His general research interests include, but are not limited to, Statistical Genetics, Time Series Analysis, Survival Analysis, Functional Smoothing, Bootstrap, Subsampling, Nonparametric Statistics, Density Estimation, Simulation, Bayesian Statistics, and Longitudinal Data Analysis. As a faculty member of Penn State's Center for Statistical Genetics, Dr. Berg is passionate about unlocking the mysteries of DNA and its connection to human health. Located in the newly constructed Cancer Institute on the Penn State Hershey campus, Dr. Berg works in close proximity to clinical researchers allowing for convenient collaborations on grants and publications across all areas of human health.

Anna Salzberg

Senior Bioinfomaticist in the Penn State College of Medicine's Bioinformatics Core. Anna Salzberg has had over 10 years experience working in industry as a software engineer. More recently she became very enthusiastic about Bioinformatics and Biology and during the last 10 years she worked as a bioinformatician first at Pfizer and then at the Penn State College of Medicine. At Pfizer, she co-developed protein structure computational geometry algorithms to predict target "druggability", as well as novel graph theoretic algorithms for binding site fingerprinting to predict function and small molecule selectivity. At Penn State she is involved in developing algorithms for bioinformatics and computational biology, including genomics and epigenomics.
