The tRopIcal DEep-sea Neutrino Telescope (TRIDENT) is a next-generation
neutrino observatory currently under development in the South China Sea. It is a 10 km3
detector, comprising an array of roughly 1000 vertical strings at a depth of about 3.5 km
below the sea level. TRIDENT is designed to extend the sensitivity of current neutrino
telescopes, with the primary goals of discovering multiple astrophysical neutrino sources and
enabling precision measurements of neutrino flavor composition. In this talk, I present a
concise overview of TRIDENT, its primary scientific objectives, my role within the
collaboration, and its current development status.
Dr. Sandeep Kumar Mondal obtained his PhD from the Raman Research Institute, India, in 2024. His doctoral research focused on high-energy astrophysical processes in active galactic nuclei (AGNs), particularly blazars. He was a postdoctoral fellow at ARIES for a short period in early 2025, after which he moved to the Tsung-Dao Lee Institute at Shanghai Jiao Tong University. His current research broadly focuses on high-energy and multi-messenger astrophysics. He is also a member of the TRIDENT collaboration, contributing to neutrino astronomy and next-generation detector development.
