Master of Public Health Nationally-known faculty Leading-edge information technologies Challenging, real-world experiences A dynamic collaboration with the Louisville Metro Health Department provides first-hand opportunities to address public health challenges in a top-20 U.S. city
What is biostatistics? Biostatistics involves the development and application of statistical techniques to scientific research in health-related fields, including medicine, epidemiology, and public health.

What is Bioinformatics? The science of informatics as applied to biological research. Informatics is the management and analysis of data using advanced computing techniques. Statisticians are supposed to be experts in analyzing data
What kind of data? Usually, in bioinformatics we deal with genomics, proteomics or metabolomics data. Example: Microarray data, Mass Spectrometry data and high dimensional data from different metabolites.
DNA Microarray A DNA microarray (or "chip") enables the geneticist to monitor the expression patterns of numerous genes (potentially all of the genes in a given cell type) at the same time. Example: Finding genes/biomarkers for cancer Identify the set of genes that are “differentially expressed” between normal and cancer cells microarray experiment among two (or more) cell types e.g., 1 = normal cell; 2 = cancer cell
Analyzing Microarray Data: Goal: to find differentially expressed genes Problem: obscure variability mixed with true Solution (using Statistics!)
Biological question Differentially expressed genes Sample class prediction etc. Testing Biological verification and interpretation Microarray experiment Estimation Experimental design Image analysis Normalization Clustering Discrimination R, G 16-bit TIFF files (Rfg, Rbg), (Gfg, Gbg)
Decision Science Understanding decision making in the context of public health To understand how decisions are made To improve decision making To study specific decision making problems
Combination of clinical research methodology, biostatistics, and psychology All of these areas of interest have an impact on clinical decision making
Decision Analysis An explicit process to understand a decision and make the best decision in the face of uncertainty.
