Prosper Ngabonziza / Group Leader
Assistant Professor of Physics – Louisiana State University (2022~)
Ph.D., 2016 – The University of Twente, The Netherlands
Prosper Ngabonziza is an Assistant Professor of Physics in the Department of Physics & Astronomy of the Louisiana State University. After receiving a Bachelor of Science degree (BSc. in Physics) from the University of Rwanda (former National University of Rwanda), he completed with cum laude, in 2010, a postgraduate diploma in mathematical sciences at African Institute for Mathematical Sciences (AIMS), under the University of Cape Town in South Africa. In 2012, he completed a Master’s degree with cum laude in experimental physics from the University of Johannesburg in South Africa.
He received in 2013 the S2A3 Bronze Medal awarded by the Southern Africa association for advancement of science to the best student who did a most meritorious master dissertation in a science department in South Africa. In 2016, he completed a PhD in engineering physics from the University of Twente, in The Netherlands. His PhD project was on topological insulators (TIs). He was combining thin film growth, characterizations and quantum transport studies of TIs. From October 2016, he was a Postdoc at the Max Planck Institute for Solid State Research in Stuttgart-Germany, in the department of solid-state quantum electronics.
His research at Max Planck focused on quantum matter heterostructures fabricated from complex oxides with the goal to explore novel phenomena in devices fabricated from such heterostructures. After 6 years at Max Planck Institute, he joined the faculty at the Louisiana State University in 2022.

Senior Postdoctoral Researcher: Dr. Arnaud Nono Tchiomo
My field of interest includes condensed matter physics, with a focus on materials science. I have a particular love for the understanding of the behavior of materials, as well as the optimization of their functional properties which can lead to their integration in various modern optoelectronics and transparent electronic devices. I am a proficient and independent lab experimentalist, experienced in the growth of oxide thin films using pulsed laser deposition (PLD), and applying a suite of characterization of the physical properties of these systems. During my PhD research project, I prepared epitaxial thin films of La-doped BaSnO3, a transparent conducting oxide (TCO) with the perovskite structure, which can be integrated in high-speed and multi-functional transparent devices due to its high room temperature electron mobility.
I am also experienced in analyzing highly complex multidimensional datasets characterizing ultrafast processes. This experience comes from my previous postdoc job where I was exposed to advanced fundamental research related to the understanding of the underlying physics of the insulator-to-metal phase transition observed in the strongly correlated VO2 material. The ultrafast data originated from time-resolved x-ray absorption spectroscopy (XAS) experiments on thin films of VO2 grown using PLD; and these were collected to disentangle the electron correlations (Mott-Hubbard) and the electron lattice interaction (Peierls) mechanisms associated with the phase changes.
Postdoctoral Researcher: Dr. Tulja Korukonda
My passion lies in renewable energy, with a particular focus on the materials and device physics of solar cells. This made me pursue a Master’s in Green Energy Technology (Pondicherry University) and a PhD in Energy Science and Engineering (from IIT-Delhi). At the Quantum Heterostructures and Device Physics Lab at LSU, my research is centered on developing stable perovskite inks for the commercialization of perovskite solar cells. I specialize in large-area coating methods such as roll-to-roll processing, blade coating, and slot-die techniques to create cost-effective and scalable solutions for perovskite solar cell manufacturing. My overarching goal is to contribute to clean and affordable electrification through my engineering and research expertise.
In my free time, I enjoy traveling, trekking, and volunteering for organizations that support animal welfare and sustainability

I have a Master of Science in Physics from Mahatma Gandhi University, Kerala. India. (2019-2021).
My current PhD project is on on 4d correlated electron systems; in particular, strontium ruthenate oxides of the Ruddlesden Popper phases. These systems exhibit complex interplay between the charge, spin, orbital and lattice degrees of freedom. We use thin films and heterostructures grown by Pulsed Laser Deposition (PLD) and Molecular Beam Epitaxy (MBE) of these materials to explore their unique magnetic/electronic properties in thin film samples as well as in devices.
