Postdoctoral Fellows

Mike Sano, PhD | CAP Profile
Dr. Sano studies the complex interaction between biological systems and electromagnetic fields. His research focuses on the development of advanced cancer detection, imaging, and treatment platforms. As a graduate student he developed a technique for building custom tissue scaffolds from the nano-scale up using electric fields to manipulate biological processes. For his Ph.D. he developed a platform technology for detecting cancer, contactless dielectrophoresis (cDEP), which sorts cells based on their electrical properties. As a postdoctoral fellow, he has been developing a minimally invasive cancer therapy, high frequency irreversible electroporation (H-FIRE), which destroys tumors using brief yet intense electrical pulses. Dr. Sano was also recently awarded the DOD Prostate Cancer Research Fellowship to study photo-acoustic ultrasound imaging techniques for distinguishing benign from malignant prostate cancer.
