Robert Bruno earned a Ph.D. in Molecular Medicine from the University of Maryland School of Medicine in 2009 for his work on a novel prostate cancer therapeutic (galeterone) which is now in Phase III clinical trials. He then completed a post-doctoral fellowship at the National Cancer Institute in the Mammary Stem Cell Section of the Basic Research Laboratory at the Center for Cancer Research. He came to Â鶹´«Ã½ in 2013 as an Assistant Professor in the School of Medical Diagnostic & Translational Sciences within the College of Health Sciences. His current work applies biomedical engineering principles including 3D bioprinting to study mechanisms of cellular fate determination in development, cancer, and neurodegeneration.

Research Interests

My research focuses on understanding how the local microenvironment controls cellular differentiation and function. We study this in the context of cancer, development, and neurological disorders. Notably, we have shown that we can redirect breast cancer cells to adopt a normal mammary epithelial cell fate by restoring a normal microenvironment around them. This has huge implications for diagnosis and treatment of cancer. We use a combination of techniques including 3D bioprinting, induced pluripotent stem cells, in vivo models, and novel 3D culture techniques to understand the process.
