Fionna S. Mowat, Ph.D.

Principal Scientist

Exposure Assessment & Dose Reconstruction

Professional Profile


Dr. Mowat is a risk assessment practitioner who specializes in exposure assessment. She has over 10 years of multidisciplinary experience in the fields of ecological and human health risk assessment, primarily focusing on exposure assessment. Dr. Mowat has conducted human health risk assessments for various chemicals, including asbestos, various nanomaterials (e.g., metal oxides, carbon nanotubes), hexavalent chromium, lead, and manganese. Currently, her primary areas of interest are exposure assessment from various chemicals, mineral fibers, and nanoparticles in occupational settings, and evaluating potential exposures resulting from use (and misuse) of consumer products (e.g., mastics/adhesives, phenolic compounds, friction products [i.e., brakes and clutches], jewelry, roofing materials, gaskets, and children’s toys). In particular, Dr. Mowat has been involved in the design, conduct, and publication of exposure simulation tests designed to simulate historical exposures to products that were manufactured and used during a time when no air samples were collected and industrial hygiene data were unavailable. Dr. Mowat also has significant experience in exposure assessment of nanomaterials in occupational settings and in consumer products, with particular focus on mixed metal oxides and carbon nanotubes. Dr. Mowat has performed several reviews of products containing mixed metal oxides, such as personal care items, and has presented a risk assessment framework for assessing exposures to nanomaterials in consumer products. She also recently published a book chapter summarizing the exposure and toxicology studies to aid in evaluation of potential risk of nanomaterials resulting from use of consumer products.

Dr. Mowat had also designed, led, and conducted various pharmacoepidemiologic projects, including analyses of clinical data, claims records, and electronic medical or health records (EMR/EHR); literature review of various diseases and conditions, particularly as they relate to identification of market share; and life-cycle management assessment for various diseases and drugs. As part of this research, Dr. Mowat has performed epidemiologic evaluations of rare bone and blood conditions in various subpopulations, investigated the clinical and economic burden and risk factors associated with various cancer outcomes, evaluated standards of care in breast and ovarian cancer patients, and described the healthcare utilization for different subpopulations. Dr. Mowat summarized this work in written manuscripts and has contributed to epidemiologic and other sections of regulatory documents for use in both the U.S. and Europe.

Dr. Mowat also has experience with chemical and toxicological characterizations of sediment mixtures bioavailability analysis of metals, and interpretation of bioassays. Dr. Mowat is also trained in biomedical engineering.
