Ashton’s research expertise and interests are in cancer biology, specifically leukemia stem cell (LSC) biology. His graduate thesis work led to the discovery of novel gene sets and pathways critical for regulating LSC function. He also showed that perturbation of these gene sets through pharmacological interventions led to impairment of LSC function.

He has also focused on the development and refinement of gene transfer techniques in order to perform genetic manipulation in primary human leukemia patient samples to investigate mechanisms critical to LSC function. Currently, he is adapting single-cell transcriptomic methodologies for use with primary stem and progenitor cell populations to characterize molecular mechanisms underlying malignant stem cell biology.
