Twelve Women Who Rewrote the Rules of DiscoveryKinga Bali · Edition #4
In genetics, XX is the code for life. In history? It’s the symbol left out of most footnotes.
But in science, XX means women who rewrote the rules. Who entered locked systems and changed the circuitry. Not by asking for entry. By proving the infrastructure was flawed—and rebuilding it themselves. They weren’t featured. They weren’t added. They were essential. This is Edition #4 of Boost Her Voice. Twelve more stories that power the world you live in.
Reshma Saujani – The Woman Who Made Coding a Movement
In a tech world built by men and for men, Reshma Saujani built something else—a pipeline of girls who never asked permission to belong. When she launched Girls Who Code in 2012, coding bootcamps were for the already-initiated. She saw the gap earlier: before girls opted out of STEM, before they met resistance in hiring. The system failed them long before adulthood. She started younger.
Her program didn’t just teach code. It taught courage. Students learned algorithms and recursion, yes—but also how to be loud, how to lead, how to resist erasure.
More than 500,000 girls have now come through her programs. Many have gone on to major in computer science. Some have become CTOs. Others founded startups before 20. She didn’t ask tech to make room. She made the future too full of women to ignore.
Jennifer A. Lewis – The Engineer Who Printed the Impossible
If biology is the code of life, Jennifer A. Lewis learned how to print the hardware. A materials scientist and inventor, she pioneered a form of 3D printing that didn’t just layer plastic—it layered function. Her lab developed printable inks that conduct electricity, carry live cells, and form flexible circuits. She printed synthetic tissues, soft robotics, and batteries as small as a grain of sand.
Before Lewis, 3D printing was flashy. After her, it became foundational. Her work made it possible to fabricate organ-like systems, print electronics directly into wearables, and deliver medicine with programmable precision. What she created wasn’t a new tool. It was a new category. She didn’t upgrade the future. She prototyped it—one nanolayer at a time.
Anne Wojcicki – The Woman Who Put DNA in a Box
She took one of the most guarded scientific resources—the human genome—and dropped it in your mailbox. Through 23andMe, she turned genetic testing into a consumer product. A vial of spit became access to your ancestry, inherited diseases, health risks, and future uncertainties. What was once gatekept by labs and specialists became intimate—and public.
It sparked backlash. Medical boards bristled. Regulators intervened. But the shift had begun. Genomics was no longer just academic. It was personal. Wojcicki didn’t just make health data legible. She made it a question of ownership: Who gets to know? Who gets to decide? She turned science into something you could hold—And made institutions sweat in the process.
Sheila Widnall – The Physicist Who Took Flight
Before she made history in the Pentagon, Sheila Widnall was shaping the sky.
Her research in fluid dynamics advanced how we understand airflows, turbulence, and lift—principles essential to modern flight. She became the first woman in MIT’s School of Engineering. And in 1993, she became the first woman to lead a U.S. military branch as Secretary of the Air Force.
But she never stopped being a scientist. While managing military budgets and policies, she continued to publish academic papers. She bridged physics and power without apologizing for either. Widnall didn’t adapt to male systems. She led them—with equations in one hand and authority in the other.
Vivienne Ming – The Scientist Who Rewired Intelligence
Vivienne Ming doesn’t build AI to make systems faster. She builds it to make people freer. A theoretical neuroscientist turned tech entrepreneur, Ming develops tools that solve systemic problems—algorithms that reduce hiring bias, predict school dropouts, personalize mental health care. She’s not interested in dashboards. She’s interested in impact.
Her companies don’t chase scale. They chase possibility. She codes as a provocation: What if intelligence wasn’t defined by a test, but by what it could do for others?
She’s proof that ethics doesn’t come after innovation. It leads it—if you build for the people systems leave out.
Pardis Sabeti – The Virus Hunter Who Raced the Clock
When Ebola broke out, most systems were too slow. Pardis Sabeti wasn’t.
Her lab deployed real-time genome sequencing during the 2014 West Africa outbreak—tracking how the virus mutated and spread while governments were still debating response. The data saved lives. And it changed how we fight pandemics.
Sabeti is a physician, a computational biologist, and a Rhodes Scholar. But her impact is structural. She’s building models that make science move at the speed of crisis—not peer review. In a world built for academic delay, she made urgency a method.And proved that precision doesn’t have to pause.
Regina Barzilay – The Woman Who Trained AI to Save Lives
When Regina Barzilay survived breast cancer, she didn’t return to her work—she weaponized it. A leading figure in natural language processing, she developed AI systems that read mammograms better than radiologists. Her models now detect early-stage cancer, forecast patient risk, and help doctors plan treatment with unprecedented accuracy.
