Research and Scholarship
Interests
My research area is in mathematics education. I am interested in students' beliefs and attitudes about mathematics and how those relate to identity, interest, and persistence in STEM. I am also broadly interested in statistics and mathematical modeling education.
I am a quantitative analyst currently working with national survey data from the High School Longitudinal Study of 2009 (HSLS:09).
