Success Stories: Probing the Invisible: A Particle Physicist’s NIW Success in the Search for Dark Matter

Client’s Testimonial:

“Thank you for your help and service!”

On March 13^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the field of Particle Physics (Approval Notice).

General Field: Particle Physics

Position at the Time of Case Filing: Postdoctoral Researcher

Country of Origin: South Korea

State of Residence at the Time of Filing: California

Approval Notice Date: March 13^th, 2025

Processing Time: 1 year, 3 months, 16 days

Case Summary:

In the realm of fundamental science, where the universe’s deepest mysteries unfold particle by particle, one South Korean researcher has been making remarkable strides. With EB-2 NIW (National Interest Waiver) approval now secured, this postdoctoral researcher’s contributions to dark matter detection and cryogenic engineering have been formally recognized as vital to the national interest of the United States.

His field—particle physics—sits at the crossroads of theoretical depth and experimental ingenuity. Specializing in the development of magnetic quantum sensors, his research is central to detecting weak signals that may ultimately confirm the existence of dark matter. Operating within cryogenic environments, these sensors demand unmatched precision, and his work addresses both the conceptual framework and technical engineering required to make them viable.

His scientific record is not just impressive, but foundational. He has authored 27 peer-reviewed articles, including several first-authored papers, and his work has been cited over 8,500 times globally. At least 24 of his publications are ranked among the most highly cited in physics for their respective publication years.

Beyond publishing, his expertise has also been sought in peer review. He has conducted reviews for the Journal of Low Temperature Physics, and his contributions have informed major collaborative experiments, including the LUX and MADMAX projects—cornerstones in dark matter exploration.

A recommender captured the impact of his work succinctly:

“[Client]’s work with the MADMAX experiment led to the development of the first dielectric haloscope. This breakthrough is crucial for detecting axion dark matter as an alternative to traditional particle candidates. His system has been fabricated for commercial use and is already benefiting the global scientific community.”

Funding from the U.S. Department of Energy and the National Science Foundation has further validated the national value of his work. These projects are not theoretical exercises—they’re directly aligned with U.S. interests in quantum computing, national security, and scientific leadership. At present, he continues his research at a premier national laboratory, where he is developing next-generation cryogenic sensors and exploring new approaches to particle detection.

We successfully demonstrated in his NIW petition that his work not only addresses questions of universal significance, such as the nature of dark matter, but also provides engineering solutions that advance quantum information systems and high-precision sensor technologies.

At NAILG, we are proud to have supported this scientist in reaching a milestone that enables him to continue pushing the boundaries of discovery, work that could one day illuminate the darkest corners of the cosmos.
