Hi, welcome :) You are the visitor, and this page had been viewed for times since 06.02.2021.

• 🔭 My research combines HCI, computer graphics, and machine learning.
• 📖 I have partial interests in system programming, mathematics, industrial design, and science history.
• 🌱 I am also an open source fancier in Go, C++, JavaScript, Python, etc. Feel free to check my open source contributions on GitHub.
• 💭 I founded the golang.design initiaitive, and organize it in my spare time.
• 🏠 You can find my resume and talks at my homepage changkun.de.

News

• 01.02.2021: Tutor in CG1: If you have strong interests on programming fundamental computer graphics principles, and would like to apply your knowledge to support other students, please drop me a message before the end of the month! It would also be good (but not mandatory) if you already attended the lecture yourself. Contact: changkun.ou@ifi.lmu.de
