Create a Query based on Incident Management - Resolution. Add the Creation Date but choose the one under Incident and not the Resolution Creation Date. Once added turn sort order (Sort order tab on the attribute properties) on and descending order. In the criteria section add the Incident - Created By user and set condition to "is Current User". You know everything with a resolution should be closed but to make sure something wasn't re-opened you can check the Incident.Status.Title and set the Condition to "Is one of" and add resolved and closed. You might need to add others depending on your process.
Save the query and add it to your dashboard.
