Bio:

Dr. Paola A. Prada-Tiedemann received her Ph.D. in Chemistry with a forensic science concentration from Florida International University in 2010. She was awarded the 2010 Intelligence Community (IC) Postdoctoral Research Fellowship funded by the Office of the Director of National Intelligence. Her postdoctoral studies have united interdisciplinary areas such as chemistry, animal behavior and national security to address issues critical to effective intelligence and defense capabilities. She has worked extensively on developing instrumental methods for human odor identification for criminal investigations. She has also worked with canine scent detection in the context of optimizing odor collection techniques for scent training purposes. Her research interests include the evaluation of human odor volatiles as a forensic discriminatory tool as well as the testing of target odor analytes from various specimens of forensic importance for optimal performance of biological detector systems (i.e. canines). She has worked with both national and international police/government agencies to help develop better instrumental and training techniques in various areas of odor detection. She is the author or co-author of numerous journal publications, book chapters, and one book dedicated entirely on human scent evidence. She has presented her research at various national and international forums. She is a member of the American Chemical Society and the American Academy of Forensic Sciences.
