Rockstar🎓
Top SchoolYixi Cai is a robotics postdoctoral fellow at KTH’s Digital Futures with eight years of experience bridging academic research and efficient, production-minded code. Holding a PhD in Mechatronics, Robotics, and Automation from The University of Hong Kong and a BE from Beihang, she focuses on how robots perceive and model the world, especially through spatial data structures. Her open-source work includes refactoring and optimizing an incremental k-d tree implementation to remove PCL dependencies, tighten performance, and simplify builds—demonstrating a knack for both core algorithm design and pragmatic engineering. Based in Stockholm, she combines rigorous research with hands-on systems development, favoring lightweight, custom data types for real-time robotic applications.
