Dr. Katherine Pulaski is a fictional medical doctor in the American science fiction television series Star Trek: The Next Generation. She served a rotation as the chief medical officer aboard the Federation starship USS Enterprise-D. During her time on the ship, her medical skills saved the lives of both Captain Jean-Luc Picard and Commander William Riker. She inadvertently caused Geordi LaForge to create a hologram of Professor Moriarty that became self-aware, after a bet involving the abilities of Lt. Commander Data. Pulaski seemed averse to most new technology and preferred to avoid the transporter, but was forced to rely on it to save her own life from a genetically-modified infection. Before arriving on the Enterprise-D, she previously served on the USS Repulse. For a time in her past, she was romantically involved with William Riker's father, Kyle Riker, with whom she has maintained a friendship.
