Dr. Arvind P. Pathak is an Associate Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science and the Department of Oncology. His work focuses on the molecular imaging of cancerous tumors. Dr. Pathak received his B.S. in electronics engineering from the University of Poona, India, in 1993, and in 2001 completed his Ph.D. in biophysics and biomedical engineering at the Medical College of Wisconsin/Marquette University in Milwaukee, Wisconsin. After a fellowship in radiology at Johns Hopkins University, he joined the Johns Hopkins staff as an instructor in 2003 and became a faculty member in 2005. Dr. Pathak has garnered numerous awards for his research, and has published over 40 articles in peer-reviewed journals. He is a member of the International Society for Magnetic Resonance in Medicine and the American Association of Cancer Research. More information: Pathak Lab

Muyinatu A. Lediju Bell (informally known as "Bisi") leads a highly interdisciplinary research program that integrates optics, acoustics, robotics, electronics, and mechanics, as well as signal processing and medical device design, to engineer and deploy innovative biomedical imaging systems that simultaneously address unmet clinical needs and significantly improve the standard of patient care. As the director of the Photoacoustic and Ultrasonic Systems Engineering (PULSE) Lab, Dr. Bell develops theories, models, and simulations to investigate advanced beamforming techniques for improving ultrasonic and photoacoustic image quality. In parallel, she designs and builds novel light delivery systems for photoacoustic imaging and incorporates medical robots to improve operator maneuverability and enable standardized procedures for more personalized medicine. The technologies developed in her lab are then interfaced with patients to facilitate clinical translation. These technologies have applications in neurosurgical navigation, cardiovascular disease, women’s health, and cancer detection and treatment. Dr. Bell obtained a PhD in Biomedical Engineering from Duke University and a BS in Mechanical Engineering with a minor in Biomedical Engineering from the Massachusetts Institute of Technology. In addition, she spent a year abroad as an academic visitor at the Institute of Cancer Research and Royal Marsden Hospital in the United Kingdom. Prior to joining the faculty, Dr. Bell was a postdoctoral fellow with the Engineering Research Center for Computer-Integrated Surgical Systems and Technology at Johns Hopkins University. She published over 40 scientific journal articles and conference papers, holds a patent for SLSC beamforming, and is the recipient of numerous awards, grants, and fellowships, including the prestigious NIH K99/R00 Pathway to Independence Award.

Dr. Xingde Li's research interest centers on development of cutting-edge and translational biophotonics technologies that interface and bridge basic engineering research and medical diagnosis and intervention. The research and training involves vertical integration of multiple disciplines, including (but not limited to) optics, electrical engineering, micro-nano technology, biology and clinical medicine. The ultimate goal of our research is to transform our capability of disease detection at early, manageable stages, monitoring therapeutic effects and treatment outcomes, and guiding interventions. The technologies also offer new opportunities for basic research in exploring new frontiers of disease mechanisms, brain function, bio-marker discovery and integrated diagnosis and therapy.
