He isn't named, so we don't know.
His desk is on the top floor. Keep going until you can go no farther. To enter the building, you need to follow the Falafel delivery at lunch. Go to the Falafel stand, then back to Globochem as he is bringing in their food.
The 35th island (August 2013) will be Virus Hunter Island.
The game saves by itself.
You go out the way you came.
That is not part of the island quest.
In the order that you encounter them, they are: - clerk at fitness center - random character at bus stop - conspiracy theorist on roof (Bert Shell) - PDC pizza truck driver - clerk at video store (secret PDC lab) - doctor in the PDC center (Dr. Lange) - the falafel shop owner/delivery man - patient zero (Joe Stockman)
Just click on the two pieces of mail for Joe Stockman: a postcard about his vacation and a letter from his employer, Globochem. That's all you need to do. To see him at Globochem, go to the Falafel stand (far right) and follow the owner as he makes a lunchtime delivery there.
The exit of the hand is at the upper left.
If you are stuck (cannot click to exit to the stomach), try rebooting Poptropica in your browser. If you are still stuck, try going to Home, then the Store, and get the Haunted House card, which is the only way initially to leave Virus Hunter Island. Several glitches were the result of programming errors that locked up browsers during the first month of the island's appearance.
You look for a piece of mail with the name Joe Stockholm on it.
Well since the last island was Virus Hunter island, the next one will be Poptropilis Games 2013.
The PDC is in the basement of the Green Square video store. Once you have spoken to the conspiracy theorist and brought him the bag of shredded documents, he will give you a fake badge to show to the receptionist at the video store.
