Assistant Professor
Ph.D, Physics, University Paris-Saclay & University of Central Florida 2011
Nicolas is originally from Paris, France, and is currently an Assistant Professor of Physics at the University of Central Florida. He earned his Ph.D. through a joint program between Université Paris-Saclay and UCF, and held a faculty position at Kennesaw State University from 2019 to 2023 before joining UCF in Fall 2023. His research focuses on the development of first-principles time-dependent quantum chemistry methods to study ultrafast electron dynamics in atoms and molecules, with particular emphasis on charge migration, strong-field physics, and attosecond spectroscopies. He leads a theory-focused research group developing first-principles simulations and theoretical approaches aimed at supporting and interpreting state-of-the-art ultrafast experiments. Outside of physics, Nicolas enjoys sailing, football and tennis, traveling, and spending time with friends and family.

Graduate Student
B. S., Physics, Colorado School of Mines 2022
Davis was born in Denver, Colorado, and obtained his B.S. degree from the Colorado School of Mines. His research centers on advanced high-order harmonic generation (HHG) schemes, including two-color UV+MIR configurations as well as MIR-only driving fields, with the goal of producing brighter, shorter, and more controllable X-ray attosecond pulses. In parallel, he explores HHG driven by optical vortex beams, which offer the possibility of generating attosecond pulses with novel spatiotemporal structures, and investigates the transfer of orbital angular momentum (OAM) from vortex light to excited circular Rydberg states of atoms. Outside of research, Davis enjoys cycling and climbing on the weekends.

Postdoctoral Researcher
Ph.D, Physics, Lousiana State University 2024
Kyle was born in Lafayette, Louisiana, and earned his Ph.D. from Louisiana State University, where he worked under the direction of Dr. Kenneth Schafer, Dr. Mette Gaarde, and Dr. François Mauger. His doctoral research focused on the initiation, characterization, and probing of ultrafast electron dynamics in molecules using time-dependent density-functional theory (TDDFT). Now at UCF, Kyle is working on the development of the time-dependent quantum chemistry method ATTOMESA and its applications to imaging charge dynamics in molecules using pump–probe schemes based on transient absorption spectroscopy (TAS) and high-harmonic spectroscopy (HHS). He also focuses on exploring new optical schemes with mid-infrared and ultrashort UV pulses for the generation of attosecond pulses via tabletop high-harmonic generation (HHG). In addition to his research, Kyle is teaching General Physics I at UCF in Spring 2026. In his spare time, he enjoys playing video games and writing.

B.S., Physics, University of Central Florida 2025
Jonathan was born in Miami, Florida, and recently earned his B.S. in Physics from the University of Central Florida. He completed his degree with a focus on computational physics, along with minors in mathematics and computer science. His research centers on a new spectroscopic technique known as Entangled Photoelectron Attosecond Spectroscopy (EPAS), which formed the basis of his undergraduate honors thesis, defended in Fall 2025. Outside of academics, Jonathan enjoys gymnastics and hiking.

M.S., Geosciences, The University of Montana 2025
Taylor grew up in Athens, Georgia, before moving to Marietta to study physics at Kennesaw State University. In our research group, he developed theoretical and computational tools to investigate strong-field ionization using Bohmian quantum trajectories. He was also involved in a collaborative project with experimentalists on circular dichroism in atomic resonance-enhanced few-photon ionization. After completing his studies at KSU, Taylor moved to Missoula, Montana, where he earned a Master’s degree in Geosciences at the University of Montana, focusing on glaciology. He enjoys hiking and camping and is currently continuing his academic journey as a Ph.D student in geophysics at the University of British Columbia in Vancouver.
B.S., Physics, Kennesaw State University 2024
Trevor grew up in Florida before moving to Marietta to study physics at Kennesaw State University. In our research group, he developed methods to analyze the orbital angular momentum (OAM) composition of high-order harmonics generated by the interaction of optical vortex beams with atomic gases. After completing his studies at KSU, Trevor moved to Ohio State University in Athens, where he is currently a Ph.D student in theoretical condensed matter physics, studying the properties of low-dimensional systems in the research group of Dr. Sandler.
B.S., Physics, University of Central Florida 2024
Sarah was born in Fairfax, Virginia, to a military family and grew up primarily in Niceville, Florida. While attending the University of Central Florida, she developed a strong interest in optics and atomic physics, graduating with a B.S. in Physics in 2024. In our group, Sarah contributed to studies of orbital angular momentum transfer to excited lithium atoms using optical vortex beams and its effects on photoelectron emission. She is currently pursuing an M.S. in Applied Optics at Delaware State University and is a member of the joint research group of Dr. Gour Pati and Dr. Renu Tripathi. Her current research focuses on millimeter-wave imaging systems using rubidium-85.
B.S., Physics & Photonics, University of Central Florida 2025
Braeden grew up just north of Orlando in Sanford, Florida, and obtained two bachelor's degrees in physics and photonic science and engineering at UCF. In our research group, he contributed to the development of the Entangled Photoelectron Attosecond Spectroscopy (EPAS) technique. After completing his studies at UCF, Braeden moved to the Ohio State University in Columbus where he is currently a Ph.D student working under the supervision of Dr. Kevin Singh, designing experimental quantum systems using laser-controlled neutral atoms. In his free time, he enjoys painting and hobby electronics.
