Passionate about biology and building sustainable solutions, Qiulin Zhu is a Columbia PhD student making waves at Flash Grüb. This week, we’re shining a light on her journey and how she’s helping turn food waste into meaningful change. Let’s get into it. 🌱🔬💬
What made you want to intern at
Flash Grüb?
I was surprised by how much relationship-building goes into grassroots food sustainability work.

As someone who cares deeply about both public health and systems change, the idea of intercepting food waste and turning it into access felt like a tangible, high-impact way to contribute.
How does working on FG fit into your Columbia journey or goals?
My Columbia experience has centered around using science and advocacy to drive real-world change. Flash Grüb allowed me to step outside the lab and work directly with communities—applying strategic thinking in a space that blends sustainability, equity, and innovation. It’s also pushed me to think more creatively and compassionately, which I believe is essential for any future path I take.
In one word, how would you describe Flash Grüb?
Impactful.
