Long before students attended classes or groundbreaking discoveries emerged from campus, more than one million U.S. Marines once trained on the land where UC San Diego now stands. From 1917 to 1964, much of the campus was known as Camp Matthews before the land was transferred to the university - the same year UC San Diego welcomed its first undergraduate class. Today, students and faculty are tackling questions that lead to advances in medicine, technology, climate science and our understanding of the world.

2. Military service is still part of campus life

San Diego's longstanding military presence continues to shape the campus community. More than 2,900 military-connected students call UC San Diego home, including 127 active-duty service members, reservists and National Guard members; 232 student veterans; 2,416 military dependents and 206 military-affiliated graduate students. Through the Student Veterans Resource Center, UC San Diego helps military-connected students navigate campus life, connect with resources and build community while pursuing their degrees.

The impact extends beyond student success. This year, the Rady School of Management launched a partnership with the U.S. Navy's Fleet Readiness Center Southwest to expand leadership development, educational opportunities and workforce readiness while creating new pathways for students to contribute to the nation's defense industrial base.

3. A weather forecast almost changed the course of World War II

D-Day, the Allied invasion of Normandy that changed the course of World War II, was originally planned for June 5, 1944. But a storm in the English Channel forced Allied leaders to reconsider. The decision to delay the invasion by one day relied on wave forecasting research developed by Scripps Institution of Oceanography's Harald Sverdrup and Walter Munk. Their pioneering model helped military planners determine when conditions would allow troops to safely reach the beaches of Normandy and later informed other pivotal World War II operations, including the Battle of Iwo Jima.

4. Discoveries made here are improving patient care nationwide

For decades, UC San Diego scientists and physicians have helped transform the way diseases are diagnosed and treated. In the 1990s, UC San Diego helped lead the clinical trials that produced the first FDA-approved treatment for ischemic stroke - a breakthrough based on pioneering research by Justin Zivin that remains the standard of care today. Chemist Roger Tsien's Nobel Prize-winning work on green fluorescent proteins also revolutionized biomedical research, giving scientists an unprecedented window into living cells and accelerating discoveries in fields from genetics to cancer research.

That legacy continues today. Scientists Ludmil Alexandrov and Scott Lippman are using artificial intelligence to deliver faster, more accurate cancer diagnoses, while surgeon-scientist Quyen Nguyen is building on Tsien's discoveries to develop fluorescent imaging technology that helps surgeons see - and avoid - critical nerves during delicate procedures. Across UC San Diego Health, approximately 1,800 clinical trials each year bring promising new therapies to patients while advancing the future of medicine.

5. Some of the world's most important climate records began at UC San Diego

Understanding our planet begins with good data. Some of the world's most important environmental records trace back to our campus, where scientists have spent decades measuring Earth's atmosphere and oceans with remarkable precision. At Scripps Institution of Oceanography, Charles David Keeling began what would become the Keeling Curve, the world's longest continuous record of atmospheric carbon dioxide. The dataset provided the first clear evidence that CO2 levels were steadily rising and remains a cornerstone of climate science.

UC San Diego has also been home to some of the world's leading climate scientists. Before joining Scripps in 1990, Veerabhadran Ramanathan discovered that chlorofluorocarbons (CFCs) - chemicals once widely used in refrigerators and aerosol sprays - were powerful greenhouse gases that also damaged Earth's protective ozone layer. At Scripps, he expanded that work, investigating replacement chemicals and atmospheric aerosols while continuing to advance our understanding of Earth's changing atmosphere.

Building on decades of discovery, Scripps continues to help the world monitor a changing planet through global ocean observing programs, NASA satellite missions and technologies such as Argo, a fleet of robotic floats that collect real-time data from oceans around the world. Together, these efforts help improve weather forecasts, track changing ocean conditions and deepen scientists' understanding of Earth's interconnected systems.

6. Tomorrow's technologies are taking shape on campus

From artificial intelligence to next-generation microelectronics, engineers and computer scientists are helping develop technologies that will shape how we live, work and connect in the decades ahead. Long before ChatGPT became a household name, visiting scholar and Nobel Prize-winning AI pioneer Geoffrey Hinton collaborated with UC San Diego researchers to develop today's neural networks. Among those collaborators was the late Jeff Elman, former dean of the School of Social Sciences, whose work on language, learning and cognition helped lay the foundation for large language models that now power generative AI chatbots.

The campus has also helped shape the digital infrastructure that connects the world. Internet pioneer Hans-Werner Braun, later a leader at the San Diego Supercomputer Center, played a key role in the development of the National Science Foundation Network (NSFNET) - the high-speed academic research network that became the backbone of the modern internet. More recently, UC San Diego has helped strengthen domestic semiconductor innovation through the Department of Defense-backed Microelectronics Commons, advancing new chip technologies for applications ranging from autonomous vehicles to aerospace.

Those breakthroughs don't stay in the laboratory. Through one of the nation's most active innovation ecosystems, the campus has launched more than 1,000 startups and executed more than 2,300 licensing agreements, helping move innovations from the lab into the marketplace and fueling economic growth and job creation.

7. Our research is helping communities prepare for disasters

Preparing for disasters starts long before they strike. At UC San Diego, engineers and scientists are developing tools that help communities withstand earthquakes, wildfires and other natural hazards. Our outdoor shake table - the only facility of its kind capable of testing full-scale structures under realistic earthquake conditions - has helped shape building codes and construction practices, making homes, hospitals and other critical infrastructure safer. High-performance computing resources at the San Diego Supercomputer Center also help researchers worldwide model hurricanes, earthquakes and other hazards before they occur, improving preparedness and emergency planning.

When disaster strikes, technology developed on campus helps emergency managers respond more quickly. The ALERTCalifornia network's more than 1,200 high-definition cameras and the WIFIRE program's AI-powered fire simulations provide real-time information used to monitor wildfires, plan evacuations and protect communities across California and beyond.

8. UC San Diego research is helping feed the nation

A healthy food system depends on more than what's grown in the field. Here, scientists are developing solutions that strengthen agriculture, support farmers and improve access to nutritious food. In the School of Biological Sciences, researchers have developed an immune-priming approach that helps honey bees resist disease, protecting pollinators responsible for crops that feed millions of people. They also uncovered the genetic basis for shatter-resistant canola, an innovation that helps farmers increase yields while using less land and water.

Beyond the farm, researchers are applying artificial intelligence and data science to improve food access. The NOURISH platform helps communities identify opportunities for fresh food markets, connect small business owners with resources and expand access to nutritious, affordable food in underserved neighborhoods.

9. The next chapter is already being written

Every breakthrough begins with someone willing to ask a bold question. As the nation'sNo. 1 public college for research, UC San Diego is preparing the next generation of scientists, engineers, physicians, entrepreneurs and public servants to tackle challenges that haven't yet been solved.

That preparation extends far beyond the classroom. Through hands-on research, entrepreneurship and initiatives like The FORGE, students work alongside faculty, industry and government partners to translate ideas into real-world solutions. Launched in 2026, the FORGE creates pathways for students, researchers and startups to develop dual-use technologies that strengthen both civilian life and national security while preparing an innovation workforce for the future. UC San Diego alumni have gone on to become NASA astronauts, lead groundbreaking discoveries and launch companies that improve lives around the world. America's story is still being written - and UC San Diego is helping prepare the people who will write its next chapter.
