Efthymios Papageorgiou, Ph.D. 2019

Electrical Engineering
Advisor: Prof. Boser
Research Interests: Biomedical Imaging, Integrated Biomedical Systems, BioMEMS, Integrated Circuits

Efthymios is a Ph.D. student in integrated circuits in Prof. Bernhard Boser's research group. He is co-advised by Prof. Mekhail Anwar, M.D. of UCSF. His research interests are circuits for biomedical applications and he is currently working on a micro fluorescence imager for breast cancer detection. He graduated from Columbia University in Spring of 2014 with a B.Sc. degree.

Real-Time Intraoperative Fluorescence Imager for Microscopic Residual Tumor in Breast Cancer [BPN685]
Successful treatment of early stage cancer depends on the ability to resect both gross and microscopic
disease, yet no method exists to identify residual cancer cells intraoperatively. This is particularly problematic in
breast cancer, where microscopic residual disease can double the rate of cancer returning, from 15% to 30% over
15 years, affecting a striking 37,500 women annually. Currently, residual disease can only be identified by
examining excised tumor under a microscope, visualizing tumor cells stained with specific tumor markers. This
microscopic evaluation restricts identification of tumor cells to the post-operative setting. Unfortunately, traditional
optics cannot be scaled to the sub-centimeter size necessary to fit into the cavity and be readily manipulated over
the entire surface area. To solve this problem, we have developed an imaging strategy that forgoes external optical
elements for focusing light and instead uses angle-selective gratings patterned in the metal interconnect of a
standard CMOS process.
