I am a Physics and Mathematics tutor with 8 years of experience helping students from middle school through college. I graduated summa cum laude from Stanford University with a Bachelor's degree in Physics and a minor in Mathematics.

My teaching style is focused on ensuring strong foundational understanding. I begin by identifying any gaps or misconceptions in a student's knowledge and spend time solidifying the core principles through practice problems and demonstrations before moving on. Students learn best when they understand the basic concepts thoroughly before attempting to apply them.

I have a strong passion for helping students see the natural beauty in numbers and formulas. Problem solving skills developed in physics and mathematics are invaluable tools for critical thinking across any field. It is deeply rewarding for me to see the lightbulb moments when students make connections between concepts.

In my free time I enjoy reading popular science books and keeping up with the latest research. I also love hiking, playing volleyball, and tinkering with simple Rube Goldberg-style machines. I look forward to working with you to build confidence and mastery in these foundational STEM subjects.

What makes my science, physics, and math lessons unique is my focused approach on strengthening conceptual understanding. Too often, students struggle not because they aren't smart, but because they have gaps in their foundational knowledge or misconceptions that were never properly addressed. I spend time at the beginning of our sessions evaluating each student's strengths and weaknesses to identify any areas they are shaky on. From there, I develop personalized lesson plans that guide students through building up their knowledge from the ground floor. We spend as long as needed on each new concept through demonstrations, examples, and problem-solving until mastery is achieved. This approach means that students retain information better and are able to confidently apply what they've learned to more advanced problems. It also prevents frustrations and roadblocks down the line by eliminating any cracks in their foundation. My goal is to give students a deep, comprehensive knowledge of these subjects that will serve them throughout their continuing education and careers.
