Radiation Oncology Biostatistics & Biomathematics

The Division of Biostatistics & Biomathematics supports research-oriented databases and data management needs for Radiation Oncology.


The mission of the Division of Biostatistics & Biomathematics is to provide biostatistical leadership, collaboration, consultation and quantitative research resources to clinical and laboratory scientists engaged in the planning, conduct, analysis, quality assurance and interpretation of research studies. The Division of Biostatistics & Biomathematics provides an essential component of the scientific basis for clinical research conducted in the Department of Radiation Oncology:

  • Database development and management;
  • Developing designs for prospective clinical trials, laboratory experiments and observational studies;
  • Case-control analyses and retrospective reviews;
  • Statistical analysis of data arising from these trials, experiments and reviews;
  • Outcome analyses;
  • Mathematical modeling of clinical data, outcomes and clinical decision making;
  • Education of faculty and fellows;
  • Setting up Department policies insuring scientific integrity in all activities.
  • Services include:

    • Designing study forms and case report forms;
    • Assistance in writing protocols;
    • Database programming and development;
    • Randomizing patients;
    • Monitoring the course of a trial, ensuring that the protocol is followed;
    • Data entry;
    • Quality assurance and auditing;
    • Filing necessary forms to regulatory authorities;
    • Providing data summaries to the PI and raw data files to the trial’s biostatistician.
