Dr. Allison Felker BSc (Hons), PhD

Senior Researcher - MBRRACE-UK


Allison joined the NPEU in April 2023 as a researcher for MBRRACE-UK. Allison received her PhD in Reproductive Biology from Queen's University (Canada) and BSc (Hons) in Biomedical Sciences from the University of Waterloo (Canada).

Prior to joining NPEU, Allison worked at McMaster University (Canada) as a postdoctoral researcher and at the Society of Obstetricians and Gynaecologists of Canada (SOGC), where she conducted evidence reviews and contributed to public health projects including those related to perinatal mental health, substance use in pregnancy, and maternal mortality.
