Jan,
I don't know what should I say.
You were such a nice guy.
I had many good times with you.
I really miss you.
Sending my deepest sympathy.

I'm sorry to know that you have gone, Jan. You were always so kind and helpful to me. I hope you are at peace now.

Very hard to accept. After many years I still often recall Jan’s time here at Purdue – good science, earnest personal conversations (especially after a couple of drinks). Just recently we discussed a collaborative project – which will not happen...

Thank you Jan!
For being a great friend at Kampsax.
For teaching me the wonder in a Belgian beer on a snow covered bench with good company.
For letting me follow your travels in academia around the world.
For you and Kuriko meeting me in Copenhagen for a wonderful afternoon
RIP
