Justin Crabb

Biography

Justin Crabb received his B.S. degree in Electrical Engineering (Signals, Communications, and Controls) at the University of Houston in 2017.  His final research project was on active radar scattering cancellation which involved an array of antennas to cancel the reflections from scattered incident waves.  He received his M.S. degree in the Department of Electrical Engineering at the University at Buffalo, The State University of New York under the guidance of Josep Miquel Jornet. He has worked as a Teaching Assistant and Research Assistant since 2018.  In fall of 2019 Justin transferred with his research team and faculty advisor to Northeastern University to continue his Ph.D.

In 2016 he joined Jacobs Engineering as an electrical engineering intern, focusing on computer-aided design for consulting. Following in 2017, he worked as a start-up designer for a MakerSpace lab at the University of Houston to introduce prospective students into electrical engineering and taught a few introductory-level workshops on microcontroller units. In 2022 he performed research as a visiting Ph.D. student on graphene- and black phosphorus-based FET detectors using the photothermal-electric effect at the Nanoscience Institute of the National Research Council (NEST Lab) under Dr. Vitiello.

His research interests include wireless communication systems and plasmonic devices for THz band communications using high-electron mobility FETs with 2D materials such as graphene and black phosphorus.

Research

Development of a multi-physics simulation platform for hybrid graphene/black phosphorus/III-V-based plasmonic FET devices for on-chip THz signal generation, detection, modulation, and amplification. Numerical modeling of the photothermal electric effect and plasmonic instabilities such as the Dyakonov-Shur instability in 2DEG channels to study plasmonic oscillations in the THz band using the discretization of Maxwell’s equations through the finite-difference time-domain method, the hydrodynamic model, and thermoelectric equations.
