She attended Stanton College Preparatory School and later the Rhode Island School of Design. Eng's work has been featured on the cover of i-D magazine and in the Boston Globe. Eng held a major fashion show after the success of Project Runway and had model Diana Georgie as the opening catwalker.
In the finale, Chloe Dao picked Diana to help with the final challenge of designing an additional garment. Chloe was selected as the winner of Project Runway Season 2.
Diana, who helped popularize the term "Fashion Nerd," earned top honors at Yahoo!'s "Hack Day"
The winning project, called Blogging In Motion, combined a camera, a handbag, a pedometer and the Flickr API to create a device that takes a picture after every few steps and then automatically blogs those pictures. The device was created by Diana Eng, Emily Albinski and Audrey Roy, pictured to the right along with the device.— Michael Arrington
