​Jen Doleac, assistant professor of public policy and economics and director of Justice Tech Lab, University of Virginia, will speak about her paper, "The Effects of DNA Databases on the Deterrence and Detection of Offenders" in a free, public lecture at 4 p.m. Wednesday, April 4, 2018 in ARH, Room 124.

The paper studies how collecting offender DNA profiles affects offenders’ later recidivism and likelihood of getting caught by exploiting a large expansion of Denmark’s DNA database.

In the study, she says, they found "that DNA profiling increases detection probability and reduces recidivism within the following year by as much as 43%" and says the results imply that a 1% higher detection probability reduces crime by more than 2%. "We also find that DNA profiling changes non-criminal behavior: profiled offenders are more likely to engage in a stable relationship, and live with their children," she adds.

Doleac’s visit is sponsored by the Department of Economics. All are welcome.

Refreshments will be served.


Grinnell College welcomes the participation of people with disabilities. Accommodation requests may be made to Conference Operations.

The College welcomes the presence of minors at all age-appropriate public events and for informal visits, with the understanding that a parent, legal guardian, or other responsible adult assumes full responsibility for their child’s safety and behavior during such visits or events. In these cases, the College expects that an adult responsible for the visiting child takes measures to ensure the child’s safety and sees that the child complies with directions of College personnel. Grinnell College is not responsible for supervision of minors on campus.
