Ravitej Uppu, Ph.D.

Title/Position
Assistant Professor
Phone
Ravi’s research investigates solid-state emitters coupled to a nanophotonic environment for realizing photonic qubits and spin-photon interfaces. He envisions that such nanophotonic devices will pave the way for real-world applications in quantum communication, simulation, and quantum-enhanced imaging. Ravi enjoys interacting with and training graduate and undergraduate students on optics, quantum physics, and statistical mechanics. Prior to UIowa, Ravi carried out research across the world [Niels Bohr Institute (Denmark), University of Twente (Netherlands), and TIFR (India)] and continues to maintain active international collaborations. Ravi is the lead PI of the UI-QuantumSimulation team that was awarded a Jumpstarting Tomorrow grant in 2021.
