Welcome to the KRG at Texas A&M!

At KRG, we develop a fundamental understanding of coupled dynamics across electromagnetic, acoustic, photonic, and thermal domains, from classical interactions to emerging quantum behavior, in multifunctional material systems.

We translate that understanding into RF microelectronic and micro/nano-system technologies: ferroic ordering, piezoelectricity, wave–matter coupling, and nonlinear responses engineered into scalable devices, integrated circuits, and systems that advance next-generation communication, computation, sensing, and timing.
