Research area keywords: high power laser development, high intensity laser-plasma interaction, table-top particle accelerators

Research profile on ResearchGate


In 2016, Nicholas received his bachelor’s degree in Physics (with highest honors) from Missouri University of Science and Technology while he competed on the NCAA track and cross country teams. Thereafter he attended the University of Michigan – Ann Arbor, where he is currently a doctoral student
in the Applied Physics department with embedded emphasis on plasma physics (Cert. Plasma Science and Engineering) and optics (M.Sc. Electrical Engineering).

He is part of the Center for Ultrafast Optical Science (CUOS) working under the advisership of Dr. Karl Krushelnick. His current projects include experimental and computational work on high intensity laser-plasma interactions for the next generation of table-top particle accelerators and radiation devices. In addition to this, Nicholas has an interest in the development of high power laser systems and has been
involved in design considerations for the ZEUS 3 PW laser.

Outside of the lab, Nicholas can be found running around Ann Arbor, backpacking in the mountains, playing overly complex boardgames, or drinking coffee after mass at St. Thomas the Apostle – Ann Arbor.

In 2022, Nicholas was selected as a Michigan Institute of Plasma Physics and Engineering (MIPSE) Fellow.

Rebecca Fitzgarrald

PhD Student, Applied Physics

Advisor: Alec Thomas, PhD

Office: 4116A ERB 1
Email: rfitzgar@umich.edu

Research area keywords: high-energy diagnostic development, multi-MeV photon production and measurement


Rebecca received her B.S. degree in both physics and math with honors from the University of Nebraska-Lincoln in 2020. Her research focused on atomic, molecular, and optical physics before making the switch to plasma physics at the start of graduate school. She is currently pursuing her PhD as part of the Applied Physics department under the guidance of Dr. Alec Thomas. Her current research focuses on the development of a high-repetition-rate gamma ray spectrometer for ZEUS, and she has worked with both gas targets and solid targets during experiments at a variety of laser facilities to study topics such as multi-MeV photon generation, nonlinear Compton scattering, and betatron radiation. 

Nicolas Kalem

PhD Student, Applied Physics

Advisor: Louise Willingale, PhD

Office: 4109 ERB 1
Email: nmontyk@umich.edu

Research area keywords: Direct laser acceleration of electrons, high intensity laser-plasma interactions, high rep-rate diagnostics for ZEUS

Nicolas received his B.A. in Physics with honors from University of California — Berkeley in 2023. During his four years there, he worked in a niche area of plasma physics, investigating antimatter behavior as part of the ALPHA experiment at CERN. 

In the fall of 2023 he began as an Applied Physics Ph.D. at the University of Michigan — Ann Arbor. Nicolas works with Dr. Louise Willingale in the realm of high intensity laser-plasma physics. His current work involves experimental and computational investigations into techniques for laser acceleration of electrons, as well as the development of diagnostics for ZEUS.

His academic interests are quite broad and extend beyond his immediate research. Outside of the lab, Nicolas enjoys swimming almost daily and playing volleyball.
