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.

More than 20 years ago, while out taking photos in chilly northern Ontario, Canada, Ken Libbrecht (BS ’80), a Caltech professor of physics, noticed enormous snowflakes drifting down all around him. Although that wintry wonderland moment occurred decades ago, one of the snowy specimens Libbrecht photographed that day officially remains the world’s largest documented natural snow crystal, a six-sided beauty that measures about 1 centimeter in size. To this day, Libbrecht’s snow crystal is the largest photographed in nature, though he says there are surely larger ones out there that will eventually supersede his rare find.
Using advanced techniques to study the brain and body at their most fundamental levels, from the neural circuits that control emotion to the individual T cells that respond to viruses and other pathogens, Caltech researchers uncover the principles and rules that explain how and why life works. We asked Marianne “Where do you see the furture of this research?” to which she replied: “In basic science, great discoveries often emerge from asking good questions and being able to “follow your nose.” We live in a time where there have been very exciting advances in scientific technology. I’m hoping to be able to adapt these new techniques to answer important questions in developmental and stem cell biology. Ultimately, these could lead to treatments for developmental disorders.” Across the Institute, more than 100 faculty members from all six academic divisions and the Jet Propulsion Laboratory, are leading investigations with the potential to improve human health. The Institute is committed to creating solutions to some of society’s most difficult health problems.

Caltech has received a transformative $50 million commitment from Trustee Lynn Booth and Life Member Kent Kresa. The gift endows and names the Lynn Booth and Kent Kresa Department of Aerospace, ensuring Caltech's leadership in space science and exploration. The gift will foster high-impact research and cross-disciplinary collaborations, with funding to attract the most talented graduate students and early-career researchers, and recruit and retain world-class faculty. #Caltech #Philanthropy #SpaceScience #Aerospace
