Calla, an Assistant Professor, teaches Environmental Science and conducts research in hydrology: how to manage our water resources so that we have enough to drink and grow crops. After failing a math placement test in 8th grade, she was afraid of math for years -- until she took calculus in college and discovered she was good at it!
Hydrologists study water and the water cycle. They study the movement, distribution, and other properties of water, and they analyze how these influence the surrounding environment. They use their expertise to solve problems concerning water quality and availability, for example.
In some states, hydrologists need a license to practice. Requirements vary by state, but they typically include minimum education and experience requirements and passing an exam.
