Christine A. Chaisson, Ph.D., Secretary-Treasurer


Dr. Christine F. Chaisson is a Director in The LifeLine Group™ and a senior member of the LifeLine Group's management team. She is one of three key architects of the new generation of exposure assessment models addressing aggregate and cumulative risk concepts, called LifeLineT. Her special focus on these models has been in the dietary sections-agriculture, food technology, food consumption and food composition. Dr. Chaisson earned a doctorate from George Washington University. She began her career in risk assessment in the US Environmental Protection Agency in the Office of Pesticides and Toxic Substances. At EPA Dr. Chaisson designed and created the first dietary exposure assessment model. She was also the liaison to international regulatory agencies such as AID and WHO. In 1985, Dr. Chaisson co-founded Technical Assessment Systems (TAS), which became the premier exposure/risk assessment consulting firm internationally. Through TAS, she introduced concepts such as population subgroup specificity, better definition of residues in forms of foods and sources of drinking water, use of human activity patterns and actual chemical usage patterns for more accuracy and relevance in risk assessment models. Through these experiences, Dr. Chaisson has become well versed in the expectations of regulators in the US, UK, Canada, Germany and European Union.

Over the past five years, Dr. Chaisson has collaborated with colleagues to create the most advanced exposure and risk assessment software for considering multiple sources of exposure from one or multiple chemicals over the lifetime (aggregate and cumulative assessment). This model, LifeLineT, is now in use in the US and Canada for pesticide regulatory risk assessment, as well as in a dozen universities as a tool for teaching risk assessment.

The LifeLineT models' architecture are readily customized for specialty applications such as providing individual-specific exposure metrics to pharmacokinetic and pharmacodynamic models which better reflect actual dose/effect relationships. Human physiological and morphometric parameters useful as a component of such models were developed by The LifeLine Group™ as part of a research project with the American Chemical Council. Other important projects include the careful examination of nutrition studies and food intake studies to better understand the relationships between dietary profiles (or other personal habits) and health status, especially obesity.

Dr. Chaisson is a Councillor in the International Society of Exposure Assessment, a member of Society of Risk Assessment, the United Agribusiness League and the Institute of Food Technologists. She also serves on the National Council for Arts and Sciences of the George Washington University and the Dean's Advisory Board for the GWU Graduate School of Political Management. She is an advisor to Food Quality magazine. She has published extensively in the fields of exposure and risk assessment.

Eric Mathis, M Sc

email: emathis@thelifelinegroup.org

Mr. Eric T. Mathis is a Product Engineer with The LifeLine Group™ where he participates in a team that is continuing the development of the Lifeline model in C++ and the Visual Studio 2010 C# development platform. Lifeline is a software tool used to determine aggregate and cumulative exposures from pesticide and non-pesticide use. It is based on a form of Monte Carlo analysis called Microexposure Event Analysis. Mr. Mathis has a Master of Science degree from the University of Alabama Tuscaloosa, Alabama in Geography in which his concentration was on Geographic Information Systems. He got his B Sc from Samford University, Birmingham, Alabama.

While working at AMEC Earth and Environmental, Portland, Maine he developed the PhRMA Risk Model using C++. It allows representatives of the PhRMA companies to input their chemical data, and the model then will track the chemical as it flows along a watershed. It will measure exposure along multiple pathways and produce usable output of watershed segment concentrations, drinking water source concentrations, and allowable doses (PNEC) for multiple receptors. He also developed a two-dimensional microexposure event model for General Electric and participated in a team that refined the Microexposure Event Model (MEE) for performing probabilistic risk assessments from the ingestion of fish from contaminated water bodies. The model concurrently quantifies uncertainty and variability in the risk estimates. The current model version was developed using the Visual C++ platform, and uses MS-Access files to store input and output data. This MEE has also been modified for the Penobscot River in central Maine and Fox River in Wisconsin.

Mr. Mathis has experience as a Principal Software Engineer through his work at Allenbrook, in Portland, Maine where he is part of a team that develops policy processing web services for the insurance industry. He also assisted in the development of an insurance rating system that converts insurance business rates into C# code. Mr. Mathis has extensive experience in the use of the C++ development language as well as the Microsoft .Net Framework™.

Douglas Tedder, B Sc

email: dtedder@thelifelinegroup.org

Mr. Douglas R. Tedder is a Product Engineer with The LifeLine Group™ and is an integral part of a development team engaged in the support and enhancement of the LifeLine Model. He has a Bachelor of Science Management Information Systems with a computer science minor from The Florida State University, Tallahassee, FL.

Through his work at AMEC Earth and Environmental in Portland, ME, he gained experience in design and development of an application to model the concentration of chemicals within a watershed. The model tracks the chemical loading of river systems from POTWs, the transport of chemicals through segments of the river system based on GIS data, and evaluates the concentration both at DWS intake and post-DWS processing. The model includes flexible mechanisms for adding loss terms at the POTW, in stream, and DWS intake. Risks are evaluated based on comparisons of the chemical data provided to the calculated concentrations for both water intake and fish concentrations. Flexible output mechanisms, including reports and graphs allow the user easy access to the results of the analysis. The model was developed in Microsoft Visual C++ using Microsoft Access for data storage.

He has also participated in a team to develop a two-dimensional micro-exposure event model for performing probabilistic risk assessments from the ingestion of fish from contaminated water bodies. The model concurrently quantifies uncertainty and variability in the risk estimates. The model was designed for use by GE on the Hudson River, but was purposely created to be flexible and extendible. It has subsequently been used to model both the Fox River for the Fox River Group and the Penobscot River on behalf of Mallinkrodt with little modification required. The model was built using Microsoft Visual C++ using Microsoft Access for data storage.

Mr. Tedder has experience as a Product Architect and has managed a team of developers tasked with responding to critical issues for over 50 clients. Critical issues were defined as those that impeded the client's ability to conduct business. This included changes to any and all aspects of the program as well as extensive work with data manipulation on Oracle and SQL Server databases. He has developed web-based solutions based on XML, HTML, and back-end COM objects. Mr. Tedder is a Microsoft Certified Solution Developer with expertise in Windows Open Systems and Services Architecture (OLE, ODBC), C++, C# .Net, Microsoft Visual Basic, Microsoft Access and he is a Microsoft Certified Professional with expertise in Analyzing Requirements and Defining Solution Architectures.
