Ioannis Chatzakis

Ioannis Chatzakis is an Assistant Professor in the Department of Physics and Astronomy at Texas Tech University, specializing in nanomaterials and ultrafast dynamics of charge carriers, phonons, and polaritons for next-generation optoelectronic and photonic devices.

His educational background includes:

• B.Sc. in Electrical Engineering
• M.Sc. in Physical Chemistry (Applied Molecular Spectroscopy)
• Ph.D. in Physics from Kansas State University (2009)

Dr. Chatzakis investigates fundamental light-matter interactions in nanomaterials, with emphasis on terahertz generation/modulation, sub-diffraction light confinement, and quantum information systems using single-photon sources. His work bridges condensed matter physics and quantum engineering to develop novel device functionalities.

Analysis of his 2021-2025 publications reveals dominant research themes in graphene, hexagonal boron nitride, and 2D heterostructures, focusing on carrier dynamics, phonon interactions, and terahertz optoelectronics with applications in quantum computing and nanophotonics.

His notable awards include:

• USC Provost's Postdoctoral Scholar Research Grant
• American Society for Engineering Education (ASEE) Postdoctoral Fellowship

Dr. Chatzakis secured competitive postdoctoral funding including the USC Provost's grant for terahertz devices based on artificial multilayer graphene and the ASEE fellowship at the U.S. Naval Research Laboratory, though current grant details are not specified in the source material.

His laboratory employs femtosecond pump-probe spectroscopy and complementary optical techniques to study ultrafast dynamics in nanomaterials, supporting research in quantum emitters and terahertz modulators.
