On the 16th of this month I appeared at Maison de la Pierre @ Vers Pont du Gard in Southern France to deliver my talk on vitamin D deficiency as a form of immunodeficiency.
You can now find the unedited PowerPoint presentation online here (the version presented featured a few less slides for brevity).
Video of my talk and those of others should be available shortly [update 21/6/18: videos are appearing on this YouTube playlist. There are more to come as of writing].
You can read my overview of the conference here.
