Ellen Yi-Luen Do is a PhD alumna from the College of Architecture at Georgia Institute of Technology. She did her undergraduate design thesis with Ming-Hung Wang at National Cheng-Kung University in Taiwan (Honors), R.O.C. and did graduate work with William J. Mitchell at the Harvard Graduate School of Design, before joining the PhD program at Georgia Tech. She has taken a number of courses from College of Computing, and gotten interested in the issues of Human Computer Interaction taught by James D. Foley, and done usability studies at the Graphics, Visualization & Usability Center. In addition to the Electronic Cocktail Napkin, she worked on the ARCHIE, Case Based Design Aid for Archtetctural Design, lead by Janet Kolodner, and Eric Domeshek, and her advisor Craig Zimring. She also taught graduate CAD courses on Alias, an advanced visualization and animation software, for Industrial Design program, and won an Outstanding Teaching Award (College of Architecture, 1994). Her research interests include Cognitive Science, Drawing, Sketching and Diagrams, visual note taking, analogy and creativity....when not hacking innovative design software, Ellen enjoys singing, free hand sketching (of course), buying books, skiing, hiking, taking photographs, travelling (with friends), watching movies, playing tuba, creating origami, eating noodles and sushi.

Ellen taught a week of origami in Mark's Design Theory and Methods class. Paper related workshops from the Spring DTM class are cardboard furniture design and paper clothing fashion show.
