Areas of expertise

natural language processing
machine learning
scientific text mining


I am a researcher in the TurkuNLP group ( and Associate Professor at the Department of Computing, University of Turku. My research focuses on machine learning for natural language processing, with particular application domains including scientific text mining and Finnish language technology.

After defending my PhD thesis in computer science at the University of Turku, I held researcher positions at the University of Tokyo, University of Manchester and University of Cambridge before returning to the University of Turku as an Associate Professor in 2019.


My current teaching focuses on the natural language processing study module shared between the departments of Languages and Computing, with courses ranging from introductory to a course on deep learning for natural language processing.


The primary focus of my research is on natural language processing using machine learning approaches, with recent emphasis on deep learning methods. I have been working on scientific text mining as an application area for nearly 20 years, with specific focus on the English biomedical literature, and have in recent years also addressed a variety of tasks in the processing of Finnish text as well as multi- and cross-lingual applications. My work covers the full range of natural language processing development from initial task design to the development of practical applications and organizing community challenges, including also running manual annotation efforts and developing annotation tools and machine learning methods for various natural language processing tasks.
