In the early years of my career I have focused on high resolution CT and MRI of the temporal bone and other skull base structures. In collaboration with Dr. Petra Schmalbrock we have developed and implemented a number of advanced techniques for MRI at 1.5 T, many of which have since become standard techniques available on commercial units. We have documented the value of these techniques related to the clinical evaluation of patients with tumors and other pathology. We were interested in the physics of MR imaging and wrote a book together titled “Fundamentals of Magnetic Resonance Imaging”.

From 1999- 2004 I have worked on the development of ultra-high field MRI at 8 T. I was the Director of the MRI Research Division at the OSU Medical School, Department of Radiology for an interval. We focused on achieving a better understanding of many of the critical fundamental issues that presently represent significant limitations to high field MR imaging. These limitations include: B1 field inhomogeneity, high SAR values, magnetic susceptibility artifacts, volume head coil configurations, and non-standard relaxometry techniques. My primary clinical focus was on high resolution imaging of the micro circulation of the brain, applications of phase imaging, and brain anatomic studies.

We completed extensive safety numerical simulations, phantom measurements and human studies. This data lead to the FDA revising the safety standard to include exposure to 8 T as a non-significant risk imaging device.

I have had the opportunity to pursue an interest in unified physics theories since the late 1990s. It is now a mature model titled the Harmonic Neutron Hypothesis. Below are links to five of the published papers describing the mathematics and physics. These papers contain detailed mathematical information, but are not easy reading though accurate. There is also a copyrighted paper from 2006 that described my early work that I could not get published. The main concepts in the copyright paper are correct, but some of the details are not fully accurate. The model has been significantly improved in the interval. The most important predictions of that2006 paper have been proved correct.  The following introduction is also available as a link. There are some Matlab files as well that can be downloaded and used to corroborate my results directly. They can be used as starting blocks to begin your own calculations. 

Below is also a more generalized description meant to be an introduction. It is a mixture for a layman’s audience and a more sophisticated mathematical/ physics audience. Forgive me, it is not ideal for either. It is written in a narrative didactic form. Musical properties will be used as an analogy to simplify the mathematics and concepts.  Though music is not completely applicable to the global physics domain, the music concepts do accurately describe most of the mathematical concepts of this physical model.   The term domain refers to a general area with a common characteristic.
