A pioneer at the intersection of hardware, neuroscience and human potential, Mary Lou Jepsen has spent her career turning ambitious ideas into world-changing technology.
Mary Lou Jepsen is widely regarded as one of the most influential technologists of her generation, known for pushing the boundaries of display technology, virtual reality, and neurotech. An engineer, inventor and entrepreneur, Jepsen’s work consistently centres on a powerful idea: technology should fundamentally improve human life, not just productivity.
From Displays to Disruption
Jepsen first rose to global prominence as the co-founder and Chief Technology Officer of One Laptop Per Child (OLPC), where she led the design of ultra-low-power displays that made affordable computing possible for millions of children in developing countries. The initiative redefined how engineers thought about cost, energy efficiency and accessibility in hardware design.
Her breakthroughs in display technology later caught the attention of Silicon Valley’s most secretive innovation labs.
A Force Inside Google X and Meta
Jepsen went on to become a founding executive at Google X, the company’s moonshot factory, where she worked on advanced display systems and experimental hardware. She later joined Meta (then Facebook) as the Head of Display Technology for Oculus, playing a critical role in shaping next-generation virtual and augmented reality experiences.
Her work laid the technical groundwork for immersive computing — a field that now underpins everything from gaming and entertainment to education and enterprise collaboration.
Turning to the Human Brain
In a bold pivot, Jepsen shifted her focus from screens to the human mind. She founded Openwater, a neurotechnology company developing wearable devices capable of imaging and stimulating the brain using light and ultrasound. The goal: to diagnose and treat neurological conditions such as Alzheimer’s, depression, anxiety and brain injuries — non-invasively and at scale.
Openwater’s technology has drawn attention for its potential to democratise medical imaging, bringing capabilities traditionally reserved for expensive hospital equipment into portable, consumer-friendly devices.
A Technologist with a Human Mission
Beyond patents and prototypes, Jepsen is recognised for her deeply human approach to innovation. A cancer survivor herself, she has been vocal about using technology to extend and improve quality of life, not merely to disrupt markets.
Her career stands as a blueprint for purpose-driven innovation — blending hard science, ethical responsibility and social impact.
