RESEARCH SUMMARY
Dr. Baek’s primary research interest is in computational biology and biostatistics. He has made a significant impact on bioinformatics and biological interpretation of research involving analysis of DnaseI hypersensitive sites, digital genomic footprinting, and comparative enrichment analysis. His contributions have led to a better understanding of the global chromatin landscape and the elucidation of transcriptional mechanisms. Dr. Baek is also interested in the development of a novel bioinformatics algorithm for the analysis of high-throughput multi-omics data.

Research
My research goal is to further the understanding of transcriptional regulation, especially the identification and characterization of chromatin modifications that lead to modifications and transitions of gene activation, repression, and epigenetic inheritance. My specific interests include statistical and bioinformatic analysis of multi-omics data (involving ChIP-, DNase-, ATAC-, and RNA- seq) and their interpretation. These efforts will provide novel methods for elucidation of mechanisms underlying epigenetic regulation of gene expression in cancer and also will help to improve integration of clinical data involving cancer from patient samples.
Recently, I have developed a highly sophisticated algorithm for identifying short genomic regions (footprints) which enable analysis of transcriptional activities at the nucleotide resolution. The algorithm has been implemented in Dnase2TF, a public domain software platform used by many biology groups for high-throughput analysis of digital genomic footprinting. I collaborate widely at NIH and with the extramural scientific community and have several publications with groups at the University of Southern Denmark, the University of Washington, The Pennsylvania State University, the University of Bristol, etc.

Biography
Songjoon Baek, Ph.D.
Dr. Songjoon Baek completed his B.S and M.S. in mathematics at Sogang University in Seoul, South Korea in 1997 and obtained a Ph.D. in applied mathematics and statistics at the State University of New York at Stony Brook in 2004. His Ph.D. studies focused on statistical analysis of high-dimensional data. After finishing his postdoctoral training at Seoul National University and at the U.S. Food and Drug Administration (FDA), Dr. Baek joined the Laboratory of Receptor Biology and Gene Expression, Center for Cancer Research, NCI as a Staff Scientist in 2009.
