Current projects and partnerships include work with adults and juveniles involved with the criminal justice system. Areas of particular expertise include forensic mental health evaluations, outpatient competency restoration, immigration/asylum issues and forensic neuropsychology.
Our policy and advocacy work focuses on improving forensic mental health systems, ensuring standards for professionals and evaluations, and advocating for legislative reform for marginalized persons. Our accomplished faculty hosts a wide range of forensic psychology expertise. By engaging in research, clinical services and training, we aim to improve forensic mental health practices locally and globally.

Our expertise and experience empower us to provide forensic mental health services throughout Colorado. We lead the way in developing and implementing cutting-edge, evidence-based practices. Services offered include:

- Forensic assessment and evaluation
- Animal cruelty and animal abuse evaluations
- Immigration-related evaluations and interventions
- Neuropsychological screening and assessment
- Brain Injuries Screening Program
Our research interests are broad, but center mostly on the applications of evidence-based practices. Faculty serve in various capacities for national research initiatives as journal editors, journal reviewers, and conference reviewers, and have also authored books and produced other scholarly work outside the traditional academic journal review process. Current projects include:
- Assessing the reliability, validity and quality of forensic mental health evaluations
- Training and certification of forensic mental health evaluators
- Improving decision-making in forensic evaluations
- Supervision and care of persons acquitted by legal insanity
- Exploring the effectiveness of outpatient and jail-based competency restoration interventions
- Evaluating attitudes toward violence risk in mentally ill offenders from relevant disciplines (mental health, judiciary, law enforcement, corrections)
- Examining the effectiveness of screenings and interventions for incarcerated populations with potential traumatic brain injuries
We're a leading source for forensic mental health training, offering various training sessions, workshops and consultations for forensic evaluators and professionals. Our interactive, cutting-edge trainings are tailored to the needs of each individual client. Recent trainings and presentations include:
- Mental health issues in immigration proceedings (Colorado Bar Association / Rocky Mountain Immigrant Advocacy Network)
- Forensic mental health: A review of competency, legal sanity, and violence risk (Federal Public Defense Counsel)
- The College Gateway Program: A model community re-entry program (Colorado Community Development Association)
We also provide consultation on the certification of forensic evaluators.
We offer a postdoctoral fellowship in forensic psychology. The fellowship runs though the academic year (early September through late August) and provides opportunities for practice, research and teaching. Fellows have the opportunity to network with mental health professionals, administrators, judicial personnel, correctional personnel and other justice system professionals around Colorado. The didactic portion of the fellowship is integrated with the forensic psychology fellowship at the Colorado Mental Health Institute - Pueblo and the University of Colorado's forensic psychiatry fellowship program.
The 2024-2025 application is open.
