive more information, we will share it with the 
department.

Best wishes,

Juan (on behalf of the MT and of the BPMI section)
