Dr. McIlrath's research interests are in developing "intelligent" imaging devices for use in machine vision, robotics, and image processing. In her Ph.D thesis "Computing 3-D Motion in Custom Analog and Digital VLSI", she studied the problem of creating a complete system with specialized VLSI processors to compute the relative motion of two cameras. She has published several papers on the theory and design of analog processors for low-level vision operations, including a working 32x32 array CCD/CMOS focal-plane edge detector, and an analog binary block correlation chip. She is currently investigating focal-plane and 3-dimensional smart imagers based on CMOS active pixel arrays and is co-PI on the DARPA funded program: "3-D Computational Sensors for Advanced Low Power Visual Processing". Dr. McIlrath received an NSF Faculty Early Development CAREER Award in 1996.
