Publications
Mr. Stevens has written numerous peer-reviewed research papers and a book chapter, publishing both domestically and internationally. The topics of these publications and presentations include vehicle rollover analysis, reconstruction of collisions resulting from tire failure, vehicle handling, and the flammability of the various vehicle fluids which can be released during a collision. He also holds a patent for the design of a fiber optic strain gauge.
