Hi Steven!

First off, thanks so much for making your Jekyll code publicly available and for your blog posts on RMarkdown and Beamer! I've been using your code to get my own site set up.

1. Helping you update your site as you get promoted: in your footer.html file, your position is hard-coded as "Assistant Professor" instead of referencing your job.title in your _config.yml file. I had to change job.title to jobtitle in the _config.yml title, but then you can just throw

<li>{{ site.jobtitle }}</li>

in your footer.html file instead of the hard-coded "Assistant Professor"

2. You might already know this, but using Awesome Icons will help clean up your footer.html file for your social media links as well (source). If you add

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">

to your head.html file, then you can just use the following to render the social media icons

          {% if site.linkedin_username %}
            <li>
              <a href="https://linkedin.com/in/{{ site.linkedin_username }}">
                <i class="fa fa-linkedin" style="color:gray"></i> LinkedIn
              </a>
            </li>
          {% endif %}

I hope that helps and I hope you rise through the ranks quickly! I hope you're having a great semester and thanks again for the great stuff you've posted!
