ABOUT ICSI

The International Computer Science Institute (ICSI) is an independent non-profit research institute in the heart of Berkeley, California. ICSI is a place where researchers solve hard problems and help change the world. We pioneer interdisciplinary research across all areas of computer science and data science to generate fundamental insights, address societal challenges, and catalyze entrepreneurial opportunity. 

We foster a uniquely flexible and collaborative intellectual environment.

• It’s about big ideas. ICSI is a place for taking on daunting challenges—not “playing it safe.” Our researchers pursue questions they feel are in the public interest and advance technologies that address important societal needs. This transformative work often spans disciplines, sectors, and borders.
• It’s about solving problems, not submitting papers. Unlike industry or academia, ICSI does not have strict expectations on research output. We may write traditional research papers, but we also release software, curate datasets, build research communities, and spin out startup companies. Our researchers leverage strong ties with UC Berkeley and the Silicon Valley ecosystem to bring great ideas to fruition in whatever way is best suited to the problem at hand.
• It’s about inclusion. Visitors come from all over the world to pursue research at ICSI. We’ve hosted scientists and more than 620 postdocs from Germany, Spain, Switzerland, Finland, Italy, the United Kingdom, Holland, Israel, China, Japan, Singapore, the Philippines, Brazil, Canada, and more. We believe diverse perspectives create the best ideas.

We are looking for equity-minded applicants who demonstrate a sensitivity to and understanding of the diverse academic, socioeconomic, cultural, disability, gender identity, sexual orientation, and ethnic backgrounds present in our community. When you join the team at ICSI, you can expect to be part of an inclusive, innovative and equity-focused community that requires broad collaboration among staff, students and community partners.
