Dr. Ellen Langer received her Ph.D. from Washington University in St. Louis in 2007. In her doctoral research in the lab of Dr.Gregory Longmore, she identified a role for Ajuba LIM proteins as corepressors of the Snail family of proteins. Using Xenopus neural crest as an in vivo model of epithelial to mesenchymal transitions (EMT), she found that Ajuba LIM proteins are essential for Snail function. Dr. Langer began her postdoctoral research in the labs of Dr. Kenneth Murphy at Washington University and Dr. Mario Capecchi at the University of Utah. There, she studied early fate specification in embryonic stem (ES) cells and found that Snail, which induces an EMT in ES cells, also induces endothelial differentiation. In 2011, Dr. Langer joined the lab of Dr. Rosalie Sears at OHSU where she studies the impact of cell stress and the tumor microenvironment on cancer cell heterogeneity, plasticity, and metastasis. Her current projects include investigating the regulation of vascular mimicry in breast cancer cells and interrogating how tumor microenvironment proteins and cells contribute to tumorigenic phenotypes using 2-dimensional cell culture, mouse modeling, and 3d-bioprinting.
