A forensic geneticist who has worked on the exonerations of seven people will visit Indiana University April 15 to give a public lecture on how DNA is used to free people who have been wrongfully convicted and how informatics is being misused to pervert justice.

Boise State University professor Greg Hampikian, who holds joint appointments in biology and criminal justice, will speak at 3 p.m. in Room 102 of Lindley Hall on the campus of Indiana University in Bloomington. His lecture, “Stay of Execution: Forensic Bioinformatics and the Innocence Movement,” is part of the IU School of Informatics and Computing Colloquium series.

Hampikian is a board member of the Georgia Innocence Project and founder and director of the Idaho Innocence Project.

After his lecture, he’ll sign copies of his book, “Exit to Freedom,” which documents Calvin Johnson’s successful fight to prove his innocence after serving 17 years of a life sentence in a Georgia prison.
