Profile

Dr. Hjalmarson holds a Ph.D. in Curriculum and Instruction with a concentration in Mathematics Education from Purdue University. She also has a Masters degree in Mathematics from Purdue University and a B.S. in Mathematics from Mount Holyoke College. Dr. Hjalmarson's research interests include mathematics education and engineering education. She has been awarded multiple NSF-funded projects on STEM faculty development for interactive teaching and engineering learning. In both of these settings, her work focuses on design-based research and models and modeling frameworks for teaching and learning.

She is presently serving as a Program Director in the Division of Research on Learning in Formal and Informal Settings in the Directorate for Education & Human Resources at the National Science Foundation. She currently leads the Discovery Research K-12 program and manages proposals and awards related to mathematics and engineering education across other programs in the Division.
