Description of Research Expertise

While broadly interested in computational biology, we focus on biological questions pertaining to eukaryotic gene regulation and its evolution. We develop computational approaches to harness the huge amount of biological data (genomes, transcriptomes, proteomes, microarray, Chip-seq etc) to answer specific questions pertaining to gene regulation and molecular evolution. Within these parameters, anything is a fair game. Our current research activities include: (1) Characterizing transcription factor DNA interactions, (2) Identifying Cis-regulatory Modules (3) Modeling Modification-dependent activity of transcription factors, (4) Investigating the evolution of transcriptional regulation, and (5) Characterizing natural selection on regulatory elements.
