I have 35 years of experience, and specialize in the field of health economics with specific knowledge in the areas of costs of illness, injury and death, cost effectiveness analysis, and effects of health on work absences. I have published on such topics as the costs of medical error, the costs and consequences of occupational injury with some emphasis on back pain, the impact of asbestos related disease and death on families, the health care costs of workers’ compensation versus group health insurance, and the first interview study of workers compensation recipients in the United States. I have testified on economic loss due to a death and the economic loss due to wrongful classification of a person as being mentally retarded as a child.
