Prof. Trilochan Sahoo advances teaching and research in marine hydrodynamics through rigorous semi-analytical modelling that combines hydroelasticity, coastal hydrodynamics, and complex wave phenomena. His work includes wave interaction with flexible, porous, and mixed surfaces, helping to understand wave interaction with floating and submerged structures, soft seabeds, and coastal protection systems. He has significantly improved our understanding of wave interactions with undulated seabeds and structures, as well as with mangroves and flexible surfaces. His research also looks at flexural–gravity wave blocking, wave trapping, and Bragg scattering over periodic beds, providing a profound understanding of multi-scale wave dynamics influenced by dispersion, structural flexibility, and environmental forcing, and creating a strong theoretical basis for applications involving very large floating structures, floating ice sheets, and coastal protection systems.

A comprehensive record of his publications and citation metrics is available on his Google Scholar profile (https://scholar.google.com/citations?user=OkwQ5M4AAAAJ&hl=en), which documents his contributions and impact in coastal hydrodynamics and hydroelasticity. Furthermore, his MathSciNet author profile (https://mathscinet.ams.org/mathscinet/MRAuthorID/604074) highlights his sustained and recognised contributions to the mathematical sciences. Over the last 25 years, he has guided 30 doctoral and postdoctoral fellows on various aspects of wave-structure interaction and has overseen more than 100 UG/PG projects in ocean engineering. Besides, he has published 159 journal papers and 122 conference papers, collaborated with several established researchers in India and abroad, and mentored several scholars at sister institutes in India. He is featured among the top two percent of global scientists as per SCOPUS database

He offers a vibrant research environment for pursuing marine hydrodynamics research, especially on water waves, for students of applied mathematics, mechanical, civil and physical sciences. His work aligns with national priorities, such as the Sagarmala Program and the Blue Economy. His group invites students committed to nation-building through maritime research to join year-round. Details can be found at https://www.iitkgp.ac.in/rolling-phd-admission
