She didn't set out to become a mathematician.
When Dr. Bella Tobin started college, she was a nutrition and food science major. After realizing those courses weren't quite the right fit, she switched to undeclared and decided to take a mathematics course called Foundations of Mathematics.
And something clicked.
She loved the way mathematics asked her to think deeply, solve problems and ask questions. Her professors challenged her curiosity, and before long, she was hooked. Years later, after earning her master's and Ph.D. in mathematics, she found herself doing the same thing for her own students.
"There's nothing that brings me as much joy as watching them go through the transition from feeling intimidated by the subject to flourishing."
For Dr. Tobin, that transition is especially meaningful when students enter her classroom convinced they aren't "math people."
She knows the feeling is common. But she doesn't believe it has to be true.
"I don't think that exists," she says. "It's how you've been introduced to math and how it's been communicated to you."
In her calculus courses, she works to change students' mindsets by giving them opportunities to collaborate, ask questions, come to office hours and see themselves as belonging in the sciences. By the end of the semester, students who once expected to struggle are often leaving with a little more confidence in themselves and their ability to do mathematics.
While teaching pre-calculus as a graduate student, Dr. Tobin had a student who was quiet, reserved and nervous about mathematics. Over the course of the semester, she watched the student blossom. Years later, she received an unexpected email: the student had earned a degree in mathematics and was pursuing a Ph.D.
"For me, it was just another semester," Dr. Tobin says. "But it can be a huge deal for the students."
And when she's not teaching or researching, you might find her practicing Brazilian jiu-jitsu, caring for her houseplants, reading a mystery novel or taking a quiet morning walk with her two golden retrievers.
Her advice to college students? Go to office hours more; sometimes a small step into a professor's office can be the beginning of something much bigger.
