Author bio question:

There are so many things that I love about this theme. I particularly love that every post automatically includes an author bio! It's great! If you click on the author's name, it brings you to a list of the author's posts: https://www.nerdempire.org/author/jr-admin/ so I had a couple of issues with this page. 1) So while the all-caps Noto Sans is GREAT for the site subtitle ("A NERD-INTEREST MAGAZINE..." at the top), The Author Bio appears in the header image underneath the author ("J.R. IS A CONNOISSEUR...", and all-caps Noto Sans Bold just doesn't look right for a bio b/c it's text heavy (I think as a general rule, all-caps is not good for anything that's text-heavy). It's a default font-- changing the header fonts in Typography doesn't seem to do anything. I realize that you need to get the pro version to change color schemes and fonts, but I think this one in particular is a bad design choice in general. So... is it possible for me to change the font for author-bio when they appear as post subheadings? Again, I LOVE the Noto Sans All Cap site subtitle, it's just the author bio as a post heading where it's a problem. If I can't change the font, is there a way to disable the author bio on the heading of that page while still retaining the author bio on individual posts? Changing the font would be ideal, but I wouldn't mind if it just had the author name in the heading and not the bio. 2) I chose "JR" as my user name. I am the admin. The URL appears as nerdempire.org/author/jr-admin/ It looks weird to have admin in the URL and I want to take it out (maybe change it to /jr-darewood or even just /jr ) but it's not a post or a page so I can't customize it in wordpress. I'll eventually have other authors too.
