A
header image / text would help... my initial thoughts would be your name long,
spaced out (and not too large) and centered, then immediately under it, in a strong technical - looking font, your words, «A brain Scientist's take on» on the left, leading to «Creative Writing» on the right, but done in a fun «creative» font.
(Note: if you want to free up a little
space in the sidebar, you could probably put the links to your pages across the top of your blog, just above or below the
header image.)
