This morning Maureen Shuh, a former post doctoral fellow with David Derse, wrote me to say "It is with great sadness that I inform you that Dr. David Derse passed away last night. He had advanced stage liver cancer which was not diagnosed until several weeks ago at which point it was too late. He did not suffer, and he was surrounded by his family."
David was a valued member of the Retrovirology editorial board; he was an esteemed colleague and a good friend. We will miss David very much. We plan to publish an obituary of David in Retrovirology soon.
