Irena M.

Instructor

Irena is a senior at University High School. One of her fondest memories of early math is of practicing the multiplication table in the car with her dad on the way to school, and that solid foundation has enabled her to now take math classes at IVC. Her passion for STEM and outreach has led her to coach local middle school Science Olympiad teams and organize STEM events for younger children as part of a high school club. Through these experiences, she has discovered a genuine love for mentorship, finding it especially rewarding to watch a student's confidence grow once a difficult concept finally clicks. Irena intends to pursue neuroscience at university, drawn to the way the brain bridges the analytical rigor she loves in math with the deeper questions of human behavior and cognition.

Besides academics, she loves to go for hikes, read, and travel, activities that she credits with keeping her curious and grounded outside the classroom.
