Katherine Muenks studies achievement motivation, or the degree to which people are energized to learn, accomplish their goals, and demonstrate their performance in achievement-oriented environments such as school. In her work, she focuses on how people's beliefs about ability (e.g., How good am I at math? Is my ability fixed or changeable?) are shaped by their own perceptions, the context around them, and social others including parents, teachers, and peers. Muenks also studies how students' beliefs about ability influence their academic performance, choices in school (e.g., major in college), persistence, and well-being.
