Kathleen Poortinga, MPH, Epidemiologist
Kathleen Poortinga is an epidemiologist with an interdisciplinary background in environmental sciences and epidemiology.  She is also a data enthusiast with advanced skills in data management and analysis using tools such as SAS, R, Microsoft Access, and Excel.  Ms. Poortinga manages and provides key technical direction on a variety of health assessment projects, including survey design, health impact assessment, and the statistical analysis of health data.

At Intrinsik, Ms. Poortinga has conducted a number of systematic reviews and meta-analyses on occupational and environmental health issues.  Systematic review projects include a meta-analysis to determine whether employment as a firefighter is associated with an increased risk of chronic obstructive pulmonary disease, and a meta-analysis of nitrogen dioxide inhalation studies to determine a NO2 exposure that causes health impacts in a healthy worker population.  Ms. Poortinga’s epidemiology experience also includes conducting several cross-sectional analyses utilizing data on the occurrence of drinking water contaminants, including: studying the association between fluoride in drinking water and the prevalence of dental fluorosis, and examining the association between exposure to lead in drinking water and measures of environmental justice.  She completed an epidemiological study on the acceptance of HIV screening among adolescents in Washington, D.C. for the National Children’s Medical Center.    At Intrinsik, Kathleen also completes human health and ecological risk assessments, and has used computer programming skills to develop automated processes for performing risk calculations.
Kathleen received her BS in Mathematics with a minor in Art History from Vanderbilt University, then pursued her Master’s in Public Health with a specialization in Epidemiology from George Washington University.

Dr. Glenn Ferguson, Vice President and Senior Scientist

Christine Moore, Senior Scientist
Ms. Moore has over 20 years’ experience in the fields of toxicology and risk assessment and is a Senior Scientist in Eastern Canada. Over the past eight years she has overseen multiple high profile community-based human and ecological risk assessments of metals contaminated sites and areas potentially affected by airborne industrial emissions.  In addition to the assessments of legacy issues associated with historic industrial operations, Ms. Moore has extensive experience in characterizing ecological and human health risks associated with proposed new facilities, through the Environmental Impact Assessment process. Ms. Moore also conducts studies in the occupational health area, focusing on toxicological reviews of various substances, as well as the development of a risk ranking system for worker exposures.  Over the past 20 years her work has included evaluations of a variety of different substances, including criteria air contaminants, metals in the environment, chlorinated dioxins and furans, petroleum hydrocarbons and volatile organic compounds.  Ms. Moore has also provided extensive support to legal counsel on environmental issues related to historic contamination cases.  Much of her project work has involved extensive public consultation, development of public consultation strategies and plans with respect to communicating complex scientific issues to communities.

Intrinsik's Occupational and Environmental Medicine Group is supported by more than 60 scientific professionals, including biologists, toxicologist, epidemiologists, statisticians, and exposure modellers, as well as our network of associates which can provide project support where very specialized skills and expertise are needed.
