About

S. Waltersperger is a key figure in advancing macromolecular crystallography instrumentation, with a primary focus on developing innovative sample-handling technologies. Their most notable contribution is the design and implementation of the Parallel Robotics Inspired Goniometer (PRIGo), a compact, high-precision multi-axis goniometer introduced in a seminal 2015 paper (59 citations). This device offers a powerful alternative to traditional (mini-)kappa and Eulerian cradles, enabling rapid and precise sample reorientation for complex crystallographic experiments. By combining serial and parallel kinematic principles, PRIGo significantly enhances data collection efficiency and access to difficult crystal orientations, directly impacting structural biology studies. Waltersperger’s work addresses a critical bottleneck in high-throughput crystallography, providing a robust tool for researchers tackling challenging macromolecular structures. Their contributions have been widely adopted, with the PRIGo design influencing subsequent goniometer developments and facilitating more sophisticated diffraction experiments at synchrotrons worldwide.
