How to map fields from content type to user Profile I am using a content type named application

There are some fields I like to map to the users profile to use them with panels. 

For example there are fields called:


name -->textfield 
nickman-->textfield 
birthday--> date 
about-->text with summery 
etc


Now I would like to map the content of these fields to the same fields used in the users profile to display the information the users had entered in their applications.

How could I do that? Where to start to find more about field mappings?

Thank you guys and gals!
If you want the content of the fields in application to be saved in the user entity, I can think of a couple of approaches:


Use Rules module to copy the values to the user entity when the application content is saved.
Write a custom module and use hook_node_update() to add the values to the user entity.
