Krishen Appavoo

Dr. Krishen Appavoo is an Associate Professor in the Department of Physics at the University of Alabama at Birmingham's College of Arts and Sciences. He directs the Laboratory for Nanoscale and Quantum Photonics, focusing on light-matter interactions at ultrafast timescales and nanoscale dimensions.

His research investigates quantum materials, nanostructured electronic systems, and ultrafast spectroscopy for energy and optoelectronic applications. Major projects include time-varying metamaterials, quantum nanosystems, and energy nanomaterials like hybrid perovskites. His work integrates nanofabrication with advanced optical characterization techniques including femtosecond transient spectroscopy and energy-momentum imaging.

Dr. Appavoo mentors numerous graduate and undergraduate researchers, maintaining active collaborations with Brookhaven National Laboratory and Rice University. His research has been funded by NSF, NASA, and Alabama EPSCoR, resulting in publications in journals such as Science, Nature Communications, and Advanced Optical Materials.
