CS Colloquium: William Regli (DARPA) - Defense Sciences Office 101
Tue, Jun 09, 2015 @ 10:30 AM - 11:30 AM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: William Regli , DARPA
Talk Title: Defense Sciences Office 101
Series: CS Colloquium
Abstract: The Defense Advanced Research Projects Agency (DARPA) was established in 1958 to prevent strategic surprise from negatively impacting U.S. national security and create strategic surprise for U.S. adversaries by maintaining the technological superiority of the U.S. military. To fulfill its mission, the Agency relies on diverse performers to apply multi-disciplinary approaches to both advance knowledge through basic research and create innovative technologies that address current practical problems through applied research. As the DoD's primary innovation engine, DARPA undertakes projects that are finite in duration but that create lasting revolutionary change.
The Defense Sciences Office (DSO) is one of six technical offices at the agency. DSO identifies and pursues high-risk, high-payoff fundamental research initiatives across a broad spectrum of science and engineering disciplines including materials science, computing and autonomy, engineering design and manufacturing, physics, chemistry and pure and applied mathematics.
This presentation will give an overview of DARPA, working with DARPA and the Defense Sciences Office, and description of some of the current activities DSO's program managers are working on.
Biography: Dr. William Regli joined DARPA as the Deputy Director of the Defense Sciences Office in September 2014. Dr. Regli is a computer scientist with a passion for addressing interdisciplinary and use-inspired problems using knowledge representation, physics-based modeling and other computational techniques. Dr. Regli has published more than 250 technical articles, including those in leading venues for research in computer graphics, artificial intelligence, robotics, wireless networking, tissue engineering, and engineering design and manufacturing. His research has spawned two start-up technology companies (one focused on mobile communications for public safety, the other on information management in edge networks) and resulted in five U.S. Patents. Dr. Regli's most recent activities have focused on deploying cyber-infrastructure systems to capture and curate engineering and science data, and ensure the long-term sustainability of data. His current interests include computational tools to exploit the properties of advanced materials, additive manufacturing systems and enabling new paradigms for design and production.
Dr. Regli holds a Doctor of Philosophy degree in Computer Science from the University of Maryland at College Park and Bachelor of Science degree in Mathematics from Saint Joseph's University. He has been on the faculty of Drexel University since 1997, most recently as Professor of Computer and Information Science and Senior Associate Dean for Research and Scholarly Activities for the Drexel College of Computing and Informatics. Dr. Regli's federal service includes a National Research Council Postdoctoral Fellowship at the National Institute of Standards and Technology (NIST) and an ongoing role as Scientific Adviser to the Defense Programs Office of the U.S. Department of Energy's (DoE) National Nuclear Security Administration (NNSA) in the areas of information technology and advanced manufacturing.
He is an elected senior member of the Association of Computing Machinery (ACM), the Institute of Electrical and Electronics Engineers (IEEE) and the Association for the Advancement of Artificial Intelligence (AAAI).

Fluid-Structure Interactions: From Flow-Induced Vibrations to Bio-Inspired Propulsion
Tue, Jun 09, 2015 @ 02:00 PM - 03:00 PM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Francisco Huera-Huarte, Visiting Associate in Aerospace at Caltech; Department of Mechanical Engineering Universitat Rovira i Virgili (URV), Tarragona, Spain
Talk Title: Fluid-Structure Interactions: From Flow-Induced Vibrations to Bio-Inspired Propulsion
Abstract: Francisco Huera-Huarte will be showing some examples of very recent work carried out in his lab, related to glow-induced vibration and bio-inspired propulsion.
Since the 70's there has been an increased interest in the dynamics of offshore structures because of the recent highly demanding industrial applications such as those found in offshore wind energy or in oil exploration and extraction. Part of Huera-Huarte's work deals with the description of the structural and fluid dynamics of highly flexible structures when affected by currents. These flexible structures vibrate at different structural modes as a consequence of very complex fluid-structure interaction phenomena. He will be showing recent experimental work carried out in order to describe the near wake of one of these structures when affected by a current.
The other topic Huera-Huarte will consider is related to bio-inspired propulsion systems. Aquatic locomotion in fish is characterized by complex kinematics, governed not only by passive bony or cartilaginous structures, but also by active ones and tissue such as muscles. There has been a wide interest in the recent years regarding the understanding of the role of stiffness in flapping propulsion because of the implications of this topic, especially in all related to the design of underwater robotic systems. It is now evident that compliance and shape play an important role in propulsion. He will show some results obtained with flexible robotic fins (foils), and discuss the role of flexibility, the effect of the proximity of a wall in the swimming performance of a flexible foil, and ongoing work related to active control of fins to improve their overall thrust.
