Biography

I have diverse interests in turbulence, supported by my background in atmospheric sciences and mechanical engineering. My primary tools include large-eddy simulation (LES), direct numerical simulation (DNS), and machine learning. My research focuses on turbulence modeling and its influence on the atmospheric boundary layer, tornadoes, and cloud-aerosol-turbulence interactions.
