Julie Jonas completed her undergraduate and law degrees at the University of Minnesota. After law school, she practiced for eight years with the Ramsey County Public Defender’s Office, where she handled a large caseload, representing clients in felony and misdemeanor cases.

She is currently the Legal Director for the Innocence Project of Minnesota, where she has worked since 2003. In her capacity she directs the screening, investigation and litigation of all IPMN cases. She also works on critical criminal justice policy issues. Her work was instrumental in Minnesota’s passage of its 2014 Imprisonment and Exoneration Remedies Act awarding compensation to innocent Minnesota exonerees.

In addition to her work for the Project, Julie teaches at all of the Minnesota law schools, focusing on the prevention of wrongful convictions and working with clinical students to reinvestigate cases of potential innocence.
