Media Mentions:

Prof. Lance Hoffman (CS) was quoted in the October 17 Washington Post article, " FBI Director Comey calls on Congress to stop unlockable encryption. Good luck with that."

Publications:

Profs. Lawrence Bennett (ECE) and Edward Della Torre (ECE) have published the paper " Bose-Einstein Condensation of Confined Magnons in Nanostructures," in the Journal of Modern Physics, 5, 693-705 2014. The paper is a review of a new field of physics created by Profs. Bennett and Della Torre. The study of atomic Bose-Einstein condensation (BEC) has yielded rich dividends. A promising extension is to magnons—spin-wave quanta that behave as bosonic quasiparticles—in magnetic nanoparticles. This system has unique characteristics differentiating it from atomic BEC, creating the potential for a whole new variety of interesting behaviors and applications that include novel nanomagnetic devices.

On October 17, GW's Cyber Security and Privacy Research Institute (CSPRI) hosted a delegation of German industry and government representatives who met in the dean's conference room in Tompkins Hall with U.S. government officials and researchers to discuss shared cyber security issues and concerns. Present at the meeting were representatives of the U.S. State Department, the National Institutes of Standards and Technology, Rand Corporation, and the Information Technology Industry Council. The discussion topics included the new framework for cyber security promulgated by NIST and the concept of cyber insurance as a policy instrument to address cyber threats. At the end of the discussion, the head of the German delegation, Mr. Arne Schoenbohm, and Prof. Lance Hoffman (CSPRI director) signed an agreement to organize a long term, sustained program of academic exchanges, seminars and collaborative research intended to rebuild the trust between the two nations—traditional actors in a strong partnership in cyber security efforts—that recently has undergone challenges. The point of contact is Prof. Costis Toregas at CSPRI, toregas1@gwu.edu.

Prof. Azim Eskandarian (CEE) served as one of three program chairs of the IEEE Intelligent Transportation Systems Conference 2014, held October 8-11 in Qingdao, China. This conference is the flagship conference of the IEEE ITS Society, and this year's program became the largest and most selective conference in the history of the society. At the conference, Prof. Eskandarian was the chair of the plenary session for the IEEE ITS Society Awards, at which three awards are granted annually to Best Research, Best Application, and Lead Institute, as well as to three students with the best doctoral dissertations (selected by a panel). Prof. Eskandarian also participated as the chair of the society's technical committee for vehicle safety technologies and applications. These activities bring national and international visibility and reputation to GW's transportation safety area.

Graduate Career Services: The GW SEAS Graduate Career Services Team hosted its first live WebEx workshop. The workshop received positive feedback from students, so additional efforts will be made to continue to offer workshops online, as well as in-person. Boeing will host a career day on October 21 in the Jack Morton Auditorium from 3:30 to 6:00 pm. The Boeing team will provide information about internship and full-time opportunities across the country. Space is limited, so students should RSVP on GWork.

Two-dimensional few-layer materials, including the extensively studied graphene and recently rising transition-metal dichalcogenides, offer unique electrical, chemical, and mechanical properties. A more exciting opportunity is to achieve novel optoelectronics and energy harvesting devices by creating heterostructures where individual layers of very different characters are combined, and engineering the strain and defects in these novel materials.

Prof. Tianshu Li has been taking the initiative to explore the opportunities for creating novel heterostructured 2D few-layer materials. Toward this goal, he is currently focused on gaining a fundamental understanding of the nature of the 2D materials, by investigating their intrinsic properties and the interactions arising when multiple layers are combined. Employing an advanced computational approach, Prof. Li has predicted the variation of the electronic and mechanical properties of monolayer MoS2 upon strain. Very recently, his research team also discovered the origin of the interlayer electronic coupling when two monolayer MoS2 layers are arbitrarily stacked to form 2D bilayers. This finding provides the theoretical explanation to the photoluminescence spectroscopy measured in twisted MoS2 bilayers.

The Cyber Security Policy and Research Institute in the School of Engineering and Applied Science, has joined a cooperative effort with the School of Media and Public Affairs in the Columbian College of Arts and Sciences, the Institute for International Economic Policy in the Elliot School of International Affairs, and the Law School to present this seminar series. Running themes include the tensions between freedom and (cyber)security, privacy and publicity, and commercial development and the public good. The series events frame the underlying issues and address competing prescriptive measures, such as industry self-regulation and transparency reporting, as well as the technological implications and constraints. More details on all the four roundtable events this academic year and background material for the first meeting (on the topic of Net Neutrality) are available at go.gwu.edu/gwifg .
