I am trying to create a header so that it looks like the image below such that the header is not right on top of the first line
However, I played with the dimensions on this MWE and can't seem to get it to work. I am wondering if I may be able to get some insight on how to do this.

\headsepuwing\setlength{\headsep}{<length of your choice>}in your preamble, as also explained here: Setting the space between page header and text blockfullspacepackage. By default it sets the\headsepto 0, because it thinks you have no header (default isplainpage style, which doesn't have a header. By using\usepackage[headings]{fullpage}you specify that it does have headers. It would by itself use the page styleheadings, but you overwrite that withfancyhdr.
