Dear authors and participants, We thank you for your interest in Petra 2020, which is to be held at Corfu Island, Greece, from June 30 to July 3. Your health and safety is our top concern. Our thoughts are with everyone affected by the coronavirus pandemic. Due to the COVID-19 travel restrictions taking place, the organizing committee is currently considering various options for the conference, including offering virtual participation, as well the possibility of postponing the physical conference to a later date, such as late October or early December. We have prepared a survey to get your input and aid us in making a decision. Please respond to this survey before Tuesday, April 7th. Your responses will be reviewed, and we will inform you before the end of April of our decision. We suggest that you please do not book non-refundable tickets to the conference at this time until we provide you with a definitive notice.
