Kelly Gaier Evans Headshot

Kelly Gaier Evans aims to open doors and opportunities for students across Ohio. She started her career with the Education and Philanthropy team at Battelle in 2012 as a STEM Project Specialist. Currently, she serves as the Director of the Ohio STEM Learning Network for Battelle and works to expand access to quality STEM education for all students across Ohio.

At Battelle, Gaier Evans has spent the past ten years managing STEM teacher professional development experiences for teachers across Ohio and multiple states across the STEMx network. A certified Project Management Professional, she has managed and led multiple contracts for Battelle including the regional partnership with Code.org. In this role, Gaier Evans managed a team of facilitators as well as deliverables and the project budget. With a team of facilitators, she worked to expand teacher capacity across Ohio to teach foundational computer science to Ohio K-12 students. As director of the Ohio STEM Learning Network, Gaier Evans is finding ways to embed computational thinking and computer science across STEM initiatives.

Prior to joining Battelle, Gaier Evans worked both in the classroom as a high school math teacher and on state level policy at the Ohio Department of Higher Education (formerly referred to as the Ohio Board of Regents). Kelly earned her Bachelor’s degree in Political Science and International Studies from Capital University. She earned her teaching license while teaching in the Delta region of Arkansas.

Kelly unapologetically dominates family games of Settlers of Catan. As someone who loves exploring by foot and kayak, she is on a mission to ensure her daughter shares that love of the great outdoors.

STEM Relationship Manager

Sandra Wilder joined Battelle and the Ohio STEM Learning Network team in 2021 as a STEM Relationship Manager. She believes that STEM education is a pathway to students experiencing, learning, and applying academic content in an authentic and relevant manner. Sandra considers engaging teachers in dynamic and personalized professional learning to be one of the key approaches to creating such pathways. When we invest in educators, when they are supported and encouraged, they successfully create learning environments of excellence that their students deserve.

Sandra holds a bachelor’s and a master’s degree in Applied Mathematics. During her time at the University of Akron, she fell in love with education, which led to earning a doctorate in Secondary Education. Her experiences as an educator at secondary and post-secondary levels (at both urban and suburban institutions), as well as a pre-service and in-service teacher trainer, have fostered Sandra’s passion for positioning all students and educators as capable of success in STEM related fields.

To her two sons’ delight, Sandra loves baking. Equipped with a good supply of cookies and cakes, the family can often be found enjoying board games and taking long walks.
