Russell S. Witte graduated, with honors, with a Bachelor of Science in physics from the University of Arizona and a doctorate in bioengineering from Arizona State University, where he used electrode arrays to study sensory coding and learning-induced plasticity in the brain. As a postdoctoral fellow at the University of Michigan, he helped devise state-of-the-art techniques to image the nervous and musculoskeletal systems. He is now associate professor of medical imaging, biomedical engineering and optical sciences at the University of Arizona.

His Experimental Ultrasound and Neural Imaging Laboratory devises hybrid imaging methods that integrate light, ultrasound, and microwaves for advanced imaging with novel contrast. These noninvasive techniques, such as acoustoelectric imaging, thermoacoustic imaging, and ultrasound elastography, quantify changes in the electrical, optical and/or mechanical properties of tissue at high spatial resolution.

The ultimate goal of his research is to improve patient care by providing tools that improve diagnostic accuracy and treatment-decision making for a variety of conditions ranging from epilepsy and arrhythmia to tendinopathy and cancer.
