Research Areas

Steenacker’s PhD work focuses on understanding how diseases, such as cancer, are associated with dramatic changes in glycan patterns, with a special interest in the relationship between complex ganglioside expression and breast cancer cell proliferation, migration and invasion. After completing her doctorate at the University of Lille, France, she worked as a post-doctoral fellow in the university’s Structural and Functional Glycobiology Laboratory where she focused on O-GlcNAc modifications in colorectal cancer development. 

Her second post-doctoral training was in the Laboratory of Cellular and Molecular Biology at the National Institutes of Health (NIH) in Bethesda, MD. Her research at the NIH focused on determining the full-length structures of the enzymes responsible for O-GlcNAc modifications using cryogenic electron microscopy (cryo-EM). She also worked on different aspects of O-GlcNAcylation, where she developed a liver O-GlcNAcase knockout mouse model. She then employed this to study the impact of O-GlcNAcylation on metabolic syndrome development.
