Christina Smith is a doctoral student in the School of Chemical, Biological, and Environmental Engineering at Oregon State University. She received her B.S. from the University of Utah in chemical engineering and is pursuing her Ph.D. also in chemical engineering with an emphasis on engineering education. Her research interests include undergraduate and graduate student personal epistemology (their beliefs or frames of knowledge and learning) across STEM fields as well as the diffusion of educational innovations. Christina's primary involvement with the ESTEME@OSU project is to better understand the structure and support provided for graduate teaching assistants (GTAs) and learning assistants (LAs) in the STEM fields, and how they are facilitating cooperative learning in recitations, studios, and labs.
