    In 2015, Katie was awarded the Math for America Master Science Teacher Fellowship and in 2016 was a NASA Climate Change Research Initiative Teacher Fellow at the NASA GISS research center. Then, in her words, she got tired. And she quit. And she traveled to 32 countries over the course of a year. In 2017, Katie and her husband Sonny (a Govie alum) moved to South Carolina and she began teaching again. Now in her tenth year of teaching she thinks she has the best job in the world, talking about science (and life) with young people, who are just the perfect amount of weird and special.

She believes in creating an active learning environment that has meaning. Her teaching style is dynamic, active, and creative as well as a fun learning environment for her students.
