Research talks

2022 July
Most GWAS associations have been found outside protein-coding genes, leading to growing interest in studying non-coding DNA to understand biology and treat disease. In this talk, I'll present my group's recent work on methods development for analysis of genomic intervals. Through algorithmic advances and novel machine learning applications, we have developed several approaches to study non-coding genomic intervals in new ways. I'll also present applications and results of these approaches to recent questions in cancer biology.
