“Opportunities for Safer Chemical Decision Making”

Chemical innovation and commerce has been an integral part of our economic and industrial success; however, ensuring the safety of public and occupational health in view of the many ways we are exposed to these chemicals is hotly debated.  The key American statute in the regulation of chemicals, the U.S. Environmental Protection Agency’s Toxic Substances Control Act of 1976 (TSCA), has been criticized widely for being ineffective in promoting public welfare while being subject to capture by corporate interests.  Whatever one believes about the various critiques of TSCA, its ineffectiveness can hardly be questioned: of 65,000 chemicals existing before the TSCA was passed, only 200 have received partial testing, and 5 have been at least partially regulated.  In commerce today, there are at least 80,000 chemicals.  Clearly, chemicals regulation needs a new approach to avoid gridlock and reduce the cost of regulation, while continuing to encourage innovation and protect public safety.

Dr. Royce Francis of the Department of Engineering Management and Systems Engineering is studying the role of new applications of the regulatory process called alternatives analysis in reforming American chemical regulations. In addition, Dr. Francis is the subgroup leader of an industry-academic partnership hosted by the International Life Sciences Institute (ILSI) Health and Environmental Sciences Initiative (HESI) to study decision making challenges in alternatives analysis, especially its relationship to risk analysis, and ways to explicitly address tradeoffs among risk outcomes attributable to the value judgments encoded in safer chemical selection.  At GW, Dr. Francis is collaborating in this work with Prof. George Gray of the Department of Environmental and Occupational Health in the School of Public Health and Health Services.  Their research will contribute to this ongoing public discussion on such factors as health organizations’ priorities’ impact on promulgated health risk values, and the role of evidence synthesis in supporting “new,” “voluntary,” or “collaborative” approaches to chemical regulation.  (Provided courtesy of Prof. Royce Francis of the Department of Engineering Management and Systems Engineering)

SEAS Entrepreneurship Course: SEAS 6200 - Launching Technology Ventures

The course's purpose is to explore lean startup management practices and learn how to develop a complete business plan. Startups usually fail due to lack of customer demand, not product development problems. These new ventures burn through their capital, wasting money on engineering and marketing before discovering they have built a product no one wants. LTV will explore lean startup practices and focus on the integration of marketing and engineering functions and emphasize MVP (Minimum Viable Product). Register today! For more information, e-mail the instructor, Mr. Richard Stroupe.
