Blogging on my own site

I’ve recently aquired https://www.particlespace.com for my own portfolio. I want to be able to have a blog on my ‘work’ page, however, I don’t want to do all of that jazz in html. I’m a busy student with a Senior thesis as well as looking for a job. Is there an easy way to get a blog integrated onto my website in the ‘work’ section without being transferred to another (templated) weblog site? I want to keep my style and make everything appear to be onsite.
Thanks for your help.
