Lecturer will discuss procedures for resolving DNA mixtures

The interpretation of mixtures of DNA from different individuals has been the subject of scientific and legal controversy at least since the murder trial of O.J. Simpson in 1995. This summer, in rejecting the claim that the U.S. Constitution gave an Alaska prisoner the right to retest DNA located at the scene of a brutal rape, Justices of the Supreme Court referred to it as a potential problem in post-conviction DNA testing.

On Friday, Oct. 23, Mark Perlin will deliver a public lecture titled "Three DNA Match Scores, One Verdict," in which he will discuss statistical procedures for resolving DNA mixtures and for presenting the results, as informed by his experience as an expert witness in a criminal case in Pennsylvania. The lecture will begin at 1:10 p.m. in room 112 of the Lewis Katz Building on Penn State's University Park campus (and simulcast to room 119 of the Advantica Building, Carlisle, Pa.).

As a senior research computer scientist at Carnegie Mellon University and the CEO of Cybergenetics, Perlin develops biomedical information and automation technologies. He has invented new statistical procedures in computational genetics and has applied these to mapping human chromosome 11, to analyzing DNA data from the remains recovered at the World Trade Center mass disaster, and to the interpretation of DNA mixtures in criminal cases.
