Teaching

I teach physics and gravitational-wave data analysis with an emphasis on conceptual clarity, hands-on computation, and research readiness.

My teaching has ranged from introductory classical mechanics and special relativity to gravitational-wave data-analysis workshops for students entering the field. I also mentor undergraduate and postgraduate researchers on gravitational-wave projects, with a focus on helping students move from technical exercises to publishable research.

The common thread is that I try to make the material operational. Students should leave with a framework they can use in a problem set, a notebook, or a research pipeline, not just a definition they can repeat back.

Selected student comments
“Alvin was awesome! Very well prepared and kind with a great understanding.”
“He was the best and most enthusiastic TA I had this semester, by far. He was always prepared and made time to answer my questions, as well as all other students. Additionally, he attended all of the lectures, which is probably a major reason why he was so prepared in office hours.”
“Alvin, thank you for your great support throughout the entire course. I really appreciate it. And I really enjoyed chocolates and sweets that you gave us. I hope that all the best things in life come your way and that you have a great life ahead.”
“Alvin is the single best TA I've ever had. You, with your "lecture notes", single-handedly helped me turn around my grade from a disaster to a modest B+! I couldn't have done this without your help. From the bottom of my heart, thank you so much for all you do.”

Taught foundational concepts in gravitational waves and data analysis in an intensive summer-school format.

Olympiad coaching Po Leung Kuk Tang Yuk Tien College, 2016 - 2018
Coach, High School Physics Olympiad Team

Taught calculus-based classical mechanics for advanced secondary-school students preparing for the Hong Kong Physics Olympiad. I built a structured training sequence covering vectors, limits, differentiation, integration, multi-dimensional motion, curvilinear coordinates, Newtonian mechanics, torque, angular momentum, energy, momentum, and simple harmonic motion.

The course materials included handwritten lecture notes, weekly problem sets, progress tests, mock papers, and supplementary readings designed to bridge school physics with first-year undergraduate mechanics.

Educational Works

NSS Physics Insight - A short introduction to Special Relativity was written by me with Y. Y. Pang as undergraduate students, originally as a course final project. It is a self-study textbook for NSS students and junior undergraduate students. It was presented at the 1st CUHK Physics Student Conference.

After that, Professor Chu Ming Chung and Dr Leung Po Kin encouraged us to polish the work further and publish it through the CUHK e-learning project. The preface captures that path from class project to published outreach textbook, as well as the help we received from Lin Lap Ming, P. K. Leung, and CUHK Physics.

Imaging a Black Hole: The First Image Captured by Scientists is a CUHK Physics outreach booklet written as a companion to Dr. Po Kin Leung's public lecture. I prepared the notes and emceed the talk so that mainly high school participants could follow the physics from escape velocity, to gravitational redshift, to Schwarzschild black holes, and finally to the interferometric idea behind the EHT image of M87.

Caltech

ARC Course Teaching Compliment

California Institute of Technology, 2022-23

Student-collected recognition for Ph 106a teaching, office hours, review sessions, and shared notes.

View the original compliment card Original ARC course compliment card from 2022-23
Alvin was one of the TA's this year for Ph 106a. I consistently attended his office hours, and he would often spend almost an hour past the 2 already scheduled hours to ensure that students were understanding the content both for the sake of solving problems and on a deeper conceptual level. Alvin also held review sessions for both the midterm and the final, and provided us with his own summative notes (about 100 pages) to help us prepare for the exams. I was consistently impressed with his dedication to students' understanding and him going above and beyond in his role.
