I'm currently living in Helsinki, Finland, where I am employed as a postdoctoral researcher at the University of Helsinki's Department of Digital Humanities.

Before, I did my PhD in Computer Science at the University of Leipzig, Germany and was member of the Natural Language Processing Group there. In my dissertation, I explore a novel method of unsupervised learning of language morphology based on a little-known linguistic theory, that is very different from the "mainstream" views on morphology.

My favourite part of the work in academia is teaching. I have taught courses about NLP and text mining, as well as Algorithms and Data Structures.

I was born and grew up in the lovely Wrocław in southwestern Poland.

You may be confused about whether my first name is Maciej or Maciek. The fact that J and K are next to each other on the keyboard does not make it easier. Here's the thing: Maciej is the formal and official variant of the name, whereas Maciek is more informal (more exactly, a diminutive). Sort of like William and Bill. The ci digraph is pronounced /t͡ɕ/, similarly to ch in English cheese.

One of my hobbies is linguistics and learning languages. Besides my native Polish, I am fluent in English and German, have some command of Finnish, Swedish, Dutch and Russian and have unsuccessfully attempted to learn Lithuanian multiple times. Feel free to email me in any of those languages (including Lithuanian, but it might take longer for me to answer).

I play electric bass and used to play it for Linie 7ieben. You can see music videos featuring me here and here (I used to look quite differently back then). I also play on their studio album "Lauter".

I am a practicing Christian.
