Jiwoo Nam is an experimental physicist specializing in the detection of ultra-high-energy (UHE) neutrinos and cosmic rays. His research leverages cutting-edge radio technology to explore extreme astrophysical phenomena. Key areas of his research include:

• Ultra-high-Energy Neutrino Detection: Development of novel neutrino telescopes using radio technology, including contributions to ANITA, ARA, ARIANNA, and TAROGE projects.
• Cosmic Ray Studies: Pioneering efforts in UHE cosmic ray detection through ground-based and balloon-borne experiments.
• BURSTT Project: Leading efforts in the first dedicated Fast Radio Burst (FRB) telescope in Taiwan, focusing on high-fluence FRBs and multi-messenger follow-ups.
• Instrumentation for Extreme Environments: Expertise in designing and constructing detectors for space, high mountains, and polar regions, addressing challenges such as harsh environmental conditions and remote locations.
• Future Prospects: Ongoing research includes enhancing the TAROGE-M project for UHE cosmic rays, advancing IceCube-Gen2 for GZK neutrinos, and expanding the BURSTT project to increase detection capabilities for FRBs.

Through these projects, Jiwoo Nam contributes to expanding our understanding of the universe's most energetic and elusive phenomena.
