Bascom Palmer Eye Institute

About the Biostatistics Center

The Biostatistics Center (BSC) provides laboratory and clinical research investigators with collaborative expertise and assistance with research and clinical trials study design, data management, and biostatistical analysis.


The ODRC is directed by ophthalmologist and glaucoma specialist Richard K. Parrish, II, M.D. Dr. Parrish is a Professor of Ophthalmology and currently serves the University as Associate Dean for Graduate Medical Education. He previously served as chair of the department of ophthalmology from 1996 to 1999.

Chief Biostatistician and Staff Scientist Joyce Schiffman, M.S. is the founding member of the BSC. Throughout her tenure, she has worked closely with the faculty and house staff to design, implement, analyze, and publish various clinical studies in ophthalmology. She has served as the principal investigator and in other roles on NEI and industry-supported multi-center clinical trials.

Biostatistician and Staff Scientist William Feuer, M.S. is also a long-term member of the BSC. He has served on multiple NEI-supported multi-center clinical trials. He also has worked with many of the laboratory researchers. Mr. Feuer presents seminars on statistical study design and relevant statistical methods to the faculty, residents, and fellows.

Giovanni Gregori, Ph.D. was recruited to the Bascom Palmer faculty as a Research Assistant Professor in September, 2002. He received his doctorate in mathematics and his research interests include mathematical modeling and optics. During his training, Dr. Gregori completed a 2.5 year senior fellowship at the Huntsman Cancer Institute, University of Utah, where he received training in biostatistics. Dr. Gregori utilizes his biostatistics and mathematics expertise to provide routine support for the NEI-funded projects of CVR investigators, and he acts as a collaborator on more extensive projects.

Biostatistics Staff

Biostatistician Wei Shi, M.S. is a new recruit to the BSC. Since her arrival she has acquired diverse experience working on both clinical and laboratory research projects.

Computer Resources

All personal computers are linked via an EtherNet network running Microsoft network software that provides password protected file sharing in addition to Outlook e-mail services, TelNet, and FTP. The University of Miami is served by an FDDI backbone, which ties together EtherNet hubs linking all major buildings including those comprising the Bascom Palmer Eye Institute. High speed digital links connect this network to the Internet in general, and the resources of the University of Miami Coral Gables campus and the School of Marine and Atmospheric Sciences in particular. These provide access to IBM and DEC mainframe computers, which run all common statistical packages such as SAS, SPSSX, BMDP, and Minitab.


The BSC is located within the Ophthalmic Clinical Research Center in 6,000 sq feet of space on the 15th floor of the medical school’s new Clinical Research Building.
