Institute for MEMS and VLSI Technology

The Institute for MEMS and VLSI Technology research at GWU is focused on using different technologies combined with pre- and/or post-processing steps. Several devices have been realized using CMOS technology, including RF MEMS devices, power sensors, SAW gas sensors, and many others. The research group uses CMOS to add active circuitry to the sensor, hence creating a complete system.  Learn more about Professor Zaghloul.

Computational Materials Science and Molecular Modeling Lab

The Computational Materials Science and Molecular Modeling Lab's current research focuses on several fundamental problems in computational materials science at nanometer scales, in particular, the surface and interfacial science problems. Research projects include the structure and dynamics of liquids under nanometer confinement, hydration force and hydrophobic interactions in aqueous system, the clay swelling mechanism, and nanotribology--the science of adhesion, friction and lubrication at nanometer scales. In collaboration with experimentalists, we are also working on the anti-fouling mechanism in water purification, the mechanical property of molecular junctions in molecular electronics devices, and nano-contact mechanics in the atomic force microscope. Learn more about Professor Leng.

Nanophotonics and Microfluidics Lab

The Nanophotonics and Microfluidics Lab's research interests focus on optofluidics, an emerging field integrating nanophotonics and microfluidics. On one hand, the microfluidic liquid manipulation enables novel nanophotonic properties not available with solid-state materials. For example, using this approach we have made one of the world's smallest liquid lasers on a chip. On the other hand, the on-chip integration of photonic and fluidic functions leads to highly compact and integrated biosensing devices, e.g. handheld blood analyzers. As a nascent field, optofluidics offers many opportunities awaiting exploration and holds great potential for helping realize the long-sought dream of integrated lab-on-a-chip systems.

Nanophotonics Lab

The Nanophotonics Lab research is investigating novel opto-electronics devices and energy-conversion solutions, primarily at nanoscale dimensions. We follow an interdisciplinary approach that draws expertise from electrical engineering, material science, and business technology management to address key questions such as next generation computing, high-efficient solar-conversion, and green-telecommunication. Our capabilities range from high speed opto-electronic device tests over rapid prototyping, to simulation analysis. Recent demonstrations include world's smallest laser and ultra-fast optical transistors for future photonic integrated circuits. Finally, our team is actively engaged in outreach and student learning programs.  Learn more about Professor Sorger.
