Faculty Research Interests
John Abrams, Ph.D.
Our lab applies genetic systems to explore how pivotal tumor suppressors function to control stem cell biology.
Michalis Agathocleous, Ph.D.

We are using a combination of mouse genetics, metabolomics, and stem cell biology approaches to investigate the function of metabolic pathways in stem cells and cancers in vivo.
Laura Banaszynski, Ph.D.
Our long-term goal is to determine how chromatin influences developmental cell-fate decisions. We take the view that chromatin acts as both a platform for the integration of signaling information received from local cellular environments, as well as a regulator of gene expression changes required for cellular response to those signals. We use a combination of molecular biology, biochemistry, and genomics to study these questions in the context of preimplantation development, embryonic and adult stem cell biology, and cancer.
