It's the famous Amazon adventure explorer, ex Army Airborne Ranger: Richard Fowler

He'll be speaking about "Among the Mates" with emphasis on their incredible medicine taken from the Phylomedusa Bi-Color" frog, nicknamed "frog sweat" and "sappho". He has a pre-conference program for one week and a post conference program as well, taking his passengers to the Matses to experience their life in the jungle and partake in ceremonies with "sappho". Photo is of a Matses indigenous recovering the "sweat" from one of the frogs. Following this ceremony, the frog is released back into the jungle.
