Dr Lee's principal research interest lies in the field of fluid dynamics and computational engineering.

He is currently involved in various research projects focusing on the interaction between fluid and solid mechanics, with particular interest in coating of thin liquid films, sprays, rivulets, droplets and the dynamic interaction of interfaces in multi-phase flows. This includes free-surface flows, moving interfaces, dynamic solid-fluid interactions and high velocity impact deformation of solid feedstock on surfaces.

His is also actively involved the development of accurate and efficient numerical solvers to help inform, understand and resolve multi-physical problems. This encompass the development of both mesh and mesh-less solvers, utilising efficient numerical techniques to accelerate computation of solutions. Among grid-based methodologies used are spatial and temporal adaptivity with Multigrid (MG) approaches while mesh-less ones are performed using Smoothed Particle Hydrodynamics (SPH). Both numerical approaches aims to fully exploit the HPC resource at CER by making full use of both CPU and GPU capabilities.

Dr Y.C. Lee graduated from the School of Mechanical Engineering at the University of Leeds in 1999 where he received an M.Eng (Hons) degree in Mechanical Engineering. Upon completion of his Ph.D. in Mechanical Engineering in 2004, he took up a position as a post-doctorate researcher at the Institute of Engineering Thermofluids, Surfaces & Interfaces (iETSI) where he worked in the area of Engineering Fluid Mechanics and grew his expertise in Computational Fluid Dynamics. He developed accurate and efficient numerical solvers for the coating of thin liquid films, rivulets and droplets using adaptive, local mesh refinement and Multigrid techniques which accelerate solutions to complex multi-phase dynamic solid-liquid interactions and multi-physical problems. Soon after, he worked as a named researcher in an EPSRC project, utilising High Performance Computing (HPC) and his experience to lead the development of a parallel solver for lubrication based problems. He has also worked in various projects in areas ranging from micro-channel flows in micro-fluidics, porous media flows in reservoirs and to scale deposition kinetics in petroleum distributed pipelines.

In 2010, Dr Y.C. Lee was offered a lectureship position in the School of Engineering and Physical Sciences at Heriot-Watt University where he continued to pursue his interest in education and research in fluid dynamics.
