Bio

Bill Zahner is a professor in the mathematics department at San Diego State University and the Director of the Center for Research in Mathematics and Science Education. Zahner's research is focused on improving mathematics learning for all students, especially multilingual students who are classified as English Learners and students from historically marginalized communities that are underrepresented in STEM fields.

Zahner's work has been supported by the National Science Foundation, the State of California, and the Spencer Foundation. He is currently PI of one grant funded by the English Learners Success Forum, and co-PI of two projects funded by the National Science Foundation.
