I was found by Starfleet in 2338 as the sole survivor on Omicron Theta in the rubble of a colony left after an attack from the Crystalline Entity. An artificial intelligence and synthetic life form designed and built by Doctor Noonien Soong in his own likeness. I am a self-aware, sapient, sentient, and anatomically fully functional android who serves as the second officer and chief operations officer aboard the Federation starships USS Enterprise-D and USS Enterprise-E. My positronic brain allows me impressive computational capabilities. However I experienced ongoing difficulties during the early years of my life with understanding various aspects of human behavior and I was unable to feel emotion or understand certain human idiosyncrasies, inspiring me to strive for my own humanity. This goal eventually led to the addition of an "emotion chip", also created by Soong, to my positronic net. Although my endeavor to increase my humanity and desire for human emotional experience is a significant plot point (and source of humor) throughout my live, I consistently show a nuanced sense of wisdom, sensitivity, and curiosity, garnering immense respect from my peers and colleagues.
