"I am a member of the faculty in the mathematics department at San Diego State University. My research, teaching, and service activities all focus on how we can improve mathematics learning for all students, especially English Learners and students from  groups underrepresented in STEM fields. I enjoy teaching and working with students from across grade levels, from middle school all the way through graduate school.”
