Research
I'm working on the Intelligent Computer Assisted Language Learning platform Lärka.
My work focuses on modeling and predicting lexical complexity of words and improving the language learning experience by personalizing the experience for the user using both individual and group modeling.
I'm also interested in developing more open ended exercises.
