I am a board-certified Emergency Medicine physician and Bioengineer with specialized expertise in injury causation analysis, independent medical examinations (IMEs), and medico-legal evaluation of trauma related to motor vehicle collisions. I currently serve as Medical Director of a clinic, where my clinical and analytical work is focused almost exclusively on collision-related injuries. My practice emphasizes mechanism-based medical analysis, integrating clinical medicine with principles of biomechanics, occupant kinematics, and force transmission. I routinely evaluate whether reported injuries are medically and biomechanically consistent with the described event, with careful consideration of timing, symptom progression, imaging findings, and alternative etiologies. With a foundation in engineering principles and decades of frontline trauma experience, I provide clear, defensible medical opinions grounded in objective data and peer-accepted medical reasoning. My work includes co...
