Yoseob Yoon is an Assistant Professor in the Department of Mechanical and Industrial Engineering and an Affiliated Faculty in the Department of Physics at Northeastern University. He is also a Core Faculty in the Quantum Materials and Sensing Institute. Before joining Northeastern, he was a Postdoctoral Scholar in the Department of Physics at the University of California, Berkeley and the Materials Sciences Division at Lawrence Berkeley National Laboratory. He received his Ph.D. in Physical Chemistry from the Massachusetts Institute of Technology and B.S. in Chemistry from Pohang University of Science and Technology.

He is an experimental condensed matter and quantum physicist specializing in the ultrafast control and spectroscopy of low-dimensional quantum materials. His research focuses on inducing strong electronic correlations through engineered van der Waals heterostructures, strong THz fields, and photonic cavities. He investigates how light-matter and matter-matter interactions give rise to emergent quantum-mechanical properties, with a focus on achieving quantum control of material properties through enhanced interactions. To this end, he employs advanced spectroscopic techniques across visible to THz frequencies to probe ultrafast dynamics, enhanced interactions, and transport of quasiparticles—including excitons, phonons, magnons, polarons, and polaritons—in quantum materials.
