Biographical Narrative

Dr. Brown obtained his Ph.D. in biomedical rngineering from Louisiana Tech University in 2005. As a graduate student, he pioneered the development of nano-engineered optical enzymatic glucose micro sensors for application to diabetic monitoring. He then moved to the Duke University Department of Biomedical Engineering, where he was a postdoctoral NRSA fellow (NCI), eventually being promoted to assistant research professor. During his tenure at Duke, Dr. Brown focused on applications of quantitative tissue spectroscopy and optical imaging for improving breast cancer patient outcomes. This included clinical investigations into the link between molecular subtype and tumor vascular oxygenation in vivo, and the use of quantitative diffuse optical imaging for intraoperative detection of residual cancer on the margins of tumor resection specimens. He moved to Tulane in 2012, where he is continuing translational research into the development and use of high-throughput fluorescence-enhanced optical microscopy for detection of positive surgical margins, ischemia and re-perfusion monitoring during partial nephrectomy, and sensing of the tumor microenvironment.
