  • Professor of Electrical Engineering, City College of New York
  • Affiliate Faculty, Photonics Initiative, Nanoscience Initiative

Research Interests

Alexander Khanikaev’s group focuses on experimental research and theoretical studies of photonic nanostructures and metamaterials aiming to develop novel optical systems and devices with previously unattainable properties and useful functionalities. The research includes an interdisciplinary studies at the edge of optics and such disciplines as biology and condensed matter physics. One of the major research directions is engineering topological order and nonreciprocity in photonic nanostructures with magneto-optical and bianisotropic responses. The bio-oriented research program of the group is aiming to facilitate in-depth characterization of bio-molecules with the use infrared spectroscopy of plasmonic nanostructures and metamaterials.
