How did you choose to study physics?As a child I loved putting things together and taking them apart; I designed new toys from my blocks and Legos. I also enjoyed the logical mathematical language and excelled in math and science classes. When it came time to pick a major in college, I leaned towards math and physics because of good professors and the interesting problems we solved. I also like engineering, which allows me to apply my understanding of math and science to real-world problems. Since math and physics are both about solving problems, my undergraduate degree prepared me well to study engineering in graduate school.
What about teaching energizes you?I get excited about cool math and physics problems. But I know that not everyone does. My goal is for students to see what is so exciting about these types of problems. Teaching is also continual learning, and I love learning new information. I get energized when students ask deeper questions about math and physics, even if I don’t have the answer. This means I get to learn something new!
How has your background and educational experience shaped you as a teacher?I strive to be as open as my undergraduate professors were. At the liberal arts school where I received my bachelor’s degree, my professors always had their doors open. I seek to be as welcoming and engaging with my students as these professors were. In graduate school, I attended a large university with some wonderful professors as well. These teachers held me to a high standard, and my understanding of engineering grew deeply during these classes. I seek to create an environment with high standards where students can grow.
