I have 40 years of experience, and specialize in the field of law and social science with specific knowledge in the areas of evidence law, sociology and social science methods. I have published on such topics as juries, social science and the law and courts and statistics. I have testified on affirmative action and deterrence. Thus I combine not just a sociology Ph.D. and a J.D., but extensive experience in the academy as well as in two quite different government agencies, one more concerned with identifying the best science and the other more concerned with how scientific research will advance high stakes operations.
