Areas of Research
Unmanned Aerial Systems and Flight Control Systems
Research on flight control systems for UAS focuses on the development of resource-aware fault-tolerant algorithms and their evaluation through flight testing on UAS. The goal of this program is to ensure the safe flight of aerial systems, under various abnormal flight conditions. Active research includes landmark (vision) based navigation, Virtual/Augmented reality and Natural Language-based interactions with drones, Machine Learning, as well as Artificial Intelligence/Machine Learning for UAS. This could involve simulating damaged aircraft to test fault tolerance, or simulating atmospheric conditions of Uranus and Neptune to examine possible aircraft designs for flight missions on outer planets. Research in UAS and Flight Control Systems is an integral part of the AI @ SLU Big Idea Initiative.

Modern electronics and modern delivery systems have enabled the use of very small spacecraft to achieve important science, exploration and technology demonstration missions. However, these new kinds of spacecraft face new obstacles to achieving mission success. At SLU, space systems research focuses on three areas: mission assurance of small spacecraft, development of new components for small spacecraft, and flight experiments in spacecraft autonomy.
Engineering education is an interdisciplinary field that includes collaborations between experts in engineering, education and psychology. Research in engineering education goes beyond improvements to engineering teaching by focusing on how people learn engineering and how to measure learning. Such research is well guided by specific research questions and hypotheses and ranges from engineering in K-through-12 to various topics related to undergraduate and graduate education and even industry applications. The current focus of Parks College is K-through-12 engineering education, which includes improving STEM pathways, math and science readiness, and engineering self-efficacy, along with the effects of experiential learning, service-learning, and collaborative learning on student retention and success at the college level. Parks has collaborations and funded work in this area with St. Louis Public Schools, KEEN, and Boeing.
Innovation and Entrepreneurship
To be an entrepreneur, students must possess four major aspects: technical competency, an understanding of customer needs, a sense of business and societal values. At Parks, we are not only creating curricular innovations to encourage our students to become entrepreneurs, but we are researching exciting facets of engineering entrepreneurship and entrepreneurship education. We are educating engineers to have the entrepreneurial spirit coupled with a strong business sense, forming future leaders with the technical and business knowledge to make an impact on the world.

Solid and Fluid Biomechanics
Biomechanics is the study of force, motion and strength (mechanics) applied to biological cells, tissues, organs and systems. Understanding how mechanics are applied to and affect living systems is the purview of biomechanics. From the study of how sports injuries occur and how bones break to that of cardiac muscle cell responses to force, all represent important biomechanics questions.
The most advanced cardiovascular flow emulator in the world is used to model healthy and diseased conditions in the human cardiovascular system, including the effects on the four chambers of the heart, coronary, cerebral, renal and peripheral perfusion. The effect of various prosthetic and assist devices is modeled experimentally and numerically. Current developments are in the definition of non-dimensional fluid mechanic hemocompatibility parameters. In addition to studying blood flow simulation in high shear, computation fluid dynamic simulations are being done on patient-specific models of pharyngeal airways, nasal airways, and aortic valve anatomies built from computer tomography (CT) scans, plus a few modeled valve geometries.
Tissue Engineering and Regenerative Medicine
Tissue engineering and regenerative medicine are rapidly growing, interdisciplinary fields that apply the principles and innovations of engineering and the life sciences to the development and restoration of tissues and organs. While similar, the two fields are often separated by their unique approaches. Tissue engineering is often identified by its aim to create tissue equivalents through a combination of tissue templates and scaffolds, mammalian cells and signaling systems. Regenerative medicine often utilizes the body’s own reparative capacity, enhanced through the application and manipulation of stem cells and growth factors, coupled with advanced rehabilitative technologies to restore tissue function. Typical targets for tissue engineering and regenerative medicine include skin, bone, muscle, cartilage, nerve, and other organs that necessitate repair and replacement. Other research involves musculoskeletal tissue engineering and rehabilitation, such as developing therapies for bone fracture healing and muscle regeneration following volumetric muscle loss. In terms of rehabilitation, electrical stimulation as a new approach to physical therapy following skeletal muscle injury and ultrasound-based therapy for the healing of bone fractures is also being investigated.

The focus is to conduct meaningful and applied research that leads to successful implementation to state and federal agencies standards.
Manufacturing and Materials
In Advanced Manufacturing, people use advanced technology to improve the manufactured products or manufacturing processes. This research area includes numerical and experimental investigation of machining (turning, milling, drilling, EDM, and welding) of difficult-to-machine materials, numerical and experimental investigation of laser peening processes of advanced materials, micro-machining and nano-machining of brittle materials and metallic materials, laser-assisted machining of brittle materials, nanosecond/femtosecond laser-matter interaction, robotics/mechatronics, monitoring and testing of manufacturing processes/failure of mechanical systems, automation of manufacturing processes using PLC and Industrial Robots, CAD/CAM.
Multifunctional materials are novel materials that couple multiple physical orderings. Examples include shape memory alloys, ferroelectric materials, ferromagnetic materials, thermoelectric materials and lithium ion batteries. These materials have motivated potential applications in actuators, sensors, energy harvesting, data storage, energy storage, micro-devices, among others. The macroscopic behaviors are determined by the underlying microstructures under specific physical and geometric compatibilities. Multi-scale simulations with molecular dynamics, phase field and finite elements are developed to investigate structure-property relations across multiple length and time scales, from which new materials can be designed computationally. Insights are provided for experiments, fabrications and applications.
The experimental facilities include Manufacturing System Laboratory, Mechatronics Laboratory, and Laser Peening Laboratory. Computer simulations are supported by supercomputing servers.
Safety is a process by which hazards are identified and their associated risks are understood. Good safety refers to the minimization of hazards or the comprehensive mitigation of risks. Perfect safety is improbable and impossible, as all activities involve a degree of risk. Consequently, organizations that are generally considered safe work proactively to seek out hazards and reduce their probability of operationalizing into an incident or accident.
Human Factors and Physiology
Human factors is the study of the interface in complex systems between the human and all other constituents. Influenced by human and system capabilities and associated limitations, human factors research at Parks College examines how the boundaries between humans and systems are simplified for ease of use and improved reliability. While maintaining the elements of more traditional human physiology human factors, researchers at Parks College focus on the interface of the human in the context of organizational relationships, and both their subtle and overt influence on safety culture.
The transportation engineering research program focuses on improving the safety and mobility of the surface transportation system for all road users and modes of transportation.
