SIUE Segue Radio Show Interview
Dr. Dirks-Linhorst has expertise in the legal/judicial portions of the course work at SIUE, and is the only faculty to hold both a PhD and a law degree. Prior to joining the faculty, she had a distinguished career in law and policy positions. She served as a Missouri Assistant Attorney General for 5 years where, among other dockets, she was responsible for the juvenile court docket appearances for her client, the Missouri Department of Mental Health. She became the Forensic Director at the Missouri Department of Mental Health, serving as the liaison between the 115 counties of Missouri’s judicial system and the Department of Mental Health to assure just outcomes for those defendants arrested and charged with crimes but also being identified with possible mental health issues. She later served as Deputy Director for Policy and Program Development where she was responsible for planning, identification of new policy initiatives (housing, sexual predators, elderly drivers, etc.), and then worked with constituent groups to draft and finalize new policy. Dr. Dirks-Linhorst brought this experience, along with her PhD in Criminology and Criminal Justice, to share with the SIUE students. She developed the Mental Health in the Criminal Justice System course, a Judicial Process course, and a Criminal Procedure course, while sharing her experience in the classroom when teaching Ethics, and the Rehabilitation and Treatment in Corrections. Her dedication to experiential learning opportunities well serves the students as she works with over 130 students per year to obtain internships with criminal justice agencies. Her scholarship and teaching accomplishments led to her being named the William and Margaret Going Endowed Professor for 2013-2014.

SIUE Segue Radio Show Interview
Dr. Oberweis writes and/or teaches in the areas of drug policy, sexual violence, research methods, law and society, and gender in criminal justice. Her teaching style incorporates connections between our policy goals and the various approaches we take to achieve those goals. Every course she teaches takes some issue or topic and brings in actual policies to examine the connections between what want, what we know and what we do in various attempts to control social problems or create a safer citizenry. Her approach is rooted in the connections between knowledge, power and justice. Dr. Oberweis earned her doctorate in the interdisciplinary field of Justice Studies from Arizona State University, and she brings this interdisciplinary background to bear on each of the policy areas she studies.
