Personal profile

Research interests

My research interests have grown around natural language processing and they deal with long-term computational and infrastructure challenges arising in data production and modeling.

I. Computational Aspects of Linguistic Form and Meaning 

  • Functional Linguistics / Graph-Based Representations of Meaning
  • Surface Constraints and Sub-regular Languages
  • Sequence Labeling Parsing / Sequential Graph Representations
  • Code-Theoretic Analysis of Transition-Based Parsing
  • Explainability of AI and Weighted Automata

II. Finite Representations of Infinite Sequence Relations 

  • Transducers
  • Alignment Models
  • Computational Phonology and Tonology
  • Semantics of Rewriting Systems

III. Research Infrastructures

  • Visting Center Facilities
  • Data Resources
  • Sensors
  • Living Labs
  • GPU servers

In NLP, I am currently 

My main current academic job is in the Faculty of Agriculture and Forestry where I am

  • a research coordinator at Viikki 
  • a Developer of Sensor and Data Acquisition technologies for the Living Lab infrastructure  at Hyytiälä
  • a member of the Construction Committee of new buildings to Hyytiälä  

Description of research and teaching

My research in Language Technology is on hold, due to my career path that has led me outside the Faculty of Arts. As my hobby, I aim to continue my fundamental research on structure representations within the context of Computer Science.  I am currently working on data infrastructures in the Faculty of Agriculture and Forestry and learning social working skills as a research coordinator responsible for the development of longitudinal research facilities.

I have taught in different faculties, international contexts, and at my alma mater. Examples:

In 2012-2013, I served as the Head of Subject, in Language Technology teaching several other courses such as:

I am a Qualified Teacher and a member of the Teaching and Researching personnel of the University of Helsinki, but I am not teaching currently due to my current assignment as a Research Coordinator in the Faculty of Agriculture and Forestry.
