Dr. Qianqian Fang /房骞骞/ is an Assistant Professor of Bioengineering at Northeastern University, with an affiliated position in the Electrical and Computer Engineering Department. After receiving his Bachelor's Degree in Electrical Engineering from the University of Electronic Science and Technology of China, he completed his PhD degree in Biomedical Engineering at the Thayer School of Engineering, Dartmouth College (NH, USA). He joined the Martinos Center of Biomedical Imaging at Massachusetts General Hospita/Harvard Medical School for his postdoctral training between 2005 and 2009, and became an Instructor of Radiology in 2009 and Assistant Professor in 2012, before he jointed Northeastern University in 2015.

Dr. Fang's interests focus on innovations in translational medical imaging devices to better diagnose cancers, low-cost point-of-care diagnostic tools to deliver life-saving medicines to the resource-poor regions, and high performance computing tools to facilitate the development of the next-generation imaging methods. Recent awards include Leading Innovation in Reimagining Global Health through the Innovation Countdown 2030 Initiative and an NIH R01 grant for developing "A Versatile High-Performance Optical Mammography Co-Imager."

Current Postdoctoral Fellows

Dr. Zafer Dogan


Dr. Zafer Dogan is a postdoctoral research associate. His research interests are at the intersection of data processing, inverse problems, and machine learning, but his current work focuses on developing signal and image processing methods in emerging optical imaging modalities using sparse signal models and inverse problems in nonlinear diffusion optical tomography. He received his M.Sc and Ph.D. degrees in Electrical Engineering from Ecole Polytechique Federale de Lausanne (EPFL), Switzerland, in 2011 and 2015, respectively. Dr. Dogan is also jointly affiliated as research associate at Harvard University John A. Paulson School of Engineering and Applied Sciences where his work focuses on online and distributed learning algorithms for large-scale non-convex optimization problems.
