How we review proposals

We review proposals in two stages. The first review will be blind: Reviewers will not see your name or biographical information. They will have access to the title, description and abstract of your proposal. Because of this, please leave identifying information out of these fields.

In a second review, highly-rated proposals will be reviewed together with your personal information. We will evaluate your proposal alongside your past speaking experience and other relevant credentials in order to come up with a balanced schedule. The program committee is committed to selecting a diverse and well-qualified group of speakers.

Reviewers may have questions for you during the reviews. Please reply promptly to help the CFP process move forward.
