Hi, 

there is a tutorial with new custom field type creation:

https://developer.atlassian.com/jiradev/jira-platform/guides/fields/tutorial-creating-a-custom-field-type

The value you want to display can be got using 

ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

 Or you can use Script Runner plugin and its Scripted field which would be easier than to create a new custom field type
