Nihal Jhajj, Postdoctoral Associate

Nihal studied physics and math at the University of Toronto, where he received his undergraduate degree in 2011, and received his PhD in physics (2017) from the University of Maryland . As a member of our group, he has studied laser filamentation and helped develop waveguides made from femtosecond filaments in air, which can possibly be used for guiding high power beams or collecting remote optical signals. Nihal's hobbies include homebrewing, cooking steaks, cycling , and lifting weights.

Sina Zahedpour, Postdoctoral Associate

Sina received his B.S. in electical engineering  (2008) at the Sharif University of Technology in Tehran, Iran and then his M. Sc. in electrical engineering in 2011 while at the University of Maryland. In 2017, he completed his PhD work in nonlinear optical measurements. While working in our group, Sina has studied laser filamentation in air, quantum effects in filamentation wakes, and nonlinear optical effects in intense laser fields. Sina enjoys both hiking and cycling.

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.


Fatholah Salehi, Graduate Student

Fatholah received his B.S. in physics (2010) from the Sharif University of Technology in Tehran, Iran and his M. 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.

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 hydrodynamics 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.


Anastasia Korolov, Graduate Student

Anastasia received her B.S. in Physics and Mathematics from Tufts University in 2017. Her former research experience focused on a diagonalization method for determining maximally negative energy states in quantum field theory. She also worked as a researcher for Tufts Institute of the Environment, where she developed a method for identifying interdisciplinary co-authorship among scientific researchers. In her free time, Anastasia enjoys writing fiction, playing RPGs, and learning gymnastics.

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.
