Dr. Burger was a little rusty. He was CEO of several biotechnology companies, some nasdaq listed if I remember correctly for several years. It looked like they asked him to do it last minute, he used their slides and added his name. So fast they haven't even announced him yet. When he talked about GvHD, he got a little more excited, that being his baby from before. It is good to see that he must have simply stepped down before to let RP take the CMO role (and not the other possibilities)
