Kai Weixian Lan
Research Engineer, Epic Games
Hi! I’m Kai, a research engineer at Epic Games. My work sits at the intersection of machine learning and computer graphics, with a focus on character animation, motion synthesis and stylization. I’m passionate about designing tools and techniques that are not only powerful but also intuitive and accessible to everyone.
I received my PhD in Computer Science from the University of California, Davis, advised by Julian Panetta and Joseph Teran. During my internship at Epic Games, I was fortunate to be mentored by Daniel Holden. If you’d like to connect or collaborate, feel free to reach out—I’d love to hear from you.
Stylized Motion Generation with Text and Styles
A generative system for realistic human animation from a text description and a short style-reference clip. It learns style directly from the example, without labels, and produces long, smooth, style-consistent (and style-changing) motion. Details available on request.
Anomaly Detection Using Voronoi k-distance
A study of Voronoi partitions and density-based outlier detection using the Voronoi k-distance measure.
The Lattice for Finding Conserved Quantities of Dynamical Systems
A systematic approach to finding conserved quantities of polynomial systems by solving a sequence of linear recurrence equations.
A Survey of Mathematical Cryptography
An overview of the history of cryptography, from the Caesar cipher to modern elliptic curve cryptography.
Wallpaper Groups and the Magic Theorem
A study of the wallpaper groups of plane symmetries and Conway’s magic theorem.
