Hello!
My name is Arie, from Seattle Washington. I work at the Bill and Melinda Gates Foundation on polio eradication, where we use the ODK suite of tools to help find and report the last polio cases, and then the monitor vaccination programs that prevent spread of the disease (see more here: http://polioeradication.org/). I first started using ODK with Yaw in South Sudan back in 2014, and have been hooked since.
When I'm not collecting data, I'm analyzing it (I'm a statistician by training, specializing in machine learning), and when I'm not working on data, I try to get out and about in the beautiful pacific north-west of the US, preferably mountain biking or rock climbing.
Fun fact: I was the former paper airplane champion of Quebec, a title which I won by accident and have since failed miserably in my one meager attempt to hold on to it. It's also a great teaching example for statistics! See 'the winner's curse' or 'regression to the mean'.
