About Me

I am a researcher at Oak Ridge National Laboratory (ORNL). Before joining ORNL, I was a senior research scientist at the Center for Innovation for Flow Through Porous Media (COIFPM) in Fort Collins, CO where I worked on multiscale imaging and image super-resolution using Generative Adversarial Networks (GAN), and then a President’s Postdoctoral Fellow (PPFP) at the Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. My research focuses on multiphase fluid-structure interaction, flow through porous media, dehydrogenation of catalytic reactors, application of digital twins in advanced manufacturing, smart renewable packaging, sustainability, decarbonization, and artificial intelligence (AI).
