About

Stephen Antonelli is a leading figure in synchrotron instrumentation and automation, whose work has revolutionized high-throughput structural biology. His primary research focuses on the development of advanced robotic sample changers and integrated software for macromolecular X-ray crystallography (MX) and biological small-angle X-ray scattering (bioSAXS). Antonelli’s major contributions include the design and implementation of fully automated, unattended data collection systems at the National Synchrotron Light Source II (NSLS-II). His landmark 2020 paper on the Life Science X-ray Scattering (LiX) beamline, which has garnered 78 citations, details the critical instrumentation enabling automated static measurements from PCR tube samples. Complementing this, his 2021 work on robotic sample changers for the MX beamlines AMX and FMX, cited 21 times, has been instrumental in enabling remote access and dramatically increasing throughput for the user community. By seamlessly integrating hardware and software, Antonelli has made synchrotron beamlines more accessible and efficient, empowering researchers worldwide to solve complex biological structures with unprecedented speed and ease.
