Please visit http://yanquaniris.wix.com/yanquanchen (archived portfolio) for more of my work prior to joining the Carnegie Mellon University at fall, 2013.
I am maintaining my portfolio site in parallel with my heavy loads of coursework, academic projects, and human-factor research. Prior blogs and development of ideas in the UX field are not migrated to this site, due to time commitment at CMU, and they are only remained on the above-mentioned website. Please understand that the priorities of projects on this site is only for most recent selected work.
Thank you for your understanding!
