ACM Computing Reviews is an ACM monthly journal produced in collaboration with Thinkcloud. Reviewer candidates are evaluated and approved based on many criteria, including educational background and professional experience. Every month, one reviewer is selected as Featured Reviewer among a big reviewer pool based on the quality of the reviews. This month, Xinfei is picked! His featured reviewer's profile is displayed on the site for a one-month period. After that period, it is archived and accessible on the site in our Featured Reviewers area. To access his review profile, please go to http://www.computingreviews.com/browse/browse_reviewers.cfm?reviewer_id=123833.
