Andrei Sirenko

Andrei Sirenko is Professor of Physics at NJIT with research expertise in terahertz spectroscopy, optical properties of quantum materials, and magneto-optical phenomena. His experimental program investigates phonon dynamics, magnetic excitations, and phase transitions in multiferroic systems using advanced spectroscopic techniques.

Current work focuses on developing vortex beam technologies for magnetic spectroscopy and synchrotron-based infrared/THz facilities. Research employs terahertz spectroscopy, Raman scattering, and ellipsometry to probe spin-phonon coupling and electronic correlations in complex oxides.

Publications demonstrate consistent methodology development in spectroscopic techniques with applications to quantum materials. Recent work emphasizes chiral magnetic structures, interface physics, and terahertz beam engineering.

Contributes to major instrumentation projects including the NSLS-II synchrotron facility. Research supported by NSF and DOE grants for materials characterization and device physics.
