I am a postdoctoral researcher in cancer biology and genetics. My main project aims to characterize the different genetic subclasses of uterine leiomyoma (UL). In particular, the study aims to uncover distinct features of ULs by investigating chromatin accessibility, genome architecture and transcriptional activity in the 4 main genetic subclasses of the tumor, analyzing both flash-frozen and fresh samples. The techniques I am currently employing are ATAC-seq, ChIP-seq and Hi-C. Beyond this, I exploit CRISPR/Cas9 technique to generate UL cell line derived from myometrium immortalized cells.

I’m a PhD student in the early phases of my project. My main focus is on studying environmental causes of tumorigenesis by trying to detect patterns of genetic damage in the tumors of patients who have had substantial exposure to carcinogenic agents due to their work environment or lifestyle choices. Finding such patients for study involves utilizing data sets gathered by Finnish national institutes over the past decades. Another branch of my project concerns using the same data to recognize familial cancer clustering that cannot be readily explained by previously known cancer syndromes, the reason behind which we will then study at the genomic level.
