Annie Dufour was born in Quebec City, Quebec, Canada, on March 14, 1969. She grew up in Stoneham, where she devoted a lot of time to reading mysteries, observing wild life and downhill skiing. She graduated with a BS in biology from l’Université Laval in 1992. Like her fictional protagonist, Benoit Dion, Annie received a Ph.D. in epidemiology with a specialty in infectious diseases (HIV and hepatitis B).

Annie’s first publication was a scientific article titled Prevalence and Risk Behaviours for HIV Infection Among Inmates of a Provincial Prison in Quebec City (AIDS 1996, 10: 1009-1015). She then wrote and co-authored several scientific articles, which appeared in peer-reviewed journals such as AIDS, Journal of Acquired Immune Deficiency Syndromes, Journal of Infectious Diseases, Sexually Transmitted Diseases, American Journal of Public Health and Canadian Journal of Public Health.

During her graduate studies, Annie was a recipient of a NHRDP scholarship (Health Canada), and she won prizes, such as the New Investigator Award (Annual Canadian Conference on HIV Research) and the Excellence Award in Epidemiology (AIDS Research Network of the Fonds de la Recherche en Santé du Québec). She also participated in professional scientific meetings (International Conference on AIDS, International Congress of Sexually Transmitted Diseases), where she presented her research results.

Annie started writing fiction in 1999-2000, and her two French-language mysteries featuring her Nicolas Lajoie and John Hanley characters, Cinq enlèvements, quatre cadavres, trois amours, deux bouledogues et une... (Leméac Éditeur Inc., 2002) and Les enfants de Doodletown (Les éditions de la Courte Échelle inc., 2005) received enthusiastic critical reviews, and earned her an interview on television (Réseau TVA). Her third mystery is in the hands of her publisher.

Annie is married to a researcher in microelectronics, Benoit Dufort, and they live in Westchester County, New York, with their adopted cat, Moumou. Annie devotes her time to writing in French and in English, reading mysteries, cooking, mountain biking, and traveling.

Annie is a member of l'Union des écrivaines et des écrivains québécois (UNEQ), Crime Writers of Canada (CWC), Mystery Writers of America (MWA), Sisters in Crime (SinC) and Sisters in Crime Internet Chapter (SinC-IC).
