Irena M.

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. Fun fact: she's attended 10 different schools, counting kindergarten, an experience that has made her especially adaptable and quick to feel at home in new environments. Whether she's tackling a new trail, getting lost in a novel, or exploring a new city, Irena approaches each experience with the same enthusiasm and open-mindedness she brings to her schoolwork and outreach efforts. As she looks ahead to college, she hopes to continue combining her scientific curiosity with her commitment to community, carrying forward the lessons in patience and encouragement she's learned from coaching younger students.

Ryan H.

Ryan is a second-year student at UCI currently studying to earn a degree in mathematics. From a young age, Ryan knew he wanted to do math and stood out early. Many of Ryan's friends growing up had strengths that lied outside of math, and Ryan became accustomed to helping his friends and peers with understanding difficult math concepts. He began working with younger students too and found intrinsic reward in helping those who were younger and discouraged to become interested and excited by math. He has 3 years of tutoring experience and 2 years experience working with kids outside of tutoring, which has taught him how to meet each student where they are and adapt his explanations until concepts truly click.
