I am a big fan of all things open, including open data, open source, and open science. Recently I’ve also been active in the MyData community. Below I have listed some open stuff that I’ve been involved in.
Open data science at Reaktor
- GIST cancer risk calculator: web service, blog post
- Kannattaakokauppa.fi (apartment price modeling and visualisation): web service, blog post, interviews in Finnish: HS, Iltasanomat
Open source projects and tools for open data
- helsinki - Helsinki open data R tools
- gisfin - Finland GIS R tools
- sorvi - Finnish open government data R tools
Since 2011 I have been developing open source tools for processing, analyzing and visualizing open data with a few Finnish friends in the Louhos project. It all started with our sorvi R package winning the Apps4Finland 2011 data opening category. Since then, our blog (in Finnish; migrated from Wordpress in June 2014) has received more than 30000 views and we’ve won also other prices in Apps4Finland. Currently we are developing the rOpenGov R ecosystem for open goverment data. We already have a lot of packages involved all around Europe and the US, and even more are being developed.

Research on machine learning and bioinformatics
I finished my PhD studies in Aalto University in 2014. In my thesis I developed machine learning methods for molecular biology and medicine applications.
