Workshop on Citizen Science and Crowdsourcing

What do a lawyer, materials scientist, funding advisor, historian, computer engineer, librarian and sociologist have in common? Their curiosity for crowdsourcing ! 15 participants attending the Workshop on Citizen Science and Crowdsourcing that I (co-)conducted on May 17th, 2019 for which we (my colleagues Deniz Iren and Arthur Jochems) won an award from Universiteitsfonds Limburg.

I started by introducing participants to the theory and fundamentals behind crowdsourcing along with popular and successful examples. Then, I provided them hands-on experience of being a requester and designing and executing a live microtask on the Figure Eight platform. Next, we gave the participants the opportunity to experience also being the crowd. My colleague Deniz Iren created an interface that allowed them to contour tumors on lung cancer images! Check out our project details here.

We received positive feedback and already an email from a participant saying “Thanks again for organzing the event today, it really opened up my eyes towards crowdsourcing and its possibilities”😀

Workshop materials are available here:
