About me
About me
Greetings! I am Jaber Al Hossain, Ph.D., currently a Postdoctoral Researcher (InnoCORE Fellow) at Ulsan National Institute of Science and Technology (UNIST), working under the supervision of Professor Taesung Kim.
My research focuses on nanoscale transport phenomena, molecular dynamics simulation, nanofluidics, and interfacial transport under extreme confinement. I am particularly interested in wall–fluid interactions, molecular friction, continuum breakdown, and molecular-to-continuum modeling.
My current research is expanding these molecular-scale insights toward multiscale thermal-fluid modeling and semiconductor package thermal management, integrating molecular dynamics, CFD, and physics-informed/AI-based approaches.
I received my Ph.D. in Mechanical Engineering from the University of Ulsan under the supervision of Professor BoHung Kim.

This study uses molecular dynamics simulations to show how liquid transport in nanogrooves changes as confinement approaches the one-nanometer scale. Strong molecular layering and exclusion reduce the accessible flow region, causing continuum predictions to break down. The results provide a geometry-resolved transport baseline for nanogroove design relevant to next-generation semiconductor etching.

At the molecular scale, the repulsive forces acting inside a nanopore become more dominant; considering proper boundary approximation is essential for pores with a sub-1 nm radius for pressure-driven flow through the nanoporous graphene membrane applications.
