Joseph has created a basic template that can be set up as a personal website for an academic -- graduate student, postdoc, faculty.
To use it, choose to browse the Template Gallery when creating your site.
In the search box, search for "Academic Research website for Individual Person – Graduate/PhD Student / Postdoc / Research Scientist / Faculty." It should be the second result, and if you click on it, you should see Joseph Williams listed as the author.
