She filed her first medical device patent before she could legally drive. Now she's trying to turn aging into a number you can read off a cheek swab.
Most people answer that question with a birthday. Alina Su thinks the birthday is the least interesting number on you. Her company, Generation Lab, takes a cheek swab, reads the methylation patterns in your DNA, and hands back a different age - the one your organs actually believe.
The premise is blunt. Generation Lab analyzes 460 biomarkers across 21 organs and systems, looking for what the science calls noise: the slow dysregulation of cytosines that were supposed to stay constant for life. When the noise climbs, the body is drifting. The plan is to catch that drift early enough to do something about it.
"We recognize that if we can solve aging as a problem," Su told Inside Precision Medicine, "then we can reverse the diseases that are going to potentially happen." It is a big sentence from a young founder, and she says it without flinching.
She is the commercial half of a deliberate pairing. The science came out of two decades of work in the Conboy Lab at UC Berkeley. Su's job is to get it out of the lab and onto a kitchen table, priced like a subscription rather than a clinical trial.
As rejuvenation research expands, we need to focus on identifying the most effective measurement for aging.
Generation Lab is Su's second act, and the first one was about pain. Her startup NovaXS built Telosis, a needle-free injection platform meant to make self-administered medication hurt less. The product entered clinical trials on the road to FDA approval. The thread that runs through both companies is the same: take a miserable, gatekept piece of healthcare and make it something a person can handle at home.
The pivot to aging wasn't random. Su was a researcher in Irina Conboy's lab at Berkeley before she was a CEO of anything in longevity. "My passion in healthcare led me to focus on Aging & Regeneration since I was a researcher in Irina's lab at Berkeley," she has said. When she co-founded Generation Lab, she did it with that same mentor - the academic who spent twenty years on rejuvenation now sitting beside the former student who wanted to sell it.
To build it, she stepped away from a Harvard Medical School PhD in aging and regeneration. Leaving a doctorate at Harvard to chase a company is the kind of decision that reads cleaner in hindsight than it felt at the time. She's on leave, not graduated, which tells you where her bet is.
Generation Lab's read on aging is "biological noise." Certain cytosines in your DNA are supposed to stay put your whole life. When they don't - when the methylation pattern starts to scramble - that dysregulation acts as a clock. Generation Lab measures methylation at specific CpG sites and maps the drift to organ-level risk for metabolic, cardiac and cancer conditions. It isn't a diagnosis. It's an early-warning gauge.
In her words: "We're measuring the methylation levels on specific CpG sites, which is a specific gene that relates to aging. We can tell you that these are the risks that you can work on and you can reverse that before the disease."
Su didn't build Generation Lab alone, and the lineup is the tell. Her co-founder and Chief Scientific Officer is Dr. Irina Conboy, the UC Berkeley bioengineering professor known for parabiosis rejuvenation work and the source of the science. The third seat belongs to Michael Suswal as COO, who previously co-founded Standard AI, a computer-vision company once valued at $1.5 billion.
Then there's the advisory bench, which is where a small startup signals its ambition. Generation Lab lists geneticist George Church of Harvard and Aubrey de Grey, the longtime evangelist of radical life extension. That's a lot of gravity around a cheek swab - and a lot to live up to.
The model is a subscription: entry-level plans landed around $400 a year for repeat tests, the idea being that biological age is only useful if you watch it move. A single snapshot tells you where you are. The point is to see whether what you're doing - the diet, the drug, the intervention - is bending the curve.
From reactive to proactive - medicine that arrives before the diagnosis.
Strip away the biomarkers and the brand, and the aspiration is plain. Su wants to move healthcare upstream: catch the drift before it becomes a disease, and make that catch cheap enough that it isn't a luxury. Generation Lab calls the goal "the ageless generation." It's the same instinct that drove her to make injections hurt less - take something locked behind a clinic and hand it to the person it belongs to.
Her first patent came before her first driver's license. Age 15.
She co-founded a company with her own former lab mentor - the student turned the professor's research into a product.
The science treats "noise" as the signal: DNA that was supposed to hold still, and didn't.
Her COO once built a $1.5B computer-vision company. Her advisors include George Church.
She has a dog named Han Han.
Six patents across the U.S. and China, with more applications still pending.
