Biography

 

Brad Roth was born in Clinton, Iowa in 1960, and was raised in Morrison, Illinois. He attended Homestead High School in Fort Wayne, Indiana (1974-76), Ashland High School in Ashland, Ohio (1976-77) and Shawnee Mission South High School in Overland Park, Kansas (1977-78). From 1978-1982 he attended the University of Kansas in Lawrence, Kansas, supported in part by a National Merit Scholarship. While at KU he majored in Physics (BS, 1982) and received the Stranathan Award, the highest honor awarded by the KU physics department to an undergraduate. In 1982, he entered Vanderbilt University in Nashville, Tennessee (MS, 1985; PhD, 1987) on a NSF Graduate Fellowship. His graduate research was performed in the Living State Physics Laboratory, headed by Dr. John Wikswo. This work resulted in the first detailed comparison of the transmembrane potential and magnetic field produced by an isolated nerve axon, and the prediction of electrically silent magnetic fields generated by electrical activity at the apex of the heart. After obtaining his PhD, Dr. Roth remained at Vanderbilt for a year as an American Heart Association Research Fellow, during which time he developed Fourier methods for solving the magnetic inverse problem with two-dimensional current sources.

 

In 1988, Dr. Roth joined the Biomedical Engineering and Instrumentation Program at the National Institutes of Health in Bethesda, Maryland. His research at NIH centered on three themes: cardiac electrophysiology, magnetic stimulation of nerves, and analysis of the electroencephalogram. His work on the heart was directed toward developing the bidomain model of cardiac tissue, and using it to understand problems such as defibrillation, arrhythmia generation, and anodal stimulation (For a popular account of this research, see Science, 303:786-787, Feb. 6, 2004). Dr. Roth's work on magnetic stimulation involved calculating the electric field induced in the brain, determining the site of excitation of a peripheral nerve, and coil design. His studies of the EEG required development of a realistically shaped head model to localize the source of electrical activity in patients who are candidates for epilepsy surgery. In 2011, Dr. Roth's publications were cited in the scientific literature over 200 times. For years, a figure from one of Dr. Roth's publications (Roth, Balish, Gorbach, and Sato, Electroenceph. clin. Neurophysiol., 87:175-184, 1993) graced the cover of the journal Electroencephalography and clinical Neurophysiology.

From 1995 to 1998, Dr. Roth was the Robert T. Lagemann Assistant Professor of Living State Physics in the Department of Physics & Astronomy at Vanderbilt University. In 1998, he became an Associate Professor in the Department of Physics at Oakland University, where he is now a Professor and continues his research in theoretical cardiac electrophysiology, and teaches physics. He is coauthor of the textbook Intermediate Physics for Medicine and Biology.

In 2006 he was elected a Fellow of the American Physical Society (Division of Biological Physics). His citation reads:

 

"For his theoretical and numerical studies of bioelectric and biomagnetic phenomena, especially for his contributions to the bidomain model of the heart."
