Anna S. Duggar became the full-time Director of the Forensic Chemistry program in the Department of Chemistry in 2010, after having worked in the Department as adjunct faculty starting in 2004. Her research interests include photon and electron microscopy of particulate evidence, false negative results in common tests for hemoglobin, bloodspatter pattern analysis, and the application of science to crime scene practice.
She is a native of New Orleans and a graduate of Benjamin Franklin High School. Before coming to Loyola, she taught at the University of West Florida, Tulane University, and Tulane University City College, and taught at a number of police academies as an FBI-IDC POST-qualified instructor. From 2006 through 2010, she worked as Director of the New Orleans Police Department Crime Laboratory and has worked as a forensic analyst since 2000, first with Office of Chief Medical Examiner, New York City; then in Pensacola, FL, with Florida Department of Law Enforcement; then with New Orleans Police Department Crime Lab and St. Tammany Parish Sheriff’s Office Crime Lab. Her casework has led to the provision of courtroom testimony in Criminal District Court in Orleans Parish and St. Tammany Parish, and in the United States District Court, Eastern District of Louisiana.
She is a member of the American Academy of Forensic Sciences, the International Association for Identification, and the McCrone Research Institute Alumni Association and a Diplomate of the American Board of Criminalistics.
