Laravel 5.1 Auth to get back the username in sesson?

i'm using laravel 5.1, there's method "Auth" can generate the login, register,etc... But i have a question that how to get "that" username back as i wanted?

For example, i Registered as,

email: 123@123.com , name: 123

And in database, i have another table "profile", laravel model : "Profile", which contains:

email: 123@123.com , sex: male

In here, i want to show "male" in the view.

1) How laravel work to find specify data across different table ?

2) Does Laravel has other "word" to represent "this(123@123.com)" when it was logged already(Auth) ?

Thanks!!
