Senior Scientist, Group Lead
Computing
Responsibilities
Alexander Hexemer leads the Photon Science Computing Group (PSC), which provides computational support and expertise for ALS beamlines and users. PSC develops software tools, data analysis methods, and machine-learning approaches to help scientists work effectively with synchrotron data. Our team collaborates with researchers on projects ranging from basic data processing assistance to developing new computational techniques for challenging experiments. We also work closely with NERSC to create efficient data storage and management solutions, ensuring that the large datasets generated at the ALS are properly preserved and accessible for analysis.

Professional Experience
Alex joined the ALS as a postdoc and later became a staff scientist to work as a beamline scientist at the SAXS/WAXS beamline. In 2013, he received a DOE Early Career Award to work on a “Photon Science Tool Kit,” and in 2018, he transitioned to leading the Computing Program at ALS. He is now a senior scientist and leads the Photon Science Computing Group. He also serves on the cross–light source and neutron source data and computing committee, the “Light Source Data and Computing Steering Committee.
