She joined the Boalt faculty in 2011 after a tenure as a Thomas Grey Fellow at Stanford Law School. Before Stanford, she worked for over eight years as a trial and appellate attorney at the Public Defender Service for the District of Columbia (PDS). At PDS she was a founding member of a Forensic Practice Group, which studied and litigated forensic DNA typing. She has lectured nationally on forensic science-related issues. She is also a member of the Constitution Project’s National Committee on DNA Collection and is an affiliate of the National Institute of Standards and Technology’s Organization of Scientific Area Committees (OSAC) for forensic science. Her research focuses on the use of forensic science in criminal trials, the continuing viability of the lay jury, and the ways in which concepts of criminal procedure and evidentiary law must be re-theorized in an era of science-based prosecutions.