She also created tools that let machines “read” scientific literature—accelerating drug discovery and trial design. She didn’t just build smarter machines.She made them act faster, read deeper, and fight back—against the disease that nearly took her life.
Sangeeta Bhatia – The Engineer Who Made Medicine Tiny
Sangeeta Bhatia doesn’t build theories. She builds tools—tiny, invisible, life-saving tools. Trained in both medicine and engineering, she’s created synthetic microlivers to test drug toxicity without human trials. Cancer-detecting nanoparticles that travel through the bloodstream. Diagnostic strips that don’t need power, refrigeration, or infrastructure—just a drop of fluid and a question to answer.
Her work lives in the overlap: biology, nanotech, microfluidics. It’s not flashy. It’s surgical. It shows up where high-tech usually doesn’t—rural clinics, fragile bodies, low-resource environments.
Bhatia didn’t just make medicine smaller. She made it smarter, faster, and finally able to reach the people who needed it most. She isn’t shrinking science. She’s scaling healing.
Joy Buolamwini – The Researcher Who Made AI Face ItselfJoy Buolamwini ran facial recognition software on her own face. It failed.
That failure exposed something far bigger: most commercial AI systems didn’t recognize dark-skinned faces—especially not women. The datasets were biased. The outcomes were worse. And the people most affected were nowhere in the room.
She founded the Algorithmic Justice League to change that. Her research exposed how major tech companies were deploying flawed systems into policing, hiring, and surveillance—without accountability or consent.
The pushback was loud. But her data was louder. Her TED Talk went viral. Her research forced Amazon, Microsoft, and IBM to pause their facial recognition programs. Congress listened. So did regulators.
She didn’t come to warn.She came to prove. And once she did, there was no unseeing it.
She made bias visible—at machine scale.And demanded tech reckon with the people it was built to ignore.
Frances Arnold – The Chemist Who Taught Nature to Improvise
Frances Arnold didn’t wait for nature to evolve the perfect molecule—she made evolution happen in a lab. In the early ’90s, she pioneered directed evolution, a process that mimics natural selection to develop new enzymes. These aren’t just scientific curiosities—they’re tools. Tools that cleanly produce biofuels, synthesize new drugs, and replace toxic industrial processes with precision chemistry.
She took what nature does slowly, messily, and sometimes inefficiently—and turned it into a repeatable method that changed the way we make things. In 2018, she won the Nobel Prize in Chemistry for it—the fifth woman ever to do so. But Arnold’s breakthrough wasn’t just the enzymes. It was the idea that randomness, when guided with clarity, can be engineered into something brilliant. Today, her work sits at the core of sustainable chemistry, green energy, and medical manufacturing. Her method has become a foundation of modern biotech. She didn’t break the rules of biology. She taught them to adapt—on command.
Marian Croak – The Engineer Who Made the Internet Speak
When the internet was still mostly text and static images, Marian Croak asked a different question: What if voices could travel through it? She led the development of Voice over IP—technology that turned speech into data and made digital communication what it is today. If you've ever made a call over Zoom, WhatsApp, or Wi-Fi, you're standing on her work.
She holds more than 200 patents. But she didn’t stop at invention. She used her position at AT&T, and later at Google, to open doors that weren’t meant to open. She’s built systems for emergency communications, developed tools for disaster recovery, and funded pathways for Black engineers and women in tech. Croak doesn’t shout. She builds quietly, constantly—until you realize everything’s running on what she made possible. She didn’t just connect voices. She gave them reach. And then made sure the right ones got heard.
Barbara McClintock – The Geneticist Who Refused to Be Erased
In the 1940s, Barbara McClintock discovered something no one believed: genes can move. Her research showed that genes weren’t fixed instructions—they could jump, switch on or off, and reshape traits in real time. It challenged everything biologists thought they knew. And it got her sidelined. Funding dried up. Labs stopped returning her calls. She was dismissed not because her work lacked rigor—but because she refused to explain it in ways that made men comfortable.
So she worked alone. For decades. No recognition. No validation. Just data.
In 1983, at age 81, she received the Nobel Prize in Physiology or Medicine. The world finally admitted she’d been right all along. She didn’t claw her way back into the spotlight. She made the truth so undeniable that the spotlight had to follow. Barbara McClintock didn’t argue. She just outlasted them—with better science.
48 stories told. 576 still waiting. They didn’t ask for the spotlight. They built the infrastructure of discovery. Still think recognition is optional?
