Serious Researchers at Work
The Volgenau School of Engineering research centers focus on issues ranging from cybersecurity to artificial intelligence.
Each center is headed by a distinguished Volgenau School faculty member who harnesses the resources of the school as well as those of external sponsors to conduct a wide range of projects.
From investigating the relationship between brain structure, activity, and function from the subcellular to the network level at the The Center for Neural Informatics, Neural Structures, and Neural Plasticity (CN3) to analyzing data from crowdsourcing to predict outcomes at the C4I & Cyber Center, the school's researchers are working to solve a myriad of real-world challenges.
VSE doctoral students collaborate with faculty and contribute to the centers’ research by participating in sponsored projects, sharing their work at research conferences, and publishing articles and reports.

The Center for Configuration Analytics and Automation (CCAA) has been established under the National Science Foundation (NSF) Industry/University Cooperative Research Program (I/UCRC). The center is a multi-university and multi-industry consortium established and led by the University of North Carolina at Charlotte in partnership with George Mason University and a broad membership of industry and government organizations.
The goal of the Center is to build the critical mass of inter-disciplinary academic researchers and industry partners for addressing the current and future challenges of configuration analytics and automation to improve service assurability, security and resiliency of enterprise IT systems, cloud/SDN data centers, and cyber-physical systems by applying innovative analytics and automation.
The Center for Neural Informatics, Neural Structures, and Neural Plasticity (CN3) provides opportunities for cross-training in neuroscience, psychology, and engineering, both at the graduate and postdoctoral levels. Researchers investigate the relationship between brain structure, activity, and function from the subcellular to the network level.
The Center for Resilient and Sustainable Communities (C-RASC) is a transdisciplinary research center that addresses critical real-world problems through integrated approaches that build resilience. C-RASC’s vision is to support communities worldwide to create life-changing social and economic opportunities through locally-led, bottom-up resilience and sustainability initiatives supported by effective, replicable models. Distinguishing features of C-RASC include: concentrating on bottom-up, community-led approaches; addressing resilience in comprehensive and measurable ways; integrating the impacts and policy implications of converging, accelerating technological changes; and including practitioners with field experience. C-RASC also provides training opportunities for students, researchers, and practitioners, and oversees the global STAR-TIDES knowledge-sharing network.

The Learning Agents Center conducts fundamental and experimental research on the development of knowledge-based learning and problem solving agents. The center also supports teaching in the areas of intelligent agents, machine learning, knowledge acquisition, and artificial intelligence. Major research areas include instructable agents, multi-strategy learning and knowledge acquisition, domain modeling, knowledge representation and ontologies, cooperative problem solving, intelligent tutoring systems, and natural language processing.
The Rapid Prototyping Research Center (RPRC) focuses on providing its Department of Defense sponsors a unique perspective on rapid prototyping that aligns with Section 804 in the FY17 National Defense Authorization Act. Specifically, rather than developing a new system to satisfy intractable problems on the battlefield, the RPRC integrates new technology into existing infrastructure. This unique approach reduces acquisition costs since the sustainment tail is in place. It also reduces the time to field intractable solutions to the battlefield from 10-14 to 1-3 years and provides assurance that the prototype involved is integrated with the latest technology, not dated technology due to lengthy acquisition delivery timelines.
This lab is used to design and synthesize new composite nanomaterials, combining structured DNA nanoparticles with macromolecular assemblies of proteins, peptides, and lipids.

These new biomimetic nanoarchitectures also are used in the development of vaccines, delivery vehicles, and new materials for tissue engineering.

Chimeric Antigen Receptor (CAR) T-cell based immunotherapy has recently demonstrated significant potential against advanced stage cancers and other diseases. However, these treatments are lengthy, expensive, and only available to a limited population.
Researchers use a unique technique for synthesis and encapsulation of liposomes with tumor antigens, which can be delivered to stimulate t-cell expansion in vivo without the need to perform complex ex vivo genetic modification of cells.
In addition, we have also developed a robust lab-on-a-chip strategy to create hypoxic gradients within microfluidic devices to study mechanisms of tumor progression and acquisition of drug resistance. This platform also offers a novel and efficient way to perform pharmaceutical testing for personalized medicine.

This lab is part of the Center for Adaptive Systems of Brain Body Interactions (CASBBI). A key aspect of brain-body interactions is manifest in behavior. Perhaps the most ubiquitous example of this is the perception-action interactions that underlie motor behavior.
These interactions are constantly updated in response to experience—a process known as sensory-motor adaptation. Sensory-motor adaptation is critical for functioning successfully in one’s environment. The research methods pursued in this lab are broadly applicable to assistive technologies where physical systems, computational frameworks, and low-power embedded computing serve to augment human activities or to replace lost functionality.
Investigators examine experience-dependent changes that occur in both the intact and disordered sensory-motor system. Areas of study include the processes by which this adaptation occurs, its mechanisms, and relationships to functional disability and recovery. One focus within this group is the sensory-motor adaptation that occurs with motor practice in individuals with chronic hemiparetic stroke.
Another focus is the development and evaluation of novel bionic technologies such as upper extremity prostheses and hybrid exoskeletons, using wearable imaging sensors for sensing the human user’s volitional intent.
Addressing these issues requires a multimodal measurement approach that includes quantitative measurements of motor performance, muscle activation patterns and intramuscular architecture in health and disease, and corticomotor physiology, as well as standardized clinical assessments of impairment and function.

The equipment in this lab will enable us to perform precise friction and wear tests at temperatures up to 2000 sq. ft. In addition, we will explore new techniques to improve wear resistance of new materials (e.g., additively manufactured polymers/metals).
