Ronald Kumon Bio PicRonald Kumon, Ph.D.





Ronald Kumon received his B.S. in Physics and Mathematics from Michigan State University in 1992 and his Ph.D. in Physics with specialization in physical acoustics from The University of Texas at Austin in 1999. He subsequently held appointments as a physicist at the National Institutes of Standards and Technology in Boulder, Colorado, Department of Physics at the University of Windsor in Windsor, Ontario, Department of Biomedical Engineering at Case Western Reserve University in Cleveland, Ohio, and Department of Biomedical Engineering at the University of Michigan in Ann Arbor. In 2010, he became a member of the research faculty in Biomedical Engineering at U-M in Ann Arbor.

Dr. Kumon's research interests are broadly themed around the use of ultrasound for materials characterization, diagnostic imaging, and therapeutic applications. As an extension of his doctoral work on nonlinear surface acoustic waves in crystals, he has studied the characterization of thin-film systems using surface acoustic waves. In the biomedical arena, he has investigated high-frequency ultrasound for ex vivo characterization of breast cancer and endoscopic ultrasound for improved in vivo diagnosis of chronic pancreatitis and pancreatic cancer. He has also studied the mechanisms and bioeffects of sonoporation, the therapeutic use of ultrasound and microbubbles to enhance the delivery of drugs to cells, via fluorescence and high-speed brightfield microscopy. Most recently, he has been working to better understand the biophysical effects of high-intensity focused ultrasound on cardiac electrophysiology in the context of atrial fibrillation using optical and infrared imaging.

Dr. Kumon joined Lawrence Technological University as an adjunct faculty member during Fall 2010. He has experience teaching undergraduate physics laboratory courses, lecturing undergraduates and graduate students in condensed matter physics, mentoring undergraduate and graduate research projects, and instructing radiology residents in the physics and technology of ultrasound.
