Andy Goers, Postdoctoral Researcher

Dr. Goers earned a degrees in physics and mathematics from Iowa State University in 2010 and

joined Professor Milchberg’s group the same year.  He defended his Ph.D. dissertation, “Electron

Acceleration by Femtosecond Laser Pulses in Micro-Structured Plasmas,” in November 2015.  Andy is currently working on a variety of laser driven particle acceleration experiments in the lab.  In his free time, Andy is an avid soccer player and enjoys following his beloved Chicago Cubs.

George Hine, Graduate Student

After earning a B.S. in both chemical engineering and physics at Rutgers University, George came to study physics at the University of Maryland in 2010. He has supported the group's research in laser based particle acceleration, including extensive computation modeling with the particle-in-cell (PIC) code TurboWAVE and creating spatially modulated plasma waveguides using interferometry. His hobbies include (but are certainly not limited to) oil painting, multi instrumental roles in a band with fellow physics graduate students: Rayleigh-Jeans and the Ultraviolet Catastrophes, and snowboarding.

Sina Zahedpour, Graduate Student

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. 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.

Nihal Jhajj, Graduate Student

Nihal studied physics and math at the University of Toronto, where he received his undergraduate degree in 2011. 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.

Eric Rosenthal, Graduate Student

A native of Montgomery county, Eric attended received both his B.S. in physics (2010) and  his M. Sc. in physics (2015) from the University of Maryland. During his time in our group, Eric has studied laser filamentation in air, filament energy deposition, and the creation of transient air waveguides. Beyond being a labview extraordinaire, Eric's hobbies include electronics, chess, snowboarding, and riding his motorcycle.

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 spectrometry 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 first year, he has been involved in the research on laser based particle acceleration. Outside of lab work, Daniel enjoys camping and hiking, rock climbing, singing, and Scouting.

Undergraduate Students

Dan Younis

Howard Milchberg, Principal Investigator

Professor Milchberg received his B. Eng. in engineering physics from McMaster University in 1979 and a Ph.D. in astrophysical sciences from Princeton University in 1985.  He has been affiliated with the University of Maryland since 1988. Professor Milchberg is the winner of an NSERC Postgraduate Fellowship, National Research Council of Canada (1979-1984); NSF Presidential Young Investigator Award (1988); and the APS John Dawson Award for Excellence in Plasma Physics Research (2005)  He was elected a fellow of the American Physical Society, Division of Laser Science (1995) and a fellow of the Optical Society of America (2013).

Jared Wahlstrand, Associate Research Scientist

Dr.  Wahlstrand received a B.A. in physics and mathematics from Carleton College in 1999.  He received a Ph.D. in applied physics from the University of Michigan in 2005, where he studied ultrafast excitation of THz radiation and sound, coherent optical phonons, and electronic excitations in semiconductor quantum wells. Dr. Wahlstrand came to our group in 2009 and has since performed fundamental experiments of nonlinear optics in atoms and molecules under intense laser fields.  His  interests include nonlinear optics and coherent control. Dr. Wahlstrand was a National Research Council postdoc at JILA/National Institute of Standards and Technology in Boulder, CO, where he worked on quantum noise in femtosecond frequency combs and the multiphoton Franz-Keldysh effect.
