Thank you for agreeing to be a program committee (PC) member. As a PC member, you will have a say on what submissions are included in the conference program and be an advocate (champion) for a set of submissions. You will be provided with all the reviews for submissions you are an advocate for, and if there is a lack of agreement from the reviewers, you will be expected to read the submission and make a recommendation.
Note: Members of the Program Committee see unpublished work of other authors. Your professional ethics preclude disclosure to any other party the contents of the submissions you read, or the reviews of those submissions.
