John R. Hoffman is a Professor of Biology, public speaker and a scientist examining the recovery of the nervous system after injury. Since 2006 he has written several unpublished manuscripts and he is currently working on the first Nathaniel Smythe novel and short story collection. He spends his spare time with his family and running.
