By far, the most popular, memorable and informative session at this conference! Ironically, “Kill the Expert” is also the most lively session. How does it work? We ask the experts to address a common simple question about mitochondria research methodology, such as their recommended way to quantify mitophagy or mitochondrial architecture, and we hope to get a simple answer. You will be surprised how difficult this task is, for the moderator. For the risk of being killed by the expert, we have 2 moderators in parallel. Although most experts swear they will never volunteer to step on that stage ever again, they keep on coming back.
