    Collapse Overview 
    Collapse overview
    My research interests lie in the broad area of bioinformatics, computational systems biology, and data mining. More specifically, my current research is focused on the following three directions: (1) module discovery and analysis in complex networks, with applications in protein complex prediction and microarray data clustering; (2) modeling and analysis of transcriptional/post-transcriptional regulatory networks (e.g. DNA motif finding and ChIP-seq data analysis); and (3) network-based biomarker discovery and disease classification via integrated analysis of heterogonous functional genomics data such as gene expression, protein-protein interactions, and microRNA-mRNA interactions. My research has been sponsored by NIH, NSF, and the San Antonio Life Sciences Institute.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
