I just finished my Ph.D. in Earth and Planetary Sciences from Yale University. My research focused on the early processes in the solar system using both theoretical and experimental methods.

I worked as a teaching fellow in Yale University from 2020 to 2024. I mostly worked with undergraduate students. I mainly conducted weekly office hours in-person or via Zoom to help students with their homeworks and answer their questions about what they learnt in class. I also graded their assignments and exams, provided feedback.

In Fall 2020 I taught Fossil Fuels and World Energy and the class size was ~20. This course requires students know algebra and applied math. They needed to do practices like calculating energy consumptions and converting units. All the office hours, individual meetings gradings were conducted online.

In Fall 2021 I taught Dynamic Earth, which was a course combining math, thermodynamics and geology and the class size was over 200. Students needed to use their knowledge of material sciences and geology to explain observations like volcano eruption and formation of islands.

In Spring 2023 and 2024 I taught Global tectonics and the class size was 30-40. This was a course that focused on structure geology and requires knowledge of math, thermodynamics, geometry, physics, mineralogy, etc. Students needed to combine their knowledge of material science, geology and physic, and using math as a tool to solve the problems like the buoyancy of mountains over the mantle and the elevation of plateaus after erosion.

Earth Science

Earth Science

I finished my PhD in Earth and Planetary Sciences from Yale University, where my research focused on planetary materials and the evolution of the early solar system. I have extensive experience teaching and tutoring topics such as geology, environmental science, plate tectonics, and planetary processes at both college and high school levels. My background combines strong analytical and experimental skills with a passion for helping students understand how Earth systems work and how they connect to broader planetary science. I enjoy making complex scientific ideas clear, engaging, and relevant to students’ daily lives and interests.
Physics

Physics

I earned my PhD in Earth and Planetary Sciences from Yale University, where my research involved applying physics to planetary processes. I have taught and tutored physics at multiple levels, focusing on helping students build strong conceptual foundations and problem-solving confidence.

Great at explaining everything!

Heidi is good at explaining everything I needed clarification on! I hope to continue to work with Heidi in the future.
