Alan M. Title (NAS/NAE) is a senior fellow at the Lockheed Martin Space Systems Advanced Technology Center (ATC) in Palo Alto, CA. His primary scientific research interest is the generation, distribution, and effects of the solar magnetic field throughout the Sun’s interior and outer atmosphere. At present, he has 169 articles in refereed journals. He is currently the Principal Investigator for NASA’s solar mission called the Interface Region Imaging Spectrograph (IRIS). Title was the Principal Investigator responsible for the Atmospheric Imaging Assembly on NASA’s Solar Dynamics Observatory (SDO) launched in 2010, and is a Co- Investigator for another instrument on SDO, the Helioseismic Magnetic Imager. He was also the Principal Investigator for NASA's solar telescope on the Transition Region and Coronal Explorer (TRACE) mission, launched in 1998, and the Focal Plane Package on the JAXA/ISAS Hinode mission launched in 2006. Additionally, Title serves as a Co-Investigator responsible for the Michelson-Doppler Imager (MDI) science instrument on the NASA-European Space Agency Solar and Heliospheric Observatory (SOHO), launched in 1995. All of these instruments were built under Alan Title’s direction at the ATC. As an engineer, Alan Title designs, develops, builds, and flies new instruments that will gather the data necessary to inform his solar research interests. He led the development of tunable bandpass filters for space-based solar observations, a version of which is currently operating on the JAXA/ISAS Hinode spacecraft. He also invented a tunable variation of the Michelson Interferometer that has been employed on the SOHO spacecraft, the Solar Dynamics Observatory (SDO), the Global Oscillations Network Group of the National Solar Observatory as well as other ground-based systems. Outside of his research. Dr. Title has supported activities at the Tech Museum, Chabot Observatory, Boston Museum of Science, the National Air and Space Museum, and the Hay- den Planetarium. In addition, his educational outreach funding has supported a yearly summer program for Stanford undergraduates, and the Stanford Hass Center activities that develop science programs for K-12 classrooms. And for two decades, promising students from the Palo Alto High School District have come to work in his laboratory. Among his honors and awards are the 2011 John Adam Fleming Medal, awarded not more than once annually to an individual “for original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and related sciences.” He received his Ph.D. in Physics from the California Institute of Technology. Most recently, he has served on the NRC’s Board on Research Data and Information and the NASA Technology Roadmap: Instruments and Computing Panel.

David M. Van Wie is the chief technologist of precision engagement at the John Hopkins University Applied Physics Laboratory (JHU/APL) Precision Engagement Mission Area with responsibility for identifying, maturing, and developing innovative technologies in the areas of fluid dynamics; structural sciences; detection system information fusion; signal and information processing; guidance, navigation, and control; command and control instrumentation and analysis; and radio frequency technologies. Dr. Van Wie also holds a research faculty position in the Department of Mechanical Engineering at JHU and lectures in the Department of Aerospace Engineering at the University of Maryland in the areas of space propulsion, aerodynamics, and high-temperature gas dynamics. He has served as a member of the United State Air Force Scientific Advisory Board (SAB), where he conducted studies on hypersonic systems, small precision weapons, virtual training technologies, future launch vehicles, and munitions for the 2025+ environment, and served as the vice chair and chair for the 2010 and 2011 AFRL Science and Technology Reviews, respectively. Dr. Van Wie was elected a fellow of the American Institute of Aeronautics and Astronautics (AIAA) in 2010. He attended the University of Maryland and received B.S., M.S., and Ph.D. degrees in aerospace engineering. Dr. Van Wie has served on several NRC committees, including the Committee on Conventional Prompt Global Strike Capability, the Steering Committee on the Decadal Survey of Civil Aeronautics, the Committee on Future Air Force Needs for Survivability and he chaired the Committee for the Reusable Booster System Review and Assessment.
