“We look beyond the linear sequence of DNA to understand how the three-dimensional architecture of the genomes influences a wide range of biological processes from the malignant transformation of cancer cells to the life cycle of the deadly malaria parasite.”
Overview
The focus of Dr. Ay’s work is to understand gene regulation in complex organisms and diseases by developing novel methods that leverage high-throughput genomics and epigenomics data. He develops computational methods that are based in statistics, machine learning, optimization and graph theory. He is particularly interested in the analysis and modeling of the 3D genome architecture from high-throughput chromatin conformation capture data to understand how do changes in this 3D architecture affect cellular outcome such as development, differentiation, gene expression and disease phenotypes. He is also interested in uncovering epigenetic mechanisms behind precise regulation of gene expression in the deadly malaria parasite Plasmodium falciparum during its sexual and asexual life cycles. He also has ongoing interests in systems level analysis and reconstruction of regulatory networks, inference of enhancer-promoter contacts, predictive models of gene expression and integration of chromatin conformation data sets with one-dimensional measurements such as histone modifications, nucleosome occupancy and DNA accessibility.

After one exact year (March 8th 2020-2021), I returned back to my office two weeks ago the same way I left plus lysol wipes. Not sure if my productivity went up but my morale and motivation certainly did. Work-from-home is great when you choose to do so, not when you have to :)
