Research Interests

The ultimate goal of Dr. Benos’ laboratory is to help understand the molecular mechanisms and factors that facilitate a disease phenotype. They develop computational and statistical models to study gene expression regulation in a systems' biology framework. They analyze high-throughput expression data for protein coding and microRNA (miRNA) genes together with genome-wide DNA and RNA association data (ChIP-seq and CLIP-seq), and epigenetic data in order to identify biologically important and disease relevant gene (sub)networks. 

The main focus of Dr. Benos’ laboratory is on gene expression regulation, both at the transcriptional, post-transcriptional, and epigenetic level. Computational and mathematical methods are used to model cis-regulatory sites and modules, and miRNA targets; to find associations between the in vivo DNA binding affinity of transcription factors, the status of the chromatin and the expression level of their target genes; and to identify gene subneworks, and related polymorphisms or epigenetic marks that are critically associated to clinical phenotypes of terminal diseases, like pulmonary fibrosis and cancer. Dr. Benos’ laboratory continues to develop innovative computational methods to solve currently important biological and biomedical problems.
