Dr. Fordyce has over 22 years of experience with research protocols and procedures, study design and execution, statistical analyses, database development, and data collection and management.
Dr. Fordyce has experience conducting occupational health and safety studies, including cohort and case-control studies. She managed all aspects of a large, industry-wide injury surveillance program for more than 10-years. In addition, she has managed and conducted numerous cohort mortality studies since 2007.
Dr. Fordyce has performed epidemiologic evaluations, systematic and critical reviews, evaluation of healthcare resource utilization, and reviewed treatment patterns and adverse events of various diseases. Dr. Fordyce also has extensive experience in researching traffic safety issues, including the evaluation of passenger vehicle field performance, post-collision fires, safety belt usage, motorcycle lane-splitting, and airbag effectiveness. Dr. Fordyce has experience evaluating the human health effects of air pollution. Her work has included researching the occupational epidemiology data and risk factors for lung cancer, mesothelioma, and various non-malignant diseases. She has also worked on numerous projects researching and interpreting scientific literature associated with asbestos and has provided support for testimony and expert witness preparation.
Prior to joining Exponent, Dr. Fordyce was employed as a Social Science Research Assistant II by the University of Michigan Transportation Research Institute, in the Social and Behavioral Analysis division.
