  • Strasbourg's 2016 Hacking Health Camp

    March 2016

    Hacking Health Camp is an international event dedicated to breaking down the barriers of innovation in healthcare. It includes the largest european hackathon on healthcare. My team came up with a new proposal for the evaluation of surgical risks related to the body fat location and was rewarded with the "best clinical solution" award. This was the most challenging hackathon I've taken part in and I'm still proud of what we've accomplished there.
