“Brilliant people working toward a common goal” - Mathew Cherukara's Video Selfie

Mathew Cherukara of the U.S. Department of Energy’s Advanced Photon Source (APS) is featured this week in “Light Source Selfies,” a reoccurring series of videos on, the website for the international x-ray light source community.

Cherukara, who leads the X-ray Science Division Computational X-ray Science Group at the Argonne National Laboratory APS, uses his 1 minute 20 second video to offer glimpses of the APS experiment hall, describe his first impressions of an x-ray light source, put in a plug for the APS Upgrade Project, and introduce his excellent dog.

Watch Mathew’s video selfie, “Brilliant people working toward a common goal,” here.

All the video selfies can be seen here.


The U.S. Department of Energy's APS at Argonne National Laboratory is one of the world’s most productive x-ray light source facilities. Each year, the APS provides high-brightness x-ray beams to a diverse community of more than 5,000 researchers in materials science, chemistry, condensed matter physics, the life and environmental sciences, and applied research. Researchers using the APS produce over 2,000 publications each year detailing impactful discoveries, and solve more vital biological protein structures than users of any other x-ray light source research facility. APS 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 batteries to fuel injector sprays, all of which are the foundations of our nation’s economic, technological, and physical well-being.

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America's scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC, for the U.S. DOE Office of Science.

The U.S. Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit the Office of Science website.
