For those who aren't aware, Columbia’s Graduate School of Arts and Sciences (GSAS) requires all PhD students to teach during their program. But for some doctoral students, it’s more than just a requirement - it’s a calling. One of those students is our very own Joseph Lee, who’s been selected for the 2026 Presidential Award for Outstanding Teaching by a Graduate Student.

This year marks the award’s 30th anniversary, and since its founding, any University graduate student at Morningside Campus or CUIMC who has been appointed to an instructional position is eligible to be nominated. However, the award is bestowed to just three graduate students a year. While you can surely do the math to appreciate just how distinguished this award must be, here’s some added perspective: GSAS alone has nearly 1,600 doctoral students, all of whom are subject to the school’s teaching requirement.

But for those who know Joseph, his selection is no surprise. While earning his bachelor’s degree in applied physics at SEAS, he worked as a teaching assistant for a variety of courses and supported Physics faculty member Sebastian Will in designing the Quantum Simulation Lab Course. When he chose to stay at Columbia and pursue a PhD in physics with a focus on quantum optics, teaching was already firmly on his radar (physics pun absolutely intended).

"What changed during graduate school is more how I went about teaching."

His passion for pedagogy is evident as soon as you bring up teaching. Reflecting on how his approach to the classroom evolved since his undergraduate TAing days, Joseph explains that in graduate school, “I focused more on teaching students to be self-sufficient and engage in social learning. In the last few classes I was a teaching assistant for, I wanted the students to spend more of their time working together.”

To be clear, Joseph has gone beyond simply refining his approach and goals as an instructor, tasks that in and of themselves are hardly simple. As recognized in the citation for his award, he has “led teams of peers, providing guidance and advice for their own teaching practice” and “helped launch and lead a growing program to support incoming undergraduate students who may have felt that they did not belong or could not flourish.”

It's worth pointing out that this is not the first time a Physics PhD graduate student has won the Presidential Award. Indeed, the precedent and the prescience of being selected is on full display with faculty lecturer Rebecca Grossman. She earned her bachelor’s degree in astrophysics from Barnard, and, like Joseph, chose to stay within the Columbia community for her Physics PhD, where she studied black hole orbital planets. In 2006, she, too, earned the Presidential Award for Outstanding Teaching by a Graduate Student. Today, her interest as a faculty member is, fittingly, “Physics Education.”

Will Joseph follow in Becky’s footsteps as a future faculty member of CU Physics? One can only hope. Regardless, the department and its students have already benefited tremendously from his dedication and hard work. Or as his citation perfectly summarizes: “Your care for students and your encouragement of them to achieve their full potential are widely known, and your students love you.”

Congratulations, Joseph! Thank you for investing as much in the success of others as you do in your own work.
