Dean's Message

This academic year, we are celebrating 150 years of inquiry, innovation, and impact at GSAS. As we look back over our history, I am amazed by what GSAS alumni have accomplished thanks to their tireless dedication to the creation of new knowledge. Across disciplines, GSAS graduates have pushed the boundaries of what we know, helped tackle intractable problems, made discoveries that have changed how we live, and advanced our understanding of the world and our place within it. 

In this issue of Colloquy, you will read about several of your fellow graduates and their pathbreaking achievements. And throughout this sesquicentennial year, we will tell additional stories about our extraordinary community—past, present, and future—including alumni whose GSAS education laid the foundation for incredible impact and the promising students who will go on to accomplish even more. These stories, as well as information about the celebration, our history, and events, can be found at gsas.harvard.edu/150, on GSAS’s YouTube channel, and on our Twitter, Facebook, and Instagram pages.

Alumni Interviews

Empowers Scholars to Reach the Unknown

A little rock can tell the story of the solar system. That’s what drew Yaray Ku PhD ’22 to the Graduate School of Arts and Sciences (GSAS). When she began her research in earth and planetary sciences, Ku wanted to uncover celestial origins. Her advisor guided her to the study of meteorites. Ku became fascinated with the chemical composition of chondrites—meteorites that haven’t been heated to a melting point— and devoted her thesis to comparing them to Earth rock.“We believe these chondrites contain the initial composition of our solar system,” she says. “Studying isotopic compositions in meteorites tells us the story of Earth and the universe—and that story is four and a half billion years old.”
