[1] In February 2012 Knight was one of the first academics to secure an National Institute for Health Research Professorship, with which she studied maternal morbidity and best practise to care for infants who require early surgery.
[7] Of all the maternal suicides between 2009 and 2013, Knight showed that only 15% had contact with perinatal mental health services, despite over half of the women having suffered from depression before taking their own lives.
[8] Knight investigated the effectiveness of antibiotic prophylaxis to prevent maternal infection following operative vaginal delivery in a randomised controlled trial of 27 obstetric units.
[9] She showed that women who received a single dose of an antibiotic prophylaxis 3 hours after operative vaginal delivery were considerably less likely to suffer from maternal infection.
[9][10] During the COVID-19 pandemic Knight studied the characteristics and medical outcomes of pregnant women who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
