The staff and students wish Professor Szyszkowski all the best in his retirement. Professor Szyszkowski joined the staff of the department in 1991. During his distinguished career he taught and supervised extensively. Professor Szyszkowski's dry sense of humour and enthusiasm for "advanced" mathematics kept the students engaged and interested during his classes and entertained all during staff meetings. Professor Szyszkowski made an immense contribution within the department and he will be missed.

Irek, thank you.
