I am familiarized with genetic and molecular biology tools in general and culture of different cell lines. I have special interest in all issues related to transcriptomics, genomics, epigenomics and proteomics technologies. I am especially interested in areas related to genetics and molecular biology

Research Interests

Genomic, transcriptomic, proteomic and biology molecular in general
