Bio

After completing my degree in Mathematics at the University of Warwick and serving in the military at a U.S. Army base in Korea, I began my teaching career in South Korea, where I formally entered the world of IB Mathematics. Since then, I have taught students from diverse backgrounds and later moved to Denmark to broaden my international teaching experience. Now, I am excited to join the UWC Dilijan community and embrace its mission of bringing together students from around the world through education.

As a mathematics teacher, I am passionate about making complex ideas accessible and meaningful. I enjoy combining technology with student-centred learning to create lessons that are engaging, efficient, and enjoyable. I see mathematics not only as a subject for developing problem-solving skills but also as a way of building resilience, curiosity, and confidence. My greatest satisfaction comes from seeing students discover their own potential and grow into independent thinkers.

What is your favourite part of the course you teach?
My favourite part of teaching mathematics is helping students experience those "everything clicks" moments. Mathematics is far more than finding the correct answer; it is about developing a way of thinking. I enjoy guiding students to discover patterns, connect ideas, and build intuition rather than simply memorising methods. Over the years, I have developed a balance between teaching and coaching: first providing students with the tools they need, then challenging them to think independently. Watching students become confident problem-solvers is one of the most rewarding parts of my work.

Which teaching method do you prefer and why?
I believe in a student-centred classroom where students actively construct their understanding rather than passively receive information. My lessons adapt to students' needs and encourage them to compare different problems, identify common mathematical principles, and explain their thinking. I also enjoy integrating technology, visualisations, and carefully designed resources to make learning both efficient and engaging. My goal is not simply to prepare students for examinations but to develop mathematical thinking that they can apply well beyond the classroom.

Who is your role model or mentor?
My greatest role model is my mother, who also worked in education and inspired my passion for teaching from an early age.
Professionally, I have been greatly inspired by Tim Garry, whose decades of experience teaching IB Mathematics have shaped many of my own ideas about mathematics education. His emphasis on deep understanding rather than rote learning continues to influence my teaching today.

On a personal level, my wife inspires me every day by reminding me to approach challenges with curiosity, patience, and optimism.

What is your life motto?
Aim for the Sun. Even if you fall short, you may still reach the Moon.

I believe setting ambitious goals encourages us to grow far beyond what we initially think is possible. Having people to care for—my family and my students—gives purpose and direction to that journey.

What are the three things you can't imagine your life without?
My family
My iPad
The Internet (a gateway for learning, creativity, and connecting with others)

What do you like to do in your spare time?
I enjoy going to the gym, exploring different cuisines, spending quality time with my wife, and developing educational technology and programming projects for mathematics teaching. I also love discovering new tools and ideas that can make learning more interactive and enjoyable for students.
