In addition to my personal blog, I’ve been contributing to these other blogs (some pieces published in multiple blogs):
- What did we learn from using Fitbits for a year?
- Using visualizations to communicate data science – Case cancer risk analysis
- More privacy and better personalization – a mission impossible?
- Exploring the future of occupational healthcare
- Ethics and MyData — from theory to practice
- Is Your Personal Data Used to Influence Your Actions?
- Openness Empowers Individuals and Societies
- BioDI: Mitä yliopisto ei opettaut minulle? - Kirjoitus Aalto-yliopiston Bioinformaatioteknologian kilta Inkubion lehdessä S’napsissa 3/2015.

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.
Achievements related to open data
- Datademo funding for the helsinki and gisfin packages. Details (in Finnish) here and here. I was also interviewed in Citiscope and in a video.
- Apps4Finland 2013: Third place in the visualization category with the Alueellinen hyvinvointi-visualization that was developed together with Juha Leppänen and Satu Korhonen from Demos Helsinki think tank. Details (in Finnish).
- Apps4Finland 2012: Victory in the data opening category (official and audience votes): Data elections (Datavaalit). Details (in Finnish).
- Apps4Finland 2012: Victory in the data guide category (audience votes): Finnish data wiki. Details (in Finnish).
- Apps4Finland 2011: Victory in the data opening category (both official and audience votes): sorvi - R toolbox for open data. Details (in Finnish).
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.
- ProbCMap - Source code related to article Probabilistic drug connectivity mapping
- ICMg - Interation component model for gene modules. R packge related to article Searching for functional gene modules with interaction component models. ICMg is also included in the Netresponse package.
- Eyediagram - Code for creating eyediagram visualizations
Here some selected publications. See all of my publications in Google Scholar.
