Professional Services

Biostatistical expert testimony and independent data monitoring for clinical trials.

In addition to academic research, I maintain two ongoing professional practices outside of Penn State: biostatistical expert-witness services in medical and scientific litigation, and independent data monitoring for pharmaceutical and academic clinical trials. Both draw on the same methodological toolkit — careful study design, quantitative reasoning under uncertainty, and clear statistical communication to non-statistical audiences.

Expert Witness Services

What I offer

I provide biostatistical expert opinions and testimony in medical malpractice, pharmaceutical, and scientific causation matters, with engagements that typically include:

  • Written expert reports quantifying statistical evidence, epidemiological risk, or scientific reliability
  • Deposition testimony and trial testimony in state and federal courts
  • Daubert/Frye admissibility analyses and rebuttals of opposing experts
  • Literature review and critical appraisal of published studies, meta-analyses, and regulatory submissions
  • Case consultation with counsel on statistical strategy and discovery

Areas of emphasis

  • Medical malpractice involving diagnostic performance and clinical decision-making
  • Pharmacoepidemiology and adverse-event causation
  • Interpretation of clinical-trial endpoints and regulatory evidence
  • Scientific methodology disputes involving probability, sampling, or causal inference

Engagement & fees

I take a limited number of matters each year to ensure careful, personal attention. My current fee schedule is available on request — please reach out via email with a brief description of the matter, jurisdiction, and anticipated timeline, and I will respond with availability and rates.

A curriculum vitae is available here for filings and disclosures.

Independent Data Monitoring

DSMC/DMC roles

I serve as an independent biostatistician on Data Safety and Monitoring Committees (DSMCs) and Data Monitoring Committees (DMCs) for investigator-initiated and industry-sponsored clinical trials. Responsibilities include:

  • Pre-trial review of statistical-monitoring plans and stopping rules
  • Unblinded interim analyses of efficacy and safety
  • Presentation of statistical reports to DSMC/DMC deliberations
  • Ad hoc consultation on signal evaluation, sample-size adaptation, and protocol amendments

Prior engagements

  • Penn State Cancer Institute Data Safety and Monitoring Committee — Member (2024–2026), with additional earlier service to Penn State Cancer Institute research-oversight committees.
  • Industry-sponsored pharmaceutical DMCs — Independent biostatistician on multiple sponsor-led clinical trials spanning oncology and other therapeutic areas. (Specific sponsors and study details are governed by confidentiality agreements.)

If your sponsor or academic center is seeking an independent DMC biostatistician, please contact me to discuss fit, availability, and conflict checks.
