Jaeyun graduated from Caltech with a PhD in mechanical engineering. He received his bachelor's degree in mechanical engineering at Georgia Tech, where he did research in thermal transport in carbon fibers with President. G. P. "Bud" Peterson and in water management in proton exchange membrane fuel cells with Professor Tequila Harris. As a graduate student in mechanical engineering in Professor Austin Minnich's group, he studied thermal transport in amorphous materials using both numerical and experimental techniques. His research focused on finding out how heat carriers (propagons, diffusons, and locons) transport heat differently in amorphous materials from phonons in crystals. Understanding heat transfer mechanisms in amorphous materials could enable us to synthesize novel materials with exceptionally low thermal conductivity.
