Visiting researcher from Finland

The math lab is pleased to host Gintas Silinskas from February to April. Gintas comes to us from the University of Jyväsklä in Finland, but he is originally from Lithuania. Heather, Sabrina, and Chang are working with him to analyze a large and exciting data set on home literacy and numeracy of Lithuanian children.

Working together to analyze data in the Math Lab. L to R: Heather, Gintas, Sabrina, & Chang.
