Lindsey is one of four finalists from Ph.D.-granting institutions in North America. The CRA Outstanding Undergraduate Researcher awards recognizes students who show outstanding research potential in an area of computing research.</p> <p>Lindsey is recognized for his research in motion planning and its applications in studying molecular motions. In particular, his research dealt with studying how we might be able to adapt techniques first developed for robot motion planning to improve "decoy sets" used in developing energy functions that are used in protein structure prediction algorithms.</p> <p>Lindsey's work developed a new method to evaluate and improve the quality of decoy databases by adding novel structures and/or removing redundant structures. He tested the approach on different decoy databases of varying size and type and showed significant improvement across a variety of metrics. This work potentially has great impact since predicting protein structures and simulating protein folding motions are two of the most important problems in computational biology today.</p> <p>Dr. Nancy M. Amato, Unocal Professor in the Department of Computer Science and Engineering at Texas A&amp;M University, is his faculty mentor. He also worked closely with Dr. Shawna Thomas, a TEES assistant research scientist in CSE</p> <p>"I am very impressed with him in all aspects — he is overall one of the best students I have worked with in my career," said Amato,, who nominated Lindsey for the award. "In addition to being really smart and an efficient worker, Aaron is also a leader and good citizen."</p> <p>Commenting on his success, Lindsey said, "I am blessed to have such great mentors and colleagues."</p> <p>In 2014 Lindsey co-authored two research papers: "Improving Decoy Databases for Protein Folding Algorithms" with Hsin-Yi Yeh, Chih-Peng Wu, Shawna L. Thomas, and Amato, that was published in a workshop associated with the ACM Conference on Bioinformatics, Computational Biology, and Health Informatics, and "UMAPRM: Uniformly Sampling the Medial Axis" with Hsin-Yi Yeh, Jory Denny, Shawna L. Thomas, and Nancy M. Amato that was published in the IEEE International Conference on Robotics and Automation, which is the flagship conference of the IEEE Robotics and Automation Society. His senior thesis was "Improving Decoy Databases for Protein Folding Algorithms."</p> <p>His many honors and awards include the 2014 CRA Outstanding Undergraduate Researcher Honorable Mention Award and scholarships from Aggieland Bound and the CSE Industrial Affiliates Program. Lindsey was a member of the ACE Scholars Program, the CSE honors program, and a dedicated peer teacher in the CSE department. He was awarded membership in the Phi Eta Sigma Honor Society for earning a GPA of at least 3.5 during his first year of college, and he was the technology chair for Texas A&amp;M's Honors Student Council. In December 2014, Lindsey graduated with a 3.92 GPA and a bachelor's degree in computer science. He is planning on working for a bit before he returns to graduate school.</p> <p>This year's CRA Outstanding Undergraduate Researcher Award program was sponsored by Microsoft Research.

I am glad that the partnership with Qatar University, QEERI, and QAPCO — along with other organizations — allowed us to host such an international meeting.”</p> <p>This materials congress focuses on new materials research and development in applications of interest for Qatar and the entire Middle East and Mediterranean region. The goal of this congress is to build synergy among researchers working on different materials applications but with similar objectives of enhancing design, sustainability, and functionality of materials. The event is also a forum for establishing collaboration among academia, research institutions, and industry in the Middle East and Mediterranean region and the rest of the world.</p> <p>Dr. Mohammed Yousef Al Mulla, vice president and CEO of QAPCO, welcomed all the delegates to the conference, saying, “QAPCO is honored to be one of the corporate sponsors of this important conference as we believe now is the perfect time to highlight the current research and development being undertaken in this field. It is indeed a privilege to be able to work in partnership with Texas A&amp;M University at Qatar as it provides a wonderful opportunity for industry and academia to collaborate in order that the theoretical aspects discussed at conferences like this can be successfully applied within production.”</p> <p>The three-day event includes three concurrent sessions on each day that align with the three topical tracks: Sustainable Infrastructure Materials; Materials for Energy Extraction, Conversion, and Storage; and Computational Materials Design. Track 1 encompasses materials issues and solutions pertaining to critical infrastructure and will have an overarching theme of sustainability. In track 2, there is an emphasis on not just renewable energy resources such as solar and wind power but also oil and gas, which are topics of key interest to the Mideast-Mediterranean/North Africa geographic area. Track 3 focuses on computational materials design, especially as applied to energy and infrastructure systems. The goal of the technical program is to leverage regional interests and expertise, particularly along these three tracks.</p> <p>“Materials engineering and research underpins the Qatar Energy and Water Security Grand Challenges,” Dr. Mohammed Khaleel, QEERI executive director said. “The scientific exchange and discussions at the TMS meeting will be very fruitful to researchers here in Qatar working on these two grand challenges. Bringing the TMS congress to Qatar is truly a good example of how well academia, research institutes and industry are working together. In this regard, at QEERI, we value our partnership with Texas A&amp;M at Qatar, Qatar University and QAPCO.”</p> <p>Mariam Ali AlMaadeed, director of the Center for Advanced Materials and coordinator of Materials Science and Technology Master Program at Qatar University, said, “I hope this Materials Conference will bring together researchers and professionals from a broad set of disciplines to discuss the latest developments and solutions in the sustainability, design and functionality of materials. It will provide an excellent opportunity to foster novel materials and technological solutions for a cleaner, cheaper and more efficient energy extraction and storage. MEMA 2015 will catalyze dialogue among the leaders from academia, industry and government to enhance research and to build knowledge based economy as per Qatar National Vision 2030. This conference would be one of the strongest and best ever in terms of the quality of the work being presented as well as the depth and breadth of the technical sessions.”</p> <p>The Minerals, Metals &amp; Materials Society (TMS) is a premier professional organization that encompasses the entire range of materials and engineering, from minerals processing and primary metals production to basic research and the advanced applications of materials. The conference seeks to be the premier forum for presentations of current interest and significance related to sustainable infrastructure materials; materials for energy extraction, conversion and storage; and computational materials design.</p> http://engineering.tamu.edu/news/2015/01/22/texas-am-at-qatar-and-local-partners-host-mema-2015 http://engineering.tamu.edu/news/2015/01/22/texas-am-at-qatar-and-local-partners-host-mema-2015 Thu, 22 Jan 2015 00:00:00 CST Alfriend named 2015 AIAA Honorary Fellow Jan McHarg <> http://engineering.tamu.edu/news/2015/01/21/alfriend-named-2015-aiaa-honorary-fellow <p><img width="210" height="270" src="/media/564049/image-of-terry-alfriend.jpg" alt="Image of Terry Alfriend" class="rightalign"/>The American Institute of Aeronautics and Astronautics (AIAA) has named Dr. Terry Alfriend, professor in the Department of Aerospace Engineering at Texas A&amp;M University, a 2015 AIAA Honorary Fellow.
