Dr. D. Kacy Cullen is a Professor of Neurosurgery & Bioengineering at the Perelman School of Medicine at the University of Pennsylvania. He received a Ph.D. in Biomedical Engineering from the Georgia Institute of Technology (2005), followed by postdoctoral fellowships in Neuroengineering at Georgia Tech (2005-2006) and then at the Center for Brain Injury & Repair at Penn (2007-2009). Dr. Cullen is an internationally recognized leader in tissue engineering, regenerative medicine, and translational bioengineering and has authored over 150 peer-reviewed scientific publications (h-index 49). He is a pioneer in advanced tissue manufacturing, including microtissue engineering to restore brain and spinal circuitry, composite (multi-cellular) tissue engineering, and innervation-driven organogenesis. He has also made seminal advancements in the development of living biological electrodes for biohybrid neuroprosthetic interfaces. Dr. Cullen is committed to the translation of advanced medical technologies and regenerative therapies. He is an inventor on over 25 patents in the U.S. and internationally. He has also founded multiple biotechnology companies focused on translation of first-in-class tissue engineered medical products for peripheral nerve, spinal cord, and brain reconstruction, as well as surgical assistive devices and anti-degenerative biologic therapeutics.
