Open Information Services (OIS)

Rigorous research for decisions that have to stand up to scrutiny.

Statistical analysis, program evaluation, and research services for doctoral students, government agencies, NGOs, and heritage or OSINT clients. Led by a former Head of Research (Israel Prison Service, Lt. Col., retired) with deep experience turning data into decisions.

Three clear paths to research

Pick the path that matches your situation. Each one leads to the services, tools, and track record relevant to you.

Government & NGOs

You need an external, senior evaluator who can produce evidence operational decision-makers will actually trust. Built on a large experience in a public-sector research branch.

  • Program evaluation with causal methods (PSM, IPTW)
  • Recidivism & risk modeling, classical and ML
  • Responsible AI review and policy advisory
  • Reports written for boards and ministries
See Public Policy

Researchers & Doctoral Students

You have a dataset, a research question, and a deadline. I handle the statistical analysis and methodology so your dissertation, paper, or report is defensible in review.

  • Dissertation statistics and methodology chapters
  • SPSS, R, Python, APA 7 reports
  • Survey design, sampling, power analysis
  • Qualitative analysis and mixed-methods design
See Classical Statistics

Heritage Organizations & Families

You are preserving a community's records, building a family history, or investigating an open-source trail. I design the platform, run the digitization, and deliver the dossier.

  • Heritage digitization, OCR & vision pipelines
  • Sephardic & Moroccan Jewish genealogy research
  • Social-media & forum archiving (OSINT)
  • Heritage Dossier PDFs, GEDCOM, platform builds
See Heritage & OSINT

Three connected practices.

One research discipline, applied across three domains that share the same rigor: quantitative method, honest framing, and deliverables clients can actually use.

One method, three domains

My work centered on recidivism prediction, rehabilitation program evaluation, terrorism studies (including research on terrorist recidivism following the Shalit prisoner exchange), and evidence-based corrections policy. That is the public-policy in practice.

Alongside it I run a growing digital heritage program focused on Moroccan Jewry: a Data-for-Good production platform (Yahasra.org) with 30,000+ burial records, archives of 29,000+ social-media posts from heritage groups, a dictionary of surnames, and a computational onomastics research program. The same infrastructure supports OSINT services for other clients: social network archiving, federated source aggregation, and open-source investigations. I also teach statistics and research methods at two universities, which keeps the classical-statistics consulting practice sharp.

  • Research Fellow, DHSS Hub, Open University of Israel. Computational diaspora studies, surname geography, quantitative onomastics.
  • Lecturer, Ariel University and Ashkelon Academic College. Academic writing, critical reading, SPSS.
  • Formerly Head of Research Branch, Israel Prison Service (retired Lt. Col.). Recidivism prediction, program evaluation, terrorism studies.
Service 02

Public Policy & Program Evaluation

Evidence-based evaluation for government agencies, NGOs, and criminal justice organizations. 25+ years embedded in the Israel Prison Service research branch, culminating in the role of Head of Research (retired Lt. Col.). I evaluate programs with causal methods, produce reports informing parole boards and corrections policy, and advise on responsible deployment of ML and AI in high-stakes decisions.
