MathWorks software engineer with interests in data analysis and visualization. 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.
