My challenge was to efficiently communicate a story about a game to map the brain in only 8 minutes without boring the audience with too many technical details. Working with Sander made my presentation sound natural and unmemorized. His style is friendly, outgoing, precise and he gives you good constructive criticism. My talk at TEDxNijmegen sounded more natural and I think the overall communication improved.
Sander was able to ask targeted, insightful, and compelling questions during our session that helped me see the perspectives that I was missing. Being able to meet him in person was the icing on the cake, as he has the ability to look into your eyes in a way that dispels the anxiety and allows the speaker to shine.
