John Onuigbo
Masters Student in Education, admitted Autumn 2026
BioJohn Onuigbo is an education innovator and social entrepreneur whose work focuses on helping students in vulnerable communities gain the skills and confidence to thrive in the future workforce, regardless of the limitations of their environment. His mission lies at the intersection of education, entrepreneurship, and technology, where he creates transformative learning opportunities that bridge access and possibility for young people across Nigeria and beyond.
John is the founder and chief executive officer of Foris Labs, a virtual science laboratory that enables secondary school students to perform experiments in physics, chemistry, and biology through interactive digital simulations. Built in response to the limited access to functional laboratories in many Nigerian schools, Foris Labs is redefining how science is taught and experienced. The platform has been adopted by leading schools across the country, helping students understand core scientific concepts and teachers deliver more engaging lessons.
Alongside this, John founded Stemnovo NG, an initiative that empowers young people in rural and semi-urban communities with practical skills in coding, robotics, and entrepreneurship. Since its inception, the program has reached over 17,000 students, providing them with the tools to turn curiosity into innovation. Many participants have gone on to win national and international innovation competitions and develop technology-driven solutions to local challenges.
In recognition of his impact, John became the first African to win the Stanford Center on Longevity Design Challenge in 2021, a global innovation competition that celebrates creative solutions advancing learning, health, and wellbeing. His leadership has also guided students to victories in major programs, including the Diamond Challenge, Beyond School Community Challenge, the World Affairs Challenge, and the UK–Nigeria Debate Championship. He won The Future Awards Africa Prize for Education 2025 and was named a Dalai Lama Fellow for the year 2026.
John served as the youngest member of the South East Development Commission’s Venture Capital Advisory Committee, where he contributed to developing a framework for a $50M VC fund focused on youth-focused innovation and entrepreneurship development across the region. In 2025, he was named a Social Shifters Fellow and appointed to the Social Shifters Global Youth Council, where he works alongside young leaders around the world to promote inclusive and sustainable innovation. -

Colin Ophus
Associate Professor of Materials Science and Engineering and Center Fellow at the Precourt Institute for Energy
BioColin Ophus is an Associate Professor in the Department of Materials Science and Engineering, and the L&S Family Center Fellow in Energy and Sustainability at the Precourt Institute for Energy. He previously worked as a Staff Scientist at the National Center for Electron Microscopy (NCEM), part of the Molecular Foundry, at Lawrence Berkeley Lab. He was awarded a US Department of Energy (DOE) Early Career award in 2018, and the Burton medal from the Microscopy Society of America (MSA) in 2018. His research focuses on experimental methods, reconstruction algorithms, and software codes for simulation, analysis, and instrument design of transmission electron microscopy (TEM) and scanning TEM (STEM).
Colin advocates for open science and his group has developed open-source scientific software including as the quantitative electron microscopy (quantEM) analysis code, the Prismatic STEM simulation code and the py4DSTEM analysis toolkit. He has taught many workshops around the world on topics ranging from scientific visualization to large scale data analysis. He also is the founder and editor-in-chief for a new journal based on interactive science communication named Elemental Microscopy. -
Marily Oppezzo
Senior Research Scholar, Medicine - Med/Stanford Prevention Research Center
BioDr. Oppezzo is an Instructor of Medicine at the Stanford Prevention Research Center and head of the nutrition pillar at Stanford Lifestyle Medicine. She is a behavioral and learning scientist, dietitian, and exercise science interventionist. She earned her PhD in Educational Psychology from Stanford University, and holds a Master’s degree in Nutritional Science, and is board certified Lifestyle Medicine Professional.
Dr. Oppezzo's work combines her extensive training in nutrition, exercise science, and behavioral science to develop innovative interventions that empower individuals to adopt sustainable, healthy habits - integrating them into their already busy lives. With a focus on "minimal dose, maximal gains" she explores the best ways for people to adopt small, actionable changes for significant improvements in health and well-being. She is particularly interested in the impact of "exercise snacks"—short, accessible bouts of physical activity—on productivity, mood, and overall health. One of her key interventions, "Stronger," is designed to provide peri- and post-menopausal women with effective strength training that maximizes benefits while minimizing time commitment. -
