**About the Editors**

**Xueding Wang** Optical Imaging Laboratory at the U-M School of Medicine, is focused on imaging system development, and the adaptation of novel diagnostic and therapeutic technologies to laboratory research and clinical settings, especially those involving light and ultrasound. A major part of our research is focused on the clinical applications of photoacoustic imaging, including those involving breast cancer, inflammatory arthritis, prostate cancer, liver conditions, bowel disease, eye conditions and brain disorders. We are also interested in the design and fabrication of multi-functional nanoparticle agents (e.g., metallic, hydrogel) for both diagnosis and therapy, as well as interactions between nanoparticles and cells.

**Xinmai Yang** is currently an associate professor at Department of Mechanical Engineering and Institute for Bioengineering Research at the University of Kansas. He is an expert in acoustic/optical imaging and therapy with an extensive background in biomedical ultrasound and photoacoustic imaging. His research extends from linear acoustics to non-linear acoustics and laser/ultrasound interaction, including acoustic cavitation, high-intensity focused ultrasound, and photoacoustic imaging. His current research interest focuses on combining light and ultrasound for imaging and therapy. His primary contributions are in the areas of cavitation bubble dynamics in soft tissue under high-intensity ultrasound, photoacoustic brain imaging, and photo-mediated ultrasound therapy.

**Xose Luis Dean-Ben** received his Automatics and Electronics Engineering and PhD degrees from the University of Vigo in 2004 and 2009, respectively. Since 2010, he has been working in the field of optoacoustic (photoacoustic) imaging. He contributed to the development of both new systems and processing algorithms, as well as to the demonstration of new bio-medical applications in cancer, cardiovascular biology and neuroscience. Currently, he serves as a senior scientist and group leader at the University of Zurich and ETH Z ¨ urich. He has co-authored more than 60 papers in peer-reviewed ¨ journals on optoacoustic imaging.
