Bascom Palmer Eye Institute


The Biostatistics Core collaborates with researchers in a wide range of areas related to study design, data collection/management, statistical analysis, and interpretation of results for meeting presentations and publications.

Portions of the Biostatistics Core are supported by NEI Core Center Grant P30 EY014801. Please cite this grant number on all publications that make use of the portions of this core that are supported by this award.

Leadership & Management

Richard K. Parrish, II M.D. is the Director of the Biostatistics Module. He serves as Professor of Ophthalmology as Associate Dean for Graduate Medical Education at the University of Miami Miller School of Medicine, and as Director of the Glaucoma Service. Joyce Schiffman M.S. serves as manager of the Biostatistics core. William Feuer M.S., a leader in ophthalmology research, has been a biostatistician with Bascom Palmer since 1985. Wei Shi M.S., a biostatistician; Luz Ajuria, a research coordinator; and Yolanda Silva, a programmer/database manager contribute statistical, quality control, and data management expertise to our research projects. This Core has been consistently supported by NEI grants since 1981.


The Biostatistics Core is located on the 15th floor of the Clinical Research Building.

Areas in which the Biostatistics Core assists researchers

Experimental Design

Evaluate the feasibility of research projects, provide sample size and power estimates, as well as randomization schedules, case-control selection, and relevant variables to be documented.

Research Protocol Development

Assist researchers in the development of laboratory, experimental model, and clinical experiments, including developing Manuals of Procedures and data collection forms for clinical trials and epidemiologic studies.

Statistical Coordinating Center Activities

These activities include randomization and follow-up on patients for multicenter, randomized clinical trials; data collection and management; data analysis; and convening Safety and Data Monitoring Committee (SDMC) meetings.

Data Analysis and Interpretation

The Core can assist researchers with statistical analysis and interpretation for a wide range of studies.

Proposal and Report Preparation

Collaborate with researchers in preparing grant applications, reports for Data and Safety Monitoring Committees, manuscripts, and presentations.

Training and Education

The biostatisticians teach residents and fellows who prepare annual research projects about appropriate study design, analysis, and interpretation of results specific to their project (laboratory, experimental model, clinical).
