I have developed systems for minimally invasive cardiac surgery, motion tracking using optical and inertial sensing, accuracy-enhanced microsurgery using active handheld robotic instruments, steering of needles for neurosurgical and urological procedures, and filtering of command input in assistive interfaces for computers and powered wheelchairs. I have published over 130 peer-reviewed papers in these areas. I have been a Senior Member of the IEEE, and the director of a surgical robotics laboratory. I hold one U.S. patent, with another provisional patent application submitted. I have prior experience providing consultations, reports, declarations, claim construction opinions, deposition, and courtroom testimony as a medical robotics expert witness.

Roadside Safety Engineering Expert 523144 AL

Expertise Description

I am experienced in the field of roadside safety engineering. While working at a prominent research institute in the field of transportation safety engineering, I assisted in constructing roadside and median safety features for the purpose of conducting standardized crash testing according to NCHRP Report 350 and MASH test protocols. I also documented some of those tests by recording observations, taking measurements of various forms of damage, and compiling technical reports. I also researched ditches, crash cushions, low-volume roads, trees, cable guardrail, W-beam guardrail, concrete median barriers, and temporary concrete barriers. I also investigated the fracture behavior of thin steel under dynamic loading conditions. I am familiar with dynamic and static component testing, computer simulation via LS-Dyna, and full-scale crash testing for Federal approval of highway safety appurtenances. I have also taught classes on elasticity, continuum mechanics, fracture mechanics, and LS-Dyna. I have also conducted a statistical analysis of the in-service performance of guardrail terminals. I have offered my services as a roadside safety engineering expert witness by providing consultations, courtroom testimony, and deposition.
