Professor Mengkun Liu has built a distinctive research program that integrates advanced optical nanoscopy
quantum materials
and emergent light–matter interactions. As a Professor in the Department of Physics and Astronomy at Stony Brook University
he leads the Ultrafast & Near-field Infrared Laboratory (UNI-Lab)
where his group pioneers infrared-to-terahertz near-field spectroscopy under extreme conditions
enabling direct visualization of polaritons
collective excitations
and quantum phenomena at the nanoscale. Over the past decade
Professor Liu and his collaborators have not only made fundamental discoveries in quantum materials and nanophotonics but have also reshaped experimental capabilities through instrument innovation - ranging from magneto-near-field optical microscopy to synchrotron-based infrared nanoscopy. In this interview
he reflects on the scientific ideas that drive his research
the philosophy behind building a creative research group
and his perspective on the future of optical science at the quantum frontier.
