Roundtables: Meet the 2025 Innovator of the Year

Every year, MIT Technology Review selects one individual whose work we admire to recognize as Innovator of the Year. For 2025, we chose Sneha Goenka, who designed the computations behind the world’s fastest whole-genome sequencing method. Thanks to her work, physicians can now sequence a patient’s genome and diagnose a genetic condition in less than eight hours—an achievement that could transform medical care.

3 Things Caiwei Chen is into right now

A new play about OpenAI

I recently saw Doomers, a new play by Matthew Gasda about the aborted 2023 coup at OpenAI, here represented by a fictional company called MindMesh. The action is set almost entirely in a meeting room; the first act follows executives immediately after the firing of company CEO Seth (a stand-in for Sam Altman), and the second re-creates the board negotiations that determined his fate. It’s a solid attempt to capture the zeitgeist of Silicon Valley’s AI frenzy and the world’s moral panic over artificial intelligence, but the rapid-fire, high-stakes exchanges mean it sometimes seems to get lost in its own verbosity.

Themed dinner parties and culinary experiments

The vastness of Chinese cuisine defies easy categorization, and even in a city with no shortage of options, I often find myself cookingnot just to recapture something closer to home, but to create a home unlike one that ever existed. Recently, I’ve been experimenting with a Chinese take on the charcuterie boardpairing toasted steamed buns, called mantou, with furu, a fermented tofu spread that is sharp, pungent, and full of umami.

Sewing and copying my own clothes

I started sewing three years ago, but only in the past year have I begun making clothes from scratch. As a lover of vintage fashionespecially ’80s silhouettesI started out with old patterns I found on Etsy. But recently, I tried something new: copying a beloved dress I bought in a thrift store in Beijing years ago. Doing this is quite literally a process of reverse-engineering—­pinning the garment down, tracing its seams, deconstructing its logic, and rebuilding it. At times my brain feels like an old Mac hitting its CPU limit. But when it works, it feels like a small act of magic. It’s an exercise in certainty, the very thing that drew me to fashion in the first placea chance to inhabit something that feels like an extension of myself.
