I am shocked by the news that our PhD student Jan Feldhoff died unexpectedly
in a tragic accident in the first days of March, 2014. We have worked together to develop
the intersystem and joint recurrence network approaches for investigating coupling
directions from measured data. Jan was very open, cheerful, and inquisitive.
I will miss a young and promising scientist. I still cannot believe that this
unbelievable tragedy has happened and that we will not have any opportunity anymore
to meet, to laugh, and to discuss together.
