  1. Served as a statistical consultant in the development of dynamic models for residential property valuation across the United States in order to determine whether certain residential mortgage-backed securities (RMBS) were fairly valued. Made use of statistical and econometric techniques including regression modeling, statistical sampling, bootstrapping, and bias adjustment.
  2. On behalf of a Fortune 100 company, evaluated models that estimated the potential liability in more than 10,000 asbestos settlements. In addition, reviewed the likely bias and other issues with a model that predicted the “propensity to sue” for future claims.  Wrote two expert reports concerning findings and testified as a statistical expert regarding those findings.
  3. On behalf of the New York State Office of Medicaid Inspector General, reviewed the sampling and estimation methodology used to audit Medicaid providers in New York State. Reviewed and critiqued specific methodologies in ongoing matters, and provided recommendations for improving the statistical audit process.
  4. In a series of matters on behalf of the law department for a major city, created and analyzed a massive real estate database, modeled market and sales values, and wrote expert reports to determine potential biases of alternative methods of valuing commercial real estate. Determined the validity of assumptions about lease lengths, turnover rates, and other issues affecting rents and property values. Testified as a statistical expert in one of these matters.
  5. On behalf of the United States Department of Labor, acted as the principal investigator on a study of industry compliance with certain labor laws. Developed and pulled a statistical sample for evaluation.  Performed survival analysis to better understand how long certain industry investigations would last and the likely outcomes of such investigations.
  6. For a major pharmaceutical company, analyzed company and external marketing data to determine the reliability and potential biases in using external data sources. Analyzed physician-specific data for a period of 36 months concerning product marketing to approximately 1 million prescription drug subscribers.
  7. In complex litigation matters involving an undersea oil field, analyzed data from several years of inspections and repairs to determine the likelihood of a catastrophic failure that would result in a major oil spill. Used survival analysis to determine the likelihood of such an event for different inspection and repair cycles.
  8. On behalf of several state public service commissions, directed data analysis and statistical design in a series of tests of Bell South, Verizon, SBC-Ameritech, and Qwest. Beginning in 1998, developed software and procedures for calculating performance metrics and evaluating the competitive environment. Testified before several state public service commissions, including New York, Virginia, Florida, Michigan, and Colorado.
  9. Using social security and insurance company data, developed two probability-based models in order to match unclaimed assets with the individual owners of those assets. The models were successfully implemented at our client, a financial services company, and used to assist state agencies in locating unclaimed assets.
  10. For hedge fund, performing an ongoing series of projects related to pricing risk and return of various investment options. Using standard and proprietary statistical techniques and software, developing models to select appropriate investment funds according to risk and term of the investment.
  11. For the large direct market publisher, improved customer response modeling while reducing the costs of test marketing. Overall test marketing was reduced by combining data for various market segments. This method also increased the precision of the scores assigned to customers concerning their propensities to purchase individual books. These improvements were expected to lead to cost savings and revenue improvement totaling about $1 million annually.
  12. Modeled television audience ratings to determine the Public Broadcasting System’s share of cable royalty distributions. Used statistical methods to determine a reliable estimate of PBS’s cable royalty share.

The work was the focus of intense congressional scrutiny and received a substantial review in the media.
  15. On behalf of Fortune 100 company, created statistical models to determine the probabilities and likely severities of accidents for different employee and accident types. This project resulted in a recommended annual savings of $3 million.
  16. On behalf of the Arava Institute of Environmental Studies, advised on design and sampling methodology for a broad-based survey of environmental education in middle and high schools.
