About
Dr. Jessica M. Walker is a mechanical engineer and instrumentation scientist whose work centers on the development of high-precision positioning systems for advanced microscopy. Her most significant contribution is the design of the "Delta Robot," a novel, long-travel nano-positioning stage for scanning X-ray microscopy. This parallel kinematic design, which uses three orthogonal voice coils to actuate parallelogram flexures, achieves a remarkable 3 mm travel range while maintaining sub-nanometer RMS position jitter. This breakthrough directly addresses the critical need for both large scan areas and extreme stability in next-generation X-ray imaging. Her work on the Delta Robot, published in 2022, has already garnered 4 citations, signaling its growing importance in the synchrotron and X-ray microscopy communities. By enabling researchers to image larger samples with higher resolution and stability, Dr. Walker’s innovations are paving the way for new discoveries in materials science and biology. Her engineering contributions are foundational to the next generation of scanning probe and X-ray instruments.
