Doctor Kuhlman was a doctor who worked at the San Cristobal Medical Facility aboard Sevastopol Station. When a lone Xenomorph was unleashed on the station by the crew of the Anesidora in 2137, he became one of the survivors desperately waiting for rescue. He was encountered by Amanda Ripley when she arrived on Sevastopol to recover the USCSS Nostromo's flight recorder, which had also been brought there by the Anesidora.
Kuhlman was taken by the Alien when it broke into his office behind him as he prepared to leave the medical center.
Eventually, Amanda Ripley, who initially came to the station aboard the Torrens in hope of recovering the flight recorder unit of the USCSS Nostromo, entered San Cristobal to find medical supplies for Torrens crew member Nina Taylor, who was injured boarding the station. Kuhlman helped Ripley find the supplies by guiding her over the intercom, but, shortly after she came back with them, he was killed when he opened a door the Drone was behind.
Terminal logs suggested that Kuhlman was slightly corrupt and had a drug addiction, having given out drugs to several patients who did not need them as well as "self-medicating", according to Dr. Lingard. Due to this, Dr. Morley had locked him out of the despenser. In an audio log by Kuhlman, he claimed his patients needed them and they were suffering, also saying that he did not have a "problem".
