[Theme: twentysixteen] How can I use the single-page bio info on the home page?

On my blog at https://www.yobyot.com, I would like to have the gravatar and links as they appear on a single post page appear in the same position in the sidebar to the left of each post on the home page blogroll.

Just click on any post and then back to the home page to see the difference between the two left sidebar formats

I would appreciate any pointers on how to do this.

Thanks.
