MathWorks software engineer. Background: Ph.D. at the University of Rochester (NY) with focus on neurophysiology, visual and vestibular systems, multisensory integration, sensory-motor systems, control systems, steering, and navigation. My contributions to MATLAB Central before 14-Feb-2022 were prior to my employment at MathWorks. "If I had only one hour to save the world, I would spend fifty-five minutes defining the problem, and only five minutes finding the solution. -Albert Einstein "An expert is a person who has made all the mistakes that can be made in a very narrow field." -Niels Bohr "If you are not embarrassed by the first version of your product, you've launched too late" - Reid Hoffman
