BioProfessor Chang's primary research interest is in the areas of multi-functional materials and intelligent structures with particular emphases on structural health monitoring, intelligent self-sensing diagnostics, and integrated health management for space and aircraft structures as well safety-critical assets and medical devices. His specialties include sensors and sensor network development, built-in self-diagnostics, integrated diagnostics and prognostics, damage tolerance and failure analysis for composite materials, and advanced multi-physics computational methods for multi-functional structures. Most of his work involves system integration and multi-disciplinary engineering in structural mechanics, electrical engineering, signal processing, and multi-scale fabrication of materials. His recent research topics include: Integrated health management for aircraft structures, bio-inspired intelligent sensory materials for fly-by-feel autonomous vehicles, active sensing diagnostics for composite structures, self-diagnostics for high-temperature materials, etc.

BioProfessor Cantwell's research interests are in the area of turbulent flow. Recent work has centered in three areas: the direct numerical simulation of turbulent shear flows, theoretical studies of the fine-scale structure of turbulence, and experimental measurements of turbulent structure in flames. Experimental studies include the development of particle-tracking methods for measuring velocity fields in unsteady flames and variable density jets. Research in turbulence simulation includes the development of spectral methods for simulating vortex rings, the development of topological methods for interpreting complex fields of data, and simulations of high Reynolds number compressible and incompressible wakes. Theoretical studies include predictions of the asymptotic behavior of drifting vortex pairs and vortex rings and use of group theoretical methods to study the nonlinear dynamics of turbulent fine-scale motions. Current projects include studies of fast-burning fuels for hybrid propulsion and decomposition of nitrous oxide for space propulsion.

BioProfessor Christensen's research is concerned with the mechanics of materials. The behavior of polymers and polymeric fiber composites are areas of specialization. Of particular interest is the field of micro-mechanics that focuses on materials' functionality at intermediate-length scales between atomic and the usual macro scale. Applicable techniques involve the methods of homogenization for all types of composite materials. The intended outcomes of his research are useful means of characterizing the yielding, damage accumulation, and failure behavior of modern materials. A related website has been developed to provide critical evaluations for the mathematical failure criteria used with the various classes of engineering materials. Most of these materials types are employed in aerospace structures and products.

BioProf. Close's research involves space weather detection and modeling for improved spacecraft designs, and advanced signal processing and electromagnetic wave interactions with plasma for ground-to-satellite communication systems. These topics fall under the Space Situational Awareness (SSA) umbrella that include environmental remote sensing using satellite systems and ground-based radar. Her current efforts are the MEDUSSA (Meteoroid, Energetics, and Debris Understanding for Space Situational Awareness) program, which uses dust accelerators to understand the effects of hypervelocity particle impacts on spacecraft along with Particle-In-Cell simulations, and using ground-based radars to characterize the space debris and meteoroid population remotely. She also has active programs in hypersonic plasmas associated with re-entry vehicles.

BioI am a first year graduate student in the Department of Aeronautics and Astronautics at Stanford University. With a passion for science and technology, I seek to explore opportunities where I am immersed in an environment that nurtures academic excellence and ground breaking research. I am an aerospace enthusiast with a focus on the use of design optimization strategies to develop new air-frame configurations that seamlessly integrate next-gen propulsion systems. In addition, I am keen on studying the application of composite, flexible surfaces that tailor lift distribution on flying wings.
I graduated Summa Cum Laude from Howard University with a Bachelor’s Degree in Mechanical Engineering. In undergrad, my involvement in extracurricular activities nurtured an ability to share information and contribute to decision-making. Outside coursework, I participated in global collaborative competitions geared towards proposing innovative solutions for future transportation. I also led humanitarian missions to Kenya, El Salvador and Haiti with Engineers Without Borders, a non-profit organization that partners with developing communities worldwide to improve their quality of life. These partnerships involved the implementation of sustainable engineering projects such as power, communal infrastructure and access to drinking water.
I am a member of Tau Beta Pi, the Engineering Honor Society; the American Society of Mechanical Engineers (ASME); the American Institute of Aeronautics and Astronautics (AIAA), and the National Society of Black Engineers (NSBE).
Following graduate school, I plan to pursue a career in industry focused on research and development of revolutionary air and spacecraft technology. My future aspirations also include teaching and inspiring minority students in STEM.
