When Nancy Abu-Bonsrah discovered she had been accepted to train as a brain surgeon at Johns Hopkins School of Medicine, the fact she had made history took a while to sink in.

The 26-year-old from Ghana is the first black woman to join the neurosurgery program at the prestigious US college, where the medical discipline of neurological surgery was founded.

“It’s something I didn’t really think about too much until I opened the envelope and was like, 'woah',” she told The Independent. “Then talking to other people in the department confirmed the suspicion.”

Ms Abu-Bonsrah, who starts her training with four other residents in July, used department office records of past students to double-check, but her older brother had soon told friends and family the news.

“He was so excited, happy and proud,” she said. “And when I came home that day and everything had sank in, I made a small Facebook post.”

The post, with a picture of her acceptance note alongside one of her and her husband, has been liked more than a thousand times.

Ms Abu-Bonsrah said she had moved to the US from Ghana around 11 years ago and studied chemistry and biochemistry at Mount St Mary's University in Maryland.

She then went straight to Johns Hopkins University, also in Maryland, to study medicine.

Her interest in neurosurgery stems from a trip to Ghana she took in her winter break in her junior year of college, to shadow doctors and learn more about the country’s health system, because she hoped to return there to work one day.

“It happened that the physician I shadowed there was a neurosurgeon. I was impressed by his skill, and I was also impressed by his boldness in general,” she said.

“Ususally when I think about brain surgery, I think the brain is sacred and you don't touch it or do anything to it, but to see them do these remarkable surgeries, and have good outcomes was something that impressed me.”

She also noticed how “overwhelmed” the surgeons appeared to be, saying: “There were countless patients that they had to see and there are so few of them.

“I thought it would be nice to combine my interest in this field with an opportunity to provide service back to my country and other countries that don't have as much surgical infrastructure.”

Harvey Cushing founded the speciality of neurosurgery at Johns Hopkins in the early 20th century. Another famous historical brain scientist, Walter Dandy, also worked at the institution.

The college is consistently ranked in the top five medical universities in the world, alongside Harvard University and Oxford and Cambridge.

Before she begins her residency, Ms Abu-Bonsrah said she plans to relax, prepare for the course by reading, and travel to Ghana and to attend a conference in LA.
