The program builds the Department of Energy national laboratory leaders of the future.

The  (OSELP) has announced the selection of fellows for its 2025 cohort. Representing the U.S. Department of Energy’s (DOE) Argonne National Laboratory in the program will be Daniel Haskel, a group leader in the lab’s X-ray Science Division.

OSELP is managed by the National Laboratory Directors’ Council (NLDC), a group made up of directors of DOE national laboratories.

Haskel leads the Magnetic Materials group at the Advanced Photon Source (APS), a DOE Office of Science user facility at Argonne. The group is responsible for operations and R&D activities at four , including a new feature beamline under commissioning as part of a comprehensive upgrade to the APS. That beamline, Polarization Modulation Spectroscopy, will advance research in energy-efficient materials and quantum technologies.

“Daniel is an important leader within the scientific staff at the APS, and his knowledge and ideas will no doubt enrich this latest OSELP cohort and its mission.” — Jonathan Lang, Director, X-ray Science Division, Argonne

The 2025 cohort includes representatives from all 17 DOE national laboratories. Haskel was chosen to represent Argonne after a lab-wide internal selection process. Candidate nominations are assessed by a committee of former national lab directors and former senior DOE officials, and accepted into the program by the NLDC.

“Daniel’s selection to OSELP is certainly well deserved,” said Jonathan Lang, director of the X-ray Science Division. â€‹“Daniel is an important leader within the scientific staff at the APS, and his knowledge and ideas will no doubt enrich this latest OSELP cohort and its mission.”

As the premier leadership development program of the NLDC, the  is dedicated to preparing the national lab leaders of tomorrow. Throughout the year, the cohort will visit several DOE labs and develop strategic think-pieces as part of an effort to immerse its fellows in the scope and intricacy of the national laboratory system. The goal of the program is to cultivate leaders that will have long-term impacts throughout the complex.

“I am delighted to have the opportunity to learn more about the broader DOE national laboratory complex,” Haskel said. â€‹“Each laboratory is unique yet driven by the common mission of solving the most pressing scientific and technological problems of our times. It is a privilege to be able to get a closer look at the inner workings of such an incredibly impactful resource for the nation.”

About the Advanced Photon Source

The U. S. Department of Energy Office of Science’s Advanced Photon Source (APS) at Argonne National Laboratory is one of the world’s most productive X-ray light source facilities. The APS provides high-brightness X-ray beams to a diverse community of researchers in materials science, chemistry, condensed matter physics, the life and environmental sciences, and applied research. These X-rays are ideally suited for explorations of materials and biological structures; elemental distribution; chemical, magnetic, electronic states; and a wide range of technologically important engineering systems from to fuel injector sprays, all of which are the foundations of our nation’s economic, technological, and physical well-being. Each year, more than 5,000 researchers use the APS to produce over 2,000 publications detailing impactful discoveries, and solve more vital biological protein structures than users of any other X-ray light source research facility. APS scientists and engineers innovate technology that is at the heart of advancing accelerator and light-source operations. This includes the insertion devices that produce extreme-brightness X-rays prized by researchers, lenses that focus the X-rays down to a few nanometers, instrumentation that maximizes the way the X-rays interact with samples being studied, and software that gathers and manages the massive quantity of data resulting from discovery research at the APS.

This research used resources of the Advanced Photon Source, a U.S. DOE Office of Science User Facility operated for the DOE Office of Science by Argonne National Laboratory under Contract No. DE-AC02-06CH11357.
