I have been busy speaking lately, and as a result have written a bunch of articles and a lot of powerpoints. I generally upload my powerpoints to my Scribd account, here.
My two most recent presentations were:
Smartphone Applications to Keep your Practice Efficient, your Life Organized, and your Brain Engaged
Social Media, The Discovery Smoking Bullet: The Case of the Big, Yellow Dog
I try to keep my seminars interesting, so I hope you find the slides both engaging and useful. Especially the Social Media presentation.
