He obtained both his M.Sc. and Ph.D. degrees from Stanford University, where he was awarded the Ballhaus prize for best thesis in the Department of Aeronautics and Astronautics. He was a keynote speaker at the International Forum on Aeroelasticity and Structural Dynamics in 2007 and the Aircraft Structural Design Conference in 2010. He has received the Best Paper Award in the AIAA Multidisciplinary Analysis and Optimization Conference four times (2002, 2006, 2012, and 2014). He is a member of the AIAA MDO Technical Committee and was the technical co-chair for the 2008 AIAA Multidisciplinary Analysis and Optimization Conference. He has served as Associate Editor for the AIAA Journal, and is currently an Associate Editor for the Journal of Aircraft, Optimization and Engineering, and Structural and Multidisciplinary Optimization.

Lecture Title: 
Aircraft Wing Design via Numerical Optimization: Are we there yet?
Wing shape is a crucial aircraft component that has a large impact on its performance. Wing design optimization has been an active area of research for several decades, but achieving practical designs has been a challenge. One of the main challenges is the wing flexibility, which requires the consideration of both aerodynamics and structures. To address this, we proposed the simultaneous optimization of the outer mold line of a wing and its structural sizing. The solution of such design optimization problems is made possible by a framework for high-fidelity aerostructural optimization that uses state-of-the-art numerical methods. This framework combines a three-dimensional CFD solver, a finite-element structural model of the wingbox, a geometry modeler, and a gradient-based optimizer. This framework computes the flying shape of a wing and is able to optimize aircraft configurations with respect to hundreds of aerodynamic shape and internal structural sizes. The theoretical developments include coupled-adjoint sensitivity analysis, and an automatic differentiation adjoint approach. The algorithms resulting from these developments are all implemented to take advantage of massively parallel computers. Applications to the optimization of aircraft configurations demonstrate the effectiveness of these approaches in designing aircraft wings for minimum fuel burn. The results show optimal trade-offs with respect to wing span and sweep, which was previously not possible with high-fidelity models.

Lecture topic: A NASA Langley Perspective on Space Technology – Driving Success Through Collaboration
The term “Space Technology” encompasses a wide range of capabilities needed to provide efficient access to space, mobility while in space, and the ability to live in space based on mission requirements.  In recent NASA terms, this is termed the “Technology Path to Pioneering Space” where we will Go, Land, and Live.
At the Agency level, Space Technology encompasses topics like:
High Power Solar Electric Propulsion
Mars Entry Descent and Landing Systems
Lightweight Space Structures
At the field centers, we match up our expertise to work these topics, both with other NASA centers as well as with industry and academia.  At NASA Langley, we have been proactive in developing our space technology thrust areas that best match up our expertise with the needs of NASA’s Space Technology, Exploration, and Science Mission Directorates.  In addition, we believe there is great value to our Agency in collaborating and developing partnerships with industry and academia that meet the needs of all parties.  Working together drives innovation, produces results more quickly, and provides an infusion path for NASA missions, a commercialization path for industry for their customers, and robust research opportunities for universities.
The thrust areas we currently focus on at NASA Langley are Entry, Descent, and Landing; Lightweight Transportation Systems; In-Space Assembly and Manufacturing; and Habitation Systems.  Entry Descent and Landing technologies permit more capable science and access to other planets or bodies for both humans and spacecraft (including equipment).  At NASA Langley, this includes hypersonic aerodynamic decelerators, advanced materials for thermal protection, retro-propulsion, and instruments and sensors.
Lightweight Transportation Systems is mostly focused on reducing mass to allow more carrying capability per launch.  This includes reducing the mass of launch vehicles through the use of composites, nano-materials, and other lightweight materials.
In-space assembly involves developing advanced concepts and enabling technologies for the assembly of very large structures.  This includes joints and joining (manual and robotic), jigging robots, e-beam welding and additive manufacturing, long reach robotic arm manipulation, and autonomous control.
Our focus for habitation systems is advanced structures and materials including composites, nano-materials and inflatables.  We are also focusing on radiation protection.  This radiation work includes the analysis of radiation environments and the use of prototypes to explore system configurations to reduce and minimize astronaut risk.
In summary, Space Technology is a very broad and somewhat imposing topic with many challenges.  By focusing our efforts based on our expertise and combining this with others through collaboration and partnerships, NASA Langley is addressing difficult problems and impacting the future of space travel.
Mr. Don Farr
Boeing Research & Technology 
Mr. Don Farr is a Technical Fellow for Boeing Research and Technology Support and Analytics Integrated Technology Team in Huntsville, Alabama.  He is working on advanced technology in Model Based System Engineering applied to the digital thread throughout the life cycle of platform development, shifting the emphasis in design to account for the manufacture and assembly of the products. 
Don has over 25 years with The Boeing Company working on various programs and projects.  He started his career on the Comanche program in Philadelphia with avionics and embedded sensors in the composite structures.  After 10 years on the Comanche program, leading many development and integration efforts (including first flight), Don began work on the newly defined Network Centric Operations Thrust in St. Louis Missouri.  He spent the next 5 years developing and integrating System-of-System technologies that enabled the integration of dozens of platforms (F-15, A/F-18, Apache, Tanker, and the like).
Don’s first assignment in Huntsville was developing and integrating an advanced discrimination technology into the Missile Defense architecture.  This technology spurred significant changes to the radar, Command and Control, and Ground-Based Mid-course Defense fire control systems, including the interceptors.
Don earned his Bachelor of Science in Electrical Engineering at Lamar University in Beaumont, Texas.  He went on to complete an advanced degree in Electrical Engineering at the University of Delaware in Newark.
Lecture topic: Automation in the Aerospace Industry
Aerospace manufacturing is a complex production system with millions of parts, thousands of suppliers, and more than 150 countries. Automation plays a major role not only in manufacturing, but in the design and post production phases as well. 
• In Model-Based System Engineering (MBSE) is where the full spectrum of requirements are analyzed and incorporated. 
• In the generation of 3D Model Based Definition (MBD) of parts and assemblies 
• In the manufacturing and inspection of parts, wiring, and structures (solid and composite) 
• In the assembly of systems, subsystems, and structures into the final product 
As manufacturers apply automation throughout the life cycle of the platform, the ability to monitor and adjust processes to maximize efficiency is critical to the bottom line. Data Analytics is playing an ever increasing role in manufacturing automation. 
The Boeing Company has many commercial and military platforms in design and production that rely heavily on automation within the life cycle. Each platform provides its own set of automation challenges to increase the efficiency of development and production. This presentation provides some insight into how Boeing is leveraging automation and the critical role it will play in the company’s future.
