Recently, I attended TAUP 2025 (19th International Conference on Topics in Astroparticle and Underground Physics) in Xichang, Sichuan, China, and gave an oral presentation on August 27 titled “Towards imaging Earth’s large-scale structures by directional geoneutrino detection with the Ocean Bottom Detector.” In my talk, I briefly reviewed KamLAND’s past geoneutrino detections and introduced the future OBD (Ocean Bottom Detector) project, and discussed whether, if OBD had angular resolution, we could resolve the LLSVPs (Large Low Shear Velocity Provinces) and measure the concentration of radioactive elements within them.

The session was well attended, and although the Q&A time was limited to only 5 minutes, I received questions from 4 different participants. After the session, I also had fruitful discussions with senior colleagues in the neutrino community, especially on topics such as neutrino direction reconstruction and novel liquid scintillators.

During the conference, I had the opportunity to visit the China Jinping Underground Laboratory (CJPL), where I was impressed by China’s recent progress in underground experiments, neutrinoless double beta decay searches, and neutrino physics. I also made many new friends and connections in the community.

Another exciting highlight was the news that JUNO (Jiangmen Underground Neutrino Observatory) has officially started data-taking, which generated great enthusiasm among participants. We all look forward to their outstanding results.

This was my first time attending an international conference. Although I felt a bit nervous, I received very valuable advice and feedback. The experience allowed me to learn from leading researchers, exchange ideas with peers, and gain a deeper understanding of the current developments in neutrino physics. I look forward to applying these insights in my future research and continuing to engage with the community.
