About Me

Linguist, Lecturer, Conference Interpreter

My passion for languages goes back to my primary school days. On the one hand, undoubtedly thanks to my grandparents, who were fluent in several languages, I became increasingly sensitive to the different ways in which human thought can be expressed through language. On the other, I owe a great deal to my language and literature teachers, who played a major role in my intellectual development, opening up ever more fascinating paths and perspectives before me.

This is precisely why I decided to continue my education in an experimental language programme, where we explored not only French itself, but also the culture and civilisation of the French-speaking world. This was made possible by a special curriculum, numerous international youth exchanges and the close collaboration of several French teachers teaching us the language of Coco Chanel, Napoleon, Édith Piaf, Zinedine Zidane…  It was then that I first became interested in language teaching, followed by translation and, eventually, conference interpreting.

After four years of study at the Institute of Applied Linguistics at the University of Warsaw, I was awarded a scholarship to study at the Institut Supérieur de Traducteurs et Interprètes in Brussels, where I continued my education and began conducting research into simultaneous interpreting. A study I carried out among professional interpreters formed the basis of my Master’s thesis, supervised by Professor Małgorzata Tryuk, on simultaneous interpreting with relay, a technique widely used in the European institutions and beyond.

It was while working as a conference interpreter that I commenced paying particular attention to political discourse. In time, it became the principal focus of my research and led me to doctoral studies at the University of Warsaw and subsequently, under a cotutelle agreement, at Université Paris Diderot.

Why GJMB?

I would have my flexible tongue
express whatever thought flashes through my mind.
Let my speech be now quick and bright as a thunderbolt,
now sad as a song of the steppe,
now sweet as a nymph’s plaint,
now as fair as angels’ speech. . . .

Juliusz Słowacki, Beniowski, Canto V
(translated by Wincenty Lutosławski, 1911)

These very words inspired the name GJMB, namely Giętki Język Mateusz Białas.

After more than twenty years of working as a teacher, lecturer, linguist and conference interpreter, I decided to bring these different strands of experience together in one place. GJMB was born at the intersection of language research and everyday communication practice. It grew out of my conviction that our knowledge of how language works acquires particular value when we are able to put it to use in real-life communication.

For me, the idea of a “flexible tongue” is not about being impressive for its own sake. It is about choosing our words consciously in regard to the audience, the context and the purpose, while preserving precision, credibility and responsibility for what we say.

GJMB is where language research meets practice.
