Core Responsibilities

Primary Functions

Design and lead original criminological research projects, defining research questions, hypotheses, study populations, and mixed-methods protocols to produce rigorous and reproducible findings.
Collect, clean, and integrate diverse crime-related datasets (police reports, victimization surveys, corrections records, socio-demographic data, and open-source intelligence) and document data provenance and quality controls.
Apply advanced statistical techniques (regression, time-series, multilevel models, survival analysis) and machine learning methods to identify trends, risk factors, and causal relationships that inform prevention strategies.
Conduct spatial analysis and GIS mapping to visualize crime hotspots, displacement effects, and environmental correlates of criminal activity, and incorporate spatial autocorrelation methods when appropriate.
Design and administer surveys, structured interviews, and focus groups; perform thematic coding and qualitative analysis to complement quantitative findings and capture lived experiences.
Develop and validate predictive models for operational use (e.g., risk assessments, hotspot forecasting), including evaluation of accuracy, fairness, and potential biases before deployment.
Evaluate crime reduction programs and policy initiatives using robust designs (randomized controlled trials, quasi-experimental approaches, interrupted time series) and produce evidence summaries with clear policy implications.
Produce clear, executive-level briefs, policy memos, peer-reviewed manuscripts, technical appendices, and public-facing reports that translate complex analyses into actionable recommendations.
Present findings to multidisciplinary stakeholders—police leadership, municipal officials, community groups, academic audiences—and facilitate evidence-based decision-making through workshops and presentations.
Advise on the development, implementation, and oversight of data governance, confidentiality, and ethical protocols for handling sensitive criminal justice data and vulnerable populations.
Collaborate with IT and data teams to design and maintain reproducible analytical pipelines, dashboards, and interactive visualizations to support ongoing monitoring and program management.
Provide expert testimony or technical consultation for legislative hearings, judicial proceedings, and policy advisory panels, grounded in methodological transparency and defensible evidence.
Lead grant writing and funding proposals to secure research support, manage budgets, and report to funders on methodological rigor and project impact.
Supervise and mentor graduate students, research assistants, and junior analysts, ensuring quality control for coding, data analysis, and reporting.
Conduct cost-benefit and cost-effectiveness analyses of interventions to support resource allocation decisions for agencies and funders.
Monitor and synthesize relevant literature, case law, and policy shifts to keep organizational strategies aligned with best evidence and evolving legal contexts.
Facilitate cross-sector partnerships—academia, public health, social services, community organizations—to design integrated, multi-disciplinary interventions addressing root causes of crime.
Implement and monitor key performance indicators (KPIs) for research and program outcomes, and adjust analytical approaches in response to operational feedback and changing priorities.
Translate research into training curricula and capacity-building materials for front-line staff, leadership, and community partners to improve adoption of evidence-based practices.
Conduct ethical reviews and risk assessments for research involving human subjects; ensure compliance with IRB, data-sharing agreements, and relevant privacy laws (e.g., CJIS, HIPAA where applicable).
Identify and mitigate sources of bias in data collection and analysis, including surveillance, reporting, and selection biases, and recommend strategies to improve equity and validity.
Support longitudinal studies and cohort tracking efforts to evaluate long-term impacts of interventions across justice system stages (prevention, policing, courts, corrections).

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Maintain and update internal knowledge bases, method libraries, and reproducible code repositories to accelerate future analyses.
Assist with community engagement efforts to solicit input on research priorities and disseminate findings in accessible formats.
Help standardize incident classification schemas and metadata standards to improve cross-agency interoperability and comparability.
