Sonequa Martin-Green has provided some details about her character in Star Trek: Discovery.
According to EW, Burnham is “fully human (not half-Vulcan as some have speculated [including this reporter!]) and is the first human to attend the Vulcan Learning Center as a child and then the Vulcan Science Academy as a young woman. She has a close relationship with Sarek (James Frain), the father of Spock. For the past seven years, she’s been serving on the U.S.S. Shenzhou.”
“I’m the first officer on the U.S.S. Shenzhou that is captained by Captain Philippa Georgiou, who is played by the amazing Michelle Yeoh,” said Martin-Green. “I have an inner war and it’s a journey of self discovery and finding out what it means to be alive, to be human, to be a Starfleet officer, what it means to be a hero.
“I have the Vulcan conflict in my life from Sarek and Amanda so there’s always going to be that inner conflict with me. But I think it’s relatable because we all have some kind of inner conflict going on — who we are versus who we present ourselves to be. There’s a lot to be discovered.”
