Profile
I am a combustion researcher specializing in premixed flame dynamics, with a focus on hydrogen combustion, flame instabilities (DL and TD), and low-carbon fuel applications. My work combines advanced laser diagnostics—such as high-speed PIV and 3D swinging laser sheet techniques—with experimental and numerical methods to investigate laminar and turbulent burning behavior. Currently graduted from Derek Bradley’s combustiom group at the University of Leeds, I have published in leading journals and collaborate with industry and national labs to support the development of net-zero combustion technologies.
Research interests
My research focuses on the fundamental and applied aspects of flame dynamics, with particular emphasis on premixed combustion and flame instability mechanisms. I specialize in measuring laminar and turbulent burning velocities to characterize combustion behaviors under a wide range of conditions, including high-pressure and hydrogen-rich environments. A significant portion of my work investigates the effects of Darrieus–Landau (DL) and thermal-diffusion (TD) instabilities on flame propagation and morphology, especially in lean hydrogen–air mixtures where intrinsic instabilities dominate flame dynamics.
To support these investigations, I employ a suite of advanced laser diagnostic techniques, including high-speed Particle Image Velocimetry (PIV) and a novel 3D swinging laser sheet tomography method, enabling dynamic reconstruction of complex flame surfaces and flow fields. My ongoing efforts are directed toward the characterization of carbon-free fuel combustion, such as hydrogen and ammonia, to advance low-emission and high-efficiency energy systems.
