Stefanie S. Jeffrey, MD
John and Marva Warnock Professor, Emerita
Current Research and Scholarly InterestsDr. Jeffrey led the multidisciplinary team from the Schools of Medicine, Engineering, and Genome Technology Center that invented the MagSweeper, an automated device that immunomagnetically captures live circulating tumor cells (CTCs) from cancer patient blood for single cell analysis or culture. Her lab also works on microfluidic technologies for tumor cell capture, characterization, and growth - with the goal of defining individual patient response to newer biologically-based cancer therapies.
