Professor (Research) of Aeronautics and Astronautics and of Mechanical Engineering, Emeritus
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.

BioSimone D’Amico is Associate Professor of Aeronautics and Astronautics at Stanford University. He received the B.S. and M.S. degrees from Politecnico di Milano (2003) and the Ph.D. degree from Delft University of Technology (2010). From 2003 to 2014, he was research scientist and team leader at the German Aerospace Center (DLR). There, he gave key contributions to the design, development, and operations of spacecraft formation-flying and rendezvous missions such as GRACE (United States/Germany), TanDEM-X (Germany), PRISMA (Sweden/Germany/France), and PROBA-3 (ESA). From 2014 to 2020, he was Assistant Professor of Aeronautics and Astronautics at Stanford University. He is the Founding director of the Space Rendezvous Laboratory (SLAB), and Satellite Advisor of the Student Space Initiative (SSSI), Stanford’s largest undergraduate organization. He has over 200 scientific publications and 3000 google scholar’s citations, including conference proceedings, peer-reviewed journal articles, and book chapters. D'Amico's research aims at enabling future miniature distributed space systems for unprecedented science and exploration. His efforts lie at the intersection of advanced astrodynamics, GN&C, and space system engineering to meet the tight requirements posed by these novel space architectures. The most recent mission concepts developed by Dr. D'Amico are a miniaturized distributed occulter/telescope (mDOT) system for direct imaging of exozodiacal dust and exoplanets and the Autonomous Nanosatellite Swarming (ANS) mission for characterization of small celestial bodies. D’Amico’s research is supported by NASA, NSF, AFRL, AFOSR, KACST, and Industry. He is Chairman of the NASA's Starshade Science and Technology Working Group (TSWG). He is member of the advisory board of space startup companies and VC edge funds. He is member of the Space-Flight Mechanics Technical Committee of the AAS, Associate Fellow of AIAA, Associate Editor of the AIAA Journal of Guidance, Control, and Dynamics and the IEEE Transactions of Aerospace and Electronic Systems. He is Fellow of the NAE’s US FOE Symposium. Dr. D’Amico was recipient of the Leonardo 500 Award by the Leonardo Da Vinci Society and ISSNAF (2019), the Stanford’s Introductory Seminar Excellence Award (2019 and 2020), the FAI/NAA‘s Group Diploma of Honor (2018), the Exemplary System Engineering Doctoral Dissertation Award by the International Honor Society for Systems Engineering OAA (2016), the DLR’s Sabbatical/Forschungssemester in honor of scientific achievements (2012), the DLR’s Wissenschaft Preis in honor of scientific achievements (2006), and the NASA’s Group Achievement Award for the Gravity Recovery and Climate Experiment, GRACE (2004).
Edward C. Wells Professor of Engineering, Emeritus
BioProfessor DeBra collaborates with Stanford physicists on three projects: Gravity Probe-B (GP-B), Space Test of the Equivalence Principle (STEP), and the vibration isolation of a gravity-wave antenna (LIGO). These involve satellite control of attitude and translation and the development of instruments of extraordinary precision and accuracy. In GP-B gyroscopes were successfully orbited in 2004. They have been compared to stars to an accuracy approaching a nanoradian. In STEP the orbital performance promises improvements of a million in testing the equivalence of inertial and gravitational mass. (It is currently in a hiatus of funding.) Professor DeBra's interests in precision engineering extend to manufacturing where his students' work developing "quiet hydraulics" in the 1990s has more recently been applied to the vibration isolation of the optical systems of LIGO.

Current Research and Scholarly InterestsCharbel Farhat and his Research Group (FRG) develop mathematical models, advanced computational algorithms, and high-performance software for the design and analysis of complex systems in aerospace, marine, mechanical, and naval engineering. They contribute major advances to Simulation-Based Engineering Science. Current engineering foci in research are on the nonlinear aeroelasticity and flight dynamics of Micro Aerial Vehicles (MAVs) with flexible flapping wings and N+3 aircraft with High Aspect Ratio (HAR) wings, layout optimization and additive manufacturing of wing structures, supersonic inflatable aerodynamic decelerators for Mars landing, and the reliable automated carrier landing via model predictive control. Current theoretical and computational emphases in research are on high-performance, multi-scale modeling for the high-fidelity analysis of multi-physics problems, high-order embedded boundary methods, uncertainty quantification, probabilistic machine learning, and efficient projection-based model order reduction as well as other forms of physics-based machine learning for time-critical applications such as design, active control, and digital twins.
