Protractor - get child element of an element?

Question

I am trying to access child element of an ng-repeat element but I am having troubles doing that.

I have searched around about the problem and the solutions that I have found did not work for me. One of those solutions was to do something like this:

var parent = element(by.repeater(''));
var child = parent.element(by.....);

When I try the child line I cant see the element function on the parent element..

If you see the screenshot above you will see the structure of the code of the page that I am trying to test.

I need to access the alt attribute of the image of the avatar and get its value (thats the Username of the User).

One thing that came to my mind is to use .getInnerHTML() on the ng-repeat row which will return a string with all that code. From there I can find the alt attribute and its value with string manipulation but this seems too brute and I am sure that there has to be a better way.

Simply I want to be able to get row 4 from the repeater and get the Username of the user at row 4, that's all I wanna do actually.
