How Do our Lives Translate to Data?
Interdisciplinary Artist, Professor
After 9/11, Bangladeshi-born American interdisciplinary artist Hasan Elahi was the subject of an intensive, erroneous FBI investigation. He responded by putting his entire life online, from his financial data to transportation logs. The resulting project, "Tracking Transcience," explores the relationship between location, repetition, technology, and surveillance in the media age.
Hasan Elahi is an interdisciplinary artist working with issues in surveillance, privacy, migration, citizenship, technology, and the challenges of borders. Elahi has spoken at Tate Modern, the American Association of Artificial Intelligence, International Association of Privacy Professionals, TED Global, and the World Economic Forum.
Elahi is currently an associate professor of art at the University of Maryland, and from 2011 to 2014 was the Director of the Design | Cultures + Creativity in the Honors College.

High entropy alloys and how to strengthen them
Presented by: Tai-Gang Nieh
In this presentation, I will first give a brief overview of the recent development of high-entropy alloys and, then, discuss and summarize different traditional strengthening mechanisms that have been observed in high-entropy alloys. Some of these mechanisms are useful for low-temperature and some for high-temperature applications. Special emphasis is placed on the perspective of developing precipitation-hardened alloys for both low and high temperature applications. Examples of coherent precipitates strengthened fcc-base alloys, such as Al and Ti-modified NiFeCoCr, will be given. Microstructure-wise, these precipitation-hardened alloys, in fact, bear great resemblance to the well-known γ-γ' Ni-base superalloys. Aging response as well as strengthening of this alloy will be presented. Finally, if time permits, I will discuss the intrinsic strength (or frictional stress) resulting from lattice distortion induced by the uniform distribution of concentrated constituent elements. The measurements of intrinsic strength will correct the misuse of traditional solid-solution theory for the
explanation of the apparent high strength in high-entropy alloys.
Biography: Dr. T.G. Nieh is currently a professor in Department of Materials Science and Engineering at The University of Tennessee. From 1980 to 1992, he worked at Lockheed Missiles and Space Co. (now Lockheed-Martin Corporation) as a Senior Fellow of Research Laboratory. He subsequently worked at Lawrence Livermore National Laboratory as a Senior Research Fellow until he joined UT in 2004. Nieh is a world leader in superplasticity and superplastic forming. He is also widely recognized for his work in several material science disciplines, including multicomponent complex alloys (including high entropy alloys and bulk metallic glasses), nanocrystalline materials, lightweight alloys, metal-matrix composites, intermetallics, refractory metals and nanolaminates. He published over 400 papers and a textbook on “Superplasticity of metals and ceramics'. He is now serving as Editor-in-Chief, Journal of Intermetallics., has served as Editor, Materials Letters, 2008-2013. Nieh received the Ph.D. degree in Materials Science and Engineering from Stanford University, the M.S. degree in Physics from University of Washington, Seattle, and the B.S. degree in Physics from National Cheng-Kung University in Taiwan.

"Self-assembly of new structures and materials with DNA-coated colloids"
Presented by David Pine
Abstract: Coating colloidal particles and clusters with DNA, we program interactions between colloids, using their shape to make crystal structures that have previously been difficult or even impossible to make. Some of the structures have no known atomic equivalent. Use of different materials allows the structures to be modified after being assembled leading to new open structures with interesting optical and mechanical properties.
Biography: David Pine is Silver Professor of Physics and Chair of the Department of Chemical & Biomolecular Engineering at New York University. His research interests focus broadly on self-assembly of mesoscale materials, with particular interests in colloids, emulsions, and polymers. Recent projects include the development of patchy colloids, DNA-coated colloids, lock-and-key colloids, light-activated colloidal swimmers, and random organization of driven particle suspensions far from equilibrium. He is also interested in the optical properties of soft materials, and was one of the original developers of diffusing-wave spectroscopy, a light scattering technique for probing the dynamics of optically dense multiply-scattering materials. He has taught at Haverford College, worked at Exxon Corporate Research, and held faculty positions at UCSB in chemical engineering and materials and at New York University in physics. He also holds an appointment as Fellow Professor of Polymer Science & Engineering at Sungkyunkwan University in South Korea.
