In the late 1980s, Johnson was the first doctor in the Royal Free Hospital to specialise in HIV/AIDS. At the time, she was one of the UK's few dedicated doctors who were trying to understand HIV when one in ten patients at the Royal Free Hospital with HIV died from the condition. She developed a holistic care programme that could accommodate thousands of patients.

In 2005, Johnson was named Professor of Medicine at University College London. Johnson studied the prevalence of HIV/AIDS in women. She set up the UK's first HIV testing clinic for women. She worked with Jane Anderson on creating the BHIVA guidelines on managing women with HIV.

Johnson was medical director of the Royal Free London NHS Foundation Trust and elected Academic Vice President of the Royal College of Physicians in 2015. She served as an advisor for the Channel 4 drama It's a Sin.
