This week's guest blogger is Richard Lempert of the Michigan Law School. Professor Lempert is particularly concerned with the problem of applying social science research to legal issues. This is reflected in much of his work, particularly his work on juries, on capital punishment and on the use of statistical and social science evidence by courts, as well as in his service as an original panelist in the National Science Foundation's Law and Social Science Program and with the National Research Council's Committee on Law Enforcement and the Administration of Justice, which he chaired from 1987-89. He is the author (with Joseph Sanders) of An Invitation to Law and Social Science and co-editor (with Jacques Normand and Charles O'Brien) of Under the Influence? Drugs and the American Work Force. From 1982-85, he edited the Law & Society Review. He is a recipient of the Law & Society Association's Harry Kalven Jr. Prize prize for outstanding socio-legal scholarship and has held visiting fellowships at the Center for Advanced Study in the Behavioral Sciences and at the Russell Sage Foundation. In 1993 he was elected a fellow of the American Academy of Arts and Sciences. He currently serves as the secretary of Section K of the American Association for the Advancement of Science.
