2019 research opportunities will be announced closer to the 2019 festival.
Many researchers take advantage of the large number of twins at the festival to help with their projects. Research activities might include filling out surveys, having your picture taken even providing DNA samples. It depends upon the nature of the product.
Most researchers will offer some modest compensation (gift bags, product or financial stipend) in exchange for your time. The Research Plaza is located on the Twins Days Festival grounds, near the tennis courts.
