Jessie Antonellis-John

Although Jessie is a life-long lover of number and logic puzzles, she never really thought of herself as a "math person" until she started teaching. Math was so much a part of her life that she never even noticed it! When she started teaching science, Jessie realized that math and science are intertwined, and both are important tools to help you understand the world.

Jessie has a bachelor's degree in astrophysics from Mount Holyoke College in Massachusetts, and a doctorate in science education from the University of Arizona. She taught math and science to college students for most of her career, teaching at tribal colleges in Arizona and Nebraska. Her particular interest as a researcher and educator is ways that students' cultural and personal identities influence their learning of science. When she became a high school and middle school teacher, this focus on students allowed her to create classes that built on students' interests and goals to keep them engaged and motivated.

Jessie is happy to now be a permanent resident of the Pacific Northwest, where she enjoys hiking, sightseeing, and foraging in beautiful Oregon. She lives with her wife and two cats near the Oregon coast, which is a wonderful place for kayaking, fishing, and camping. Jessie also enjoys writing, painting, singing, and acting - but not well!
