EPI_BIO 445-0 Data Science for Clinical, Translational, and Population Researchers (1 Unit)

Due to advances in technology and data collection, the ability to analyze complex data sets is a necessary skill for all clinical, translational and population researchers. A variety of data analysis tools exist, some unique to specific domains. This course provides an introduction to the data, analysis tools, ethical considerations, and terminologies from across biomedical data science with an emphasis on clinical, translational and population methods and tools.

EPI_BIO 446-0 Design, Conduct, and Analysis of Clinical Trials (1 Unit)

This is an Introduction to clinical trials, including design, conduct, analysis and interpretation of trial results. Topics include trial design, methods for randomization, blinding and sample size determination, choice of controls, operational issues, data management and data quality issues, interim analysis methods, critical review of clinical trial proposals and published results and statistical techniques for analyzing clinical trial data.

EPI_BIO 499-0 Independent Study (0.5-1 Unit)

This is Independent Study course is designed to give students a hands-on practical training on statistical analysis. This course will offer 4 statistical consultation projects -- real case study. Students will be given the data and a brief introduction of the data. Students will need to check the data, perform preliminary data analysis, orally present their statistical approach, modeling, findings, and interpretation of their result, and write a report for each project. Students will be evaluated by the quality of their oral presentation and project report.

EPI_BIO 501-0 Advanced Epidemiology (1 Unit)

This course builds on material learned in previous Biostatistics and Epidemiology courses. Concepts are applied to the design, implementation, analysis and interpretation of observational epidemiologic studies (cross-sectional, case-control and cohort). Students enrolled in an MPH degree program must have the consent of the instructor.

Prerequisites: EPI_BIO 301-0, EPI_BIO 302-0, EPI_BIO 401-0, EPI_BIO 402-0.

EPI_BIO 502-0 Advanced Biostatistics (1 Unit)

This course covers modern approaches to the analysis of correlated response data arising from longitudinal studies commonly encountered in medical research and clinical trials. Concepts include marginal and mixed-effects regression models for continuous and discrete outcomes measured repeatedly over time, model building techniques, robust inference procedures and problems associated with missing data. All modeling and numerical analyses will be done using SAS.  Prerequisites include the equivalent of EPI_BIO 302-0, EPI_BIO 402-0.

EPI_BIO 521-0 Applied Survival Data Analysis (1 Unit)
