Chris Sutherland

Chris Sutherland

CEO/Founder, Physics Ph.D.

As a physics lecturer, Chris has taught over 1,000 students across 20+ freshman physics sections at the University of Southern California, earning a 4.9/5 rating on Rate My Professor with 80+ reviews.

PhysicsGraph is inspired not only by Chris' PhD in the field, but also by his experience as head mentor and lecturer at the Quantum Cryptography School for Young Students at the University of Waterloo. Since then, he has always wondered: why can't we start teaching physics earlier, and at an accelerated pace?

Deeply passionate about education, Chris was not satisfied operating within the academic system as he felt it was not giving every student the personalized learning journey they need to reach their full potential, which is why he decided to start Lemnisket.

Our Mission

Since that first experience Chris had teaching quantum to high schoolers, he's been in love with teaching, and more specifically with the problem of how to teach things in the most efficient and effective manner to avoid student burnout.

This drives everything we do at PhysicsGraph - combining rigorous academic standards with cutting-edge learning science to make physics accessible to everyone.
