Monika Cichmińska

has been teaching English for 20 years. After graduating from the University of Łódź, where she specialised in linguistics, she co-founded Progres, a private language school in Łódź, where she taught at all levels and was the Director of Studies. In 1999 she finished her doctorate in linguistics and moved to Olsztyn, where she works at the University of Warmia and Mazury. She also works for English Perfect, a private language school in Olsztyn, where she is the  Director of Studies. Apart from that, she likes to work as a teacher trainer for various institutions. She is also an oral examiner for UCLES (FCE, CAE and CPE).
She enjoys working with people, and likes to combine theory (linguistics, psychology and neuroscience) with practice (teaching English on all levels). She is particularly interested in teaching, or rather uncovering grammar, motivation (of both students and teachers), affective factors in learning, and most of all, what happens in the brain when we learn something new.
In her free time she likes to learn new things, go to the cinema, listen to music, and go for long walks with her son. Her personal idols are Pat Metheny, Cassandra Wilson, Ken Wilber and Gregory House.
