Joseph Siefert

Postdoctoral Fellow


I obtained my B.Sc. in biochemistry from the University of Wisconsin and my Ph.D. in cell biology from the University of Oklahoma. During my Ph.D., I pioneered the use of zebrafish as a model to study
DNA replication timing during development and discovered relationships between replication timing changes and enhancer activation. I then spent one year at Cancer Science Institute of Singapore analyzing mutations, gene fusions, and isoform changes in acute myeloid leukemia patients. I am joining Wilbert Zwart's team to study the genomics of breast and prostate cancer, with the goal of
identifying novel biomarkers for hormonal treatment response.
