Joseph Buchanan-Vega
Graduate Research Assistant

Joseph Buchanan-Vega earned a Bachelor of Science in Physics from Grambling State University in 2008. He then attended Louisiana Tech University and received a Master of Science in Physics (2010), and a Master of Science in Molecular Science and Nanotechnology (2011). While at Louisiana Tech University, his research was focused on material science: developing hard and fracture tough ceramics with the use of nanoparticles for applications like bullet proof vests. Joseph went on to teach physics in the Dallas area at a collegiate academy and in a traditional high school setting from 2010 to 2015. He then applied to and was accepted into the Electrical Engineering Ph.D. program at the University of Texas at Arlington.  He received the Louis Stokes Bridge to Doctoral Fellowship and was an active fellow in the program from 2015 to 2017. Joseph is a proud member of IEEE, NSBE, and Alpha Phi Alpha Fraternity.

Nasrin Razmjooei
Graduate Research Assistant

Nasrin earned a Bachelor of Science in Physics from Valiasr University in 2010. She then attended Shiraz University and received a Master of Science in Optics and Lasers (2013). She was accepted as a research assistant at Universtiy of Victoria, BC, Canada in 2017. For her bachelor studies, she worked on simulation of energy levels in solid-state lasers such as Nd:YAG. As a master student at Shiraz University, she was intrigued in pursuing her research in photonics; her research project was related to simulation and design of optical waveguides for label-free biosensing application. She also worked on designing energy levels of solid-state lasers. Nasrin obtained nanofabrication experience including advanced lithography, scanning electron microscope, and focused ion beam at University of Victoria. In addition to research, Nasrin has experience teaching, having taught physics courses both in university and high school. She is currently completing her PhD in Electrical Engineering at University of Texas at Arlington. Her main focus is on Nanophotonics, Nonlinear Optics, and Laser and Pure Electromagnetics. She is an active member of Optical Society of America (OSA), the International Society for Optics and Photonics (SPIE), and IEEE.
