I'm a postdoc researcher and a teacher in the Software Process
Group (SPRG) at CSE Department (SoberIT).
I did my doctoral research on exploratory and experience based
testing that has been my main
research interest. In my current research I am focusing also on the
challenges of creating quality in large-scale agile development context.
I spent 2013 6 months as a visiting researcher at SINTEF, Trondheim, Norway.
I have completed my doctoral dissertation "Empirical Studies on
Exploratory Software Testing" in 2011.
- Intelligent manual testing, i.e. exploratory and experience based
- Quality assurance in time paced, iterative and incremental
- Agile approaches to testing and QA
- Large-scale agile development
Currently I'm involved in two large research projects Finnish national Need 4 Speed and EU funded international U-QASAR project. Earlier I have worked in
research project where we researched software quality practices and quality improvement issues. ESPA builds on the research and
experiences of the previous
A fascinating open source project and a recent start-up is the
Agilefant is a next-generation tool for managing agile software
Agilefant.org had been developed
in our department since 2004.

Hobbies and Interests
I also like sports like cycling, cross-country skiing, in-line
and kayaking - my approach to sports is more enjoying the
nature than striving for competition or results, even though I'm a
little bit obsessed to measuring and logging all activities. I
used to enjoy scuba diving in murky and exciting
Finnish waters as well as in clear-blue waters and breath-taking coral
reefs around the world. You can find some of the best shots of these
underwater experiences on our underwater
photo pages and Flickr.
