Sc. in physics (2012) from the University of Central Florida before coming to his PhD program in chemical physics at Maryland. In previous research, he has studied confocal absorption microscopy, dissociative recombination of molecular ions, and aerosols. In our group, he has contributed to research on laser based particle acceleration, including fabrication and characterization of gas jet targets and computational modeling using the particle in cell (PIC) code TurboWAVE. In his free time, Fatholah enjoys reading Farsi literature, camping, hiking, biking, and horseback riding.

Bo Miao, Graduate Student

Bo received a  B.S. in physics from the University of Science and Technology of China in 2013, before coming to the University of Maryland physics department. In Fall 2015, he was the recipient of the department's Richard and Anna Iskraut Scholarship. While in our group, Bo has worked on laser plasma acceleration, as well as femtosecond pulse spectroscopy and characterization. Bo's interests outside of physics include piano, cycling and soccer.

Ilia Larkin, Graduate Student

Ilia completed his B.S. in physics at the Georgia Institute of Technology in 2013, where he was involved in research with the Georgia Tech Cluster Beam Lab. Since coming to the University of Maryland, Ilia has become an active part of our experiments on femtosecond filamentation in air. He is also an avid photographer, and we can thank him for many of the impressive photos of our lab highlighted on the website.

Linus Feder, Graduate Student

After finishing his B.A. at St. John's College in Annapolis in 2012, Linus followed his passion for science to complete a B.S. in physics University of Maryland in 2014. As an undergraduate, he joined the intense laser-matter research group and has been studying laser based plasma acceleration. Linus enjoys square dancing, the eternal search for truth, and local band Rayleigh-Jeans and the Ultraviolet Catastrophe.

Daniel Woodbury, Graduate Student

Daniel graduated from Brigham Young University with a B.S. in physics (2015) before coming to study at the University of Maryland. He is a recipient of the NNSA Stewardship Science Graduate Fellowship, and also received an honorable mention in the NSF Graduate Fellowship program. While at BYU, he conducted research on ultracold neutral plasma and ultracold atoms. He has also completed research internships in plasma waves and laser target heating while at the Princeton Plasma Physics Laboratory and Sandia National Laboratories. During his time here, he has been involved in the research on laser based particle acceleration using mid-IR drivers, and avalanche ionization. Outside of lab work, Daniel enjoys camping and hiking, rock climbing, singing, and Scouting.

Robert Schwartz, Graduate Student

Robert Schwartz received his BA in physics and mathematics from Cornell University in 2012 where he worked at the Cornell Electron-Positron Storage Ring studying electron cloud build-up and mitigation. He went on to study biophysics with a focus on imaging and microscopy techniques at University of California, San Diego, receiving his M.S. in physics and the Excellence in Physics award. Robert joined the lab in Fall 2016 and has specialized in designing new gas jet targets for laser plasma acceleration. Outside the lab, Robert enjoys jazz and woodworking.


Scott Hancock, Graduate Student

Scott received his B.S. in International Affairs and Economics from the Georgia Institute of Technology in 2008. In 2017, he completed his M.S. in Engineering Physics at Appalachian State University.  He was a recipient of the North Carolina Space Grant Graduate Fellowship in 2016. At the Biophysics and Optical Sciences Facility at Appalachian State University he worked on automation  of laser tweezers, Raman spectroscopy systems, and temperature determination of optically trapped particles.  Scott also worked for the Center for Analytics, Research and Education at Appalachian State University studying internal and external factors effecting technology transfer performance in universities. Outside of lab, Scott enjoys camping, hiking, biking, and cooking.

Jaron Shrock, Graduate Student

Jaron earned a BA in Physics and Mathematics with High Honors from Swarthmore College in 2018. While there, he worked on Taylor state plasmas on the Swarthmore Spheromak Experiment, studying equations of state and developing pulsed power acceleration systems. Outside the lab, Jaron's interests include fly fishing, music, and cooking.

Manh Le, Graduate Student

Manh received a BS in Physics from Ohio State University in 2018. His undergraduate research at Ohio State focused on short pulse lasers and ultrafast laser-matter interactions. He also worked with the extreme light lab at AFRL, studying target-normal sheath acceleration using particle-in-cell simulations. Outside of the lab, Manh enjoys learning languages, baking, and Dungeons and Dragons.

Andrew Goffin, Graduate Student

Andrew received his B.S. in electrical engineering (2017) from the University of Maryland, College Park, graduating summa cum laude, and joined the graduate program for electrical engineering the following fall. During his undergraduate education, Andrew worked at NIST on the AC Josephson Voltage Standard, characterizing the response of the system and automating experiments. Andrew's focus in the lab has been on femtosecond filamentation in the air and its applications. Besides lab work, Andrew enjoys collecting records and going to concerts.

Lucas Railing, Graduate Student

Lucas received his Bachelor's in physics from Washington and Jefferson College in 2016. His undergraduate research focused on light scattering in biological tissue for applications in photodynamic therapy. After graduating, he worked at Vitro Architectural Glass to improve mechanical durability measurements of window coatings using image processing techniques in Python. He then studied supercontinuum generation in dispersion varying waveguides at the University of Connecticut before receiving his M.S. in 2019. Outside of the lab, Lucas enjoys hiking, biking and swimming.
