Assistant Professor of Medicine, Division of Biostatistics. Dr. Liu received his Ph.D. degree from Weldon School of Biomedical Engineering at Purdue University, and fulfilled his postdoctoral training in Dr. Howard Edenberg's laboratory at Indiana University School of Medicine. During his doctoral and postdoctoral research, Dr. Liu developed a series of mathematical models to identify transcription-factor binding motifs from array-derived gene expression data and genomic DNA sequences. The models demonstrated great potentials in aiding drug development, immunotherapeutics and gene therapy. Dr. Liu's current research interest focuses on developing computational and statistical methodologies in understanding transcriptional and post-transcriptional mechanisms underlying global gene and protein expression patterns.
