Ph.D. from the University of Colorado in Physics, with expertise in ceramics/refractories; computer simulation/modeling; condensed matter; fatigue/fracture; mechanical properties, materials; physics, solid state and theoretical.

Hassold finds Kettering students driven, gifted and practical. He feels that what distinguishes them from students at other colleges is that "they're driven to practicality, with one eye on the job, and the other at school." Hassold was originally attracted to teaching at Kettering by the chance to teach high caliber students while continuing his own research and has discovered that "interacting with sharp, inquisitive students is rejuvenating!"

He would tell prospective students, "Kettering isn't for every student. . . but if there's a good fit between us, you won't find an educational experience like it anywhere else."

Hidden talents and outside interests: Hassold has a wide variety of interests outside Kettering. In addition to his family hosting high school exchange students with AFS, he enjoys music (choral, pipe organ), musical theater, travel, and photography.

Ronald Kumon

Assistant Professor of Physics Physics 2-323 J

Dr. Kumon received his B.S. in Physics and Mathematics from Michigan State University and his Ph.D. in Physics with specialization in physical acoustics from The University of Texas at Austin. He subsequently worked as a research physicist at the National Institutes of Standards and Technology (Materials Reliability Division), University of Windsor (Physics), Case Western Reserve University (Biomedical Engineering), and University of Michigan (Biomedical Engineering).

Dr. Kumon's research interests are broadly themed around the use of ultrasound for materials characterization, diagnostic imaging, and therapeutic applications. 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 pancreatic cancer. Dr. Kumon 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.  His most recent work has investigated the effects of HIFU on cardiac electrophysiology using optical and infrared imaging.

Dr. Kumon’s teaching experience has ranged from introductory to upper-division physics courses, mentoring undergraduate and graduate research projects, and instructing radiology residents in the physics and technology of ultrasound.  He is currently the advisor for both sections of Kettering’s Society of Physics Students (SPS) and Sigma Pi Sigma (Physics Honor Society) chapters. He appreciates the dedication of Kettering students and faculty alike in their efforts to promote an environment for productive teaching and learning.

Daniel Ludwigsen

Associate Professor of Physics Physics 1700 University Ave
2-323 L AB

Hide Bio

Ph.D. from Brigham Young University in Physics and Musical Acoustics, with expertise in underwater acoustics, African instruments and acoustic resonators, brass instruments, noise and vibration.

Dedicated to excellence in teaching, Ludwigsen is currently developing two new Acoustics courses and a course in methods of computer use in Physics. He is also the principal investigator for a National Science Foundation grant to Kettering to redesign the Physics I laboratory to include new teaching methodology and crash safety study.

Recognizing that a great deal of discovery in Physics comes from playing with toys, trying to see how things work and "getting inside the black boxes," he enjoys Kettering students' willingness to join in the pursuit of figuring out why toys, and the world more generally, behave the way they do.

Ludwigsen finds that the kind of learning that really "sticks" comes from active learning, so he asks his students to take responsibility for their education. "Learning deeply and effectively is, in the long run, worth the time and effort," he said.
