Dr. Walker has worked at Manhattan College more than 20 years, and is currently conducting research in the area of biomechanics specifically on various orthodontic projects and one long term study that is examining Shaken Baby Syndrome. He has also been a consultant on various projects that have included system failure issues, testing protocols, and signal data analysis.
In the past, Dr. Walker did research on rocket nozzle design, which involved obtaining blast and sound wave data and processing the signals to extract salient pressure wave information. His work in signal processing introduced him to the field of system dynamics with an emphasis on instrumentation and robot sensors.
