Crowd-Powered Personal Decision Support Systems

I designed, developed and tested with end-users an online tool for personal decision support.

In 2015, I won a highly competitive (accept rate ~10%) Academy of Finland postdoctoral grant for three years. This was the first ever postdoctoral grant from Academy of Finland to crowdsourcing.

Since the project, the tool I created has been found useful across a plethora of use cases and in investigating different ways of providing decision support, including AI-based conversational approaches in the early 2020s. The tool, AnswerBot, has been used by tens of thousands of end-users, across problems in software engineering and especially healthcare: Parkinson’s Disease, Low Back Pain, Mental Health, or e.g. healthy dieting options.

During the project, I also collaborated with researchers from Tokyo University, Japan, and Oxford, UK, just to name a few.
