"The focus of the lab is on tribology (science of lubrication, wear, and friction) and contact and interfacial mechanics at different scales. The pivot of the research is centered around the performance of advanced materials and components such as superalloys as well as additively manufactured parts under extreme environments."

Experts in our laboratories are working to develop more energy-efficient systems, reduce wear on critical components, synthesize new nanomaterials, improve health care, and enable advanced water treatment.

The mechanical engineering laboratories have state-of-the-art infrastructure and equipment. This is what each team says about their work:

Vessel Dynamics Laboratory capitalizes on George Mason University’s unique waterfront facility at the Potomac Science Center.  The research team’s focus is on computational and experimental studies to better understand the dynamics and hydrodynamics of manned and unmanned vessels.  Principal investigator: Leigh McCue.

Micro/Nano Mechanics and Photonics with Nanomaterials Laboratory, also called the Kang Lab, conducts fundamental research on micro/nanoscale mechanics and photonics with nanomaterials for innovations in nanobiosensors. Researchers explore broad fields including nanophotonics, optofluidic, optoelectronics, and plasmonics to create innovations in advanced materials and manufacturing for high-performance, low-cost sensor devices. The research aims to develop advanced, high-performance materials with new functionalities in mechanical, optical, and electrical properties. Principal investigator: Pilgyu Kang.

Nano/micro-scale Transport Engineering Laboratory investigates the fundamental physics underlying nano and microscale transport phenomena in fluids, especially involving interfaces and electric fields. The work will enable design of better sustainable energy systems, more energy-efficient and affordable wastewater treatment methods, and even improved treatments for diseases like cancer. Principal investigator: Jeffrey Moran.

Tribology and Surface Mechanics Lab investigates surface and interfacial mechanics as well as friction and wear phenomena from nano to macro scales. The research seeks to reduce energy and material consumptions in systems with moving components operating especially at harsh environments (e.g., very high temperatures). The equipment in this lab will enable researchers to perform precise friction and wear tests at temperatures up to 2000 ºF. In addition, the scientists will explore new techniques to improve wear resistance of new materials (e.g., additively manufactured polymers/metals). Principal investigator: Ali Beheshti.

Dong Group has strong interests in the following areas: advanced materials synthesis (nanomaterials, polymer, and their hybrid and hierarchical composites); advanced materials enabled energy devices (flexible solar cells and integrated energy devices); advanced material enabled water treatment technologies (water desalination and water decontamination). Researchers are also working on multiple interdisciplinary topics. Principal investigator: Pei Dong.

Computational Hemodynamics Lab investigates the role of hemodynamics (blood flow) in cerebrovascular diseases. In particular, 3D image-based computational fluid dynamics is used to model blood flows in cerebral arteries on a patient-specific basis. The focus of our research is mainly on cerebral aneurysms and ischemic strokes. Principal investigator: Juan Raul Cebral.

“Water and energy systems are intricately interconnected. Our research interests lie in the areas of materials design, advanced manufacturing, and device fabrication to address the integrated challenges around the energy nexus.”
