Kristi Anseth is one of the nation’s leading chemical and biomedical engineers, inventing tissue substitutes that restore or improve function and advance treatments for everything from broken bones to diseased heart valves. Recently, she’s had major breakthroughs in understanding why some cardiac treatments don’t work for women like they do for men. “We saw in many of our tissue-engineered models that the sex of our ‘cells’ mattered,” she said. Anseth is one of a small group of innovators who have been elected to all three national academies — Sciences, Engineering and Medicine.
Alicia Boler Davis
56 | CEO, Alto Pharmacy
Engineer Alicia Boler Davis’ career started at GM, where she became the first Black woman to serve as a plant manager and later rose to executive vice president for global manufacturing. At her next stop, Amazon, she was the senior executive overseeing global fulfillment during the pandemic and the first Black woman to be part of the exclusive “S-Team” leadership circle. Appointed Alto’s CEO in 2022, she guided a digital pharmacy with nationwide mail delivery and courier and pickup services in 12 metropolitan areas. Alto was recently acquired by Paulus Holdings (in a deal that valued Alto between $1 billion – $1.5 billion) and is being operated through the firm’s new Fuze Health brand. Boler’s next stop is a corporation where she once interned: Ford. In October, she’ll become the president of Ford Pro, the commercial fleet division of the automaker.

Since then, she’s overseen the first lab demonstration of a fusion ignition and the lab’s installation of the world’s fastest supercomputer, El Capitan, a $600 million project that began in 2023. Budil started her career at the lab in 1987 as a graduate student and had a three-year stint as vice president for national labs at the University of California Office of the President, before returning to Livermore, Calif. Now with 9,500 employees, the lab is helping to shape the national program in inertial fusion energy.

Karen Clark founded the first catastrophe modeling company in 1987 and, in doing so, created an industry. She continues to release new models to help businesses, insurers and policymakers in 50 countries keep up with the escalating perils of hurricanes, earthquakes, wildfires and other threats. In a property database update released in March 2025, Clark said her technology maps some $100 trillion in total risk exposure (accounting for post-disaster construction costs and population growth) in the U.S. alone. “What are the chances of a $1 billion versus a $10 billion hurricane loss?” Clark recently told the Insurance Information Institute. “You need probabilities so you can evaluate how likely you are to have a solvency-impairing event and how much reinsurance you want to purchase.”

Connie Lehman
63 | Founder, Clairity
Connie Lehman is one of the nation’s foremost experts on breast MRI, mammography and ultrasound, but wanted to give women a tool to better predict their risk for breast cancer. Most of the women diagnosed with breast cancer have no family history and nearly half have no identifiable risk factors. This spring, the U.S. Food and Drug Administration granted de novo authorization to Clairity Breast, the first AI-powered platform that predicts the risk of developing breast cancer over the next five years using only a standard mammogram. The technology reveals subtle patterns in routine images invisible to the human eye. Clairity plans to begin rolling out the tech to care providers this year.

Invasive species cause billions of dollars in economic and environmental damage each year, and there are few solutions that don’t have other environmental consequences, says Pamela Marrone, whose nature-based products earned her induction this year to the National Inventors Hall of Fame. After starting and leading three bio-ag companies and selling them to larger entities, including Bayer CropScience, Marrone’s latest venture focuses on six major invasive species groups, including zebra mussels and toxic algae, both of which damage our water ecosystems.
Svetlana Mojsov
77 | Research Associate Professor, The Rockefeller University
Svetlana Mojsov’s discovery of GLP-1 and its role in insulin secretion and blood glucose led to a revolutionary class of medicines—and fueled one of the biggest stories across medicine and culture today as drug companies have leveraged the discovery into the development of Ozempic and Wegovy. The achievement earned her and her collaborators the 2024 Lasker-DeBakey Clinical Medical Research Award, a prize considered “America’s Nobel.” Mojsov initially had to fight to be recognized for her role in the discovery, waging a 10-year battle to have the U.S. Patent and Trademark Office issue corrected patents when her name was left off the original filings.
Monica Molenaar
