Recognition

In 2018, Heubach won the California State University system's Faculty Innovation and Leadership Award, becoming the first professor at the Los Angeles campus of the system to be so honored. The award honored her educational initiatives including developing a new sequence of mathematics courses for life sciences students, developing flipped classroom mathematics courses, and improving statistics courses used to fulfill general education requirements.
