Dr. Ray has over 10 years of research experience in the field of cell and developmental biology. She obtained her PhD in 2007 from the Department of Biological Sciences at the University of Illinois at Chicago (UIC), where she studied the neurodevelopment of Caenorhabditis elegans. During her postdoctoral studies she became interested in cancer biology where she studied the role of chemokine receptors (CXCR4 and CXCR7) in breast cancer metastasis. As a Research Investigator in the Department of Radiation Oncology she studies factors that regulate the stability of various oncoproteins including Epidermal Growth Factor Receptor (EGFR) and mutant KRAS. She is also actively involved in collaborative research identifying ubiquitin ligases (E3s) responsible for regulating protein stabilities of various oncogenes including mutant TP53 and CYP24A1.
