Caltech

Caltech is a small, collaborative community, where faculty, postdoctoral scholars, students, and staff from diverse backgrounds, cultures, and experiences live, work, and engage with one another. Together, they remain committed to setting the example of what its intertwined missions of research and education can accomplish.

Caltech is an integral part of Pasadena. Together with JPL, we are the city's largest employer and a source of programs that benefit our neighbors: teachers, businesses, families, cultural centers, and government.

What does it take for a robot to be useful in the real world? 🤖 A humanoid robot recently clocked the 100-meter dash in 8.64 seconds—faster than Usain Bolt’s 9.58-second human world record. But some of the robots competing at the same event struggled with stopping safely at the finish line, highlighting a much bigger challenge in robotics. At Caltech, researchers in Aaron Ames’ lab study safety-critical robotics: how to enable autonomous robots to move through complex environments while staying safe around people, walls, obstacles, and the unexpected. The goal isn’t just to make robots faster—it’s to make them capable of navigating the real world reliably. That could eventually mean robots that can safely navigate busy workplaces, assist with physically demanding tasks, operate in environments that are dangerous for humans, or move through everyday spaces alongside us. #AskCaltech

Professor of Astronomy Vikram Ravi answers the question, “What are fast radio bursts?” These extremely bright and energetic flashes of radio waves are thought to come from highly magnetized stellar remnants called magnetars. In a new Nature Astronomy study, Ravi and his team recently demonstrated how FRBs can be used to help study some of the biggest questions about the universe, including the nature of dark energy, dark matter, and ghostly particles called neutrinos.
Did you know that Brian Brophy, Caltech’s director of theater arts, played an iconic character on Star Trek: The Next Generation? Brophy recalls that one of his favorite moments from shooting the episode involved allergies. The soundstage was dusty, he says, and he was sniffling without realizing it. “Right before a take, Patrick Stewart [who played Captain Picard] stood up and said, ‘Will someone please make him stop breathing like that,’” Brophy says. “I looked around, stunned, not sure who he was even talking to—there were about a hundred people on set. If you watch the episode, there’s a moment right after that where I stand up and react—I was taller than him, and in my late twenties, and basically thought, ‘come on, man.’ That moment—being reflexive and aware of the whole situation—was my favorite as an actor. Afterward, in his trailer, Stewart told me, ‘You did a very good job, young man, well done.’ He was genuinely gracious about it.” Happy 60th anniversary Star Trek. The original series premiered on NBC on September 8, 1966. #Caltech #StarTrek

Wildfires don’t all burn the same things, and that matters when it comes to what they leave behind. In a wildland–urban interface (WUI) fire, flames can consume homes, vehicles, wiring, plastics, and other manufactured materials alongside vegetation. That can leave behind contaminants, such as lead and other heavy metals, in ash, dust, and soil that may require professional testing and careful cleanup. Research following the Eaton Fire has helped inform post-fire recovery and policy. In California, lawmakers have passed a bill to establish first-in-the-nation standards and guidance for environmental testing and remediation in homes after a wildfire. Caltech geochemist François Tissot testified in support of the bill, drawing on findings from research his group conducted in the wake of the Eaton fire. The takeaway: After a WUI fire, homes left standing in the burn area still require careful assessment before reoccupation. In California, lawmakers have passed a bill to establish first-in-the-nation standards and guidance for environmental testing and remediation in homes after a wildfire. The legislation now awaits the governor’s signature. #AskCaltech
