On Monday, April 16, a panel discussion, colloquium, and lecture make up this year's three-part CRA-W Distinguished Lecture Series. Sponsored by the Committee on the Status of Women in Computing Research (CRA-W), UMBC’s Center for Women in Technology (CWIT), UMBC’s Computer Science and Electrical Engineering (CSEE) Department, UMBC’s Information Systems (IS) Department, the Graduate School at UMBC, and WISE and ADVANCE at UMBC,  the lecture series approaches topics ranging from how to succeed in graduate school to computing challenges.

10:00 A.M., Room 310, University Center

The Panel Discussion, entitled "Graduate School: Before, During, and After" features a panel of UMBC graduate students and academic professionals who will talk about common issues facing prospective graduate students. Questions like "Should I go to graduate school?" "Should I choose an M.S. or Ph.D.?" and "What jobs will be open to me after graduate school?" will be tackled.

Dr. Ellen Zegura, Professor and Chair of the School of Computer Science at Georgia Tech and Dr. Jeffrey Forbes, a Duke University professor of Computer Science currently on leave with the National Science Foundation as a Program Director for the Education and Workforce Program in the Division of Computer and Network Systems, Directorate for Computer and Information Science and Engineering, will be part of the panel. Mr. James MacGlashan, a Ph.D. candidate within the CSEE Department and Ms. Alyson Young, a Human-Centered Computing (HCC) Ph.D. Student will join them for the discussion.

1:00 – 2:00 P.M., Information Technology/Engineering (ITE) Building 325B

The Computer Science and Information Systems Joint Colloquium will feature a talk by Dr. Ellen Zegura entitled "Computing in Cirrus Clouds: The Challenge of Intermittent Connectivity."

Abstract
Mobile devices are increasingly relied on for services that go beyond simple connectivity and require more complex processing. Improved connectivity options for mobile devices have enabled applications that transcend an individual device's capabilities by making use of remote processing and storage.

The primary approach in wide use today to enable such remote processing makes use of cloud computing resources to offload the "heavy lifting" that may be required in some mobile applications to specially designated servers or server clusters. In reality, a mobile device often encounters, albeit intermittently, many entities capable of lending computational resources. We call these alternative settings "cirrus clouds". In this talk I will discuss the unique challenges posed by intermittent connectivity and describe some early progress on managing such a setting.

4:00 – 5:00 P.M., Albin O. Kuhn Library Gallery

The CRA-W Distinguished Lecture will feature a talk by Dr. Ellen Zegura entitled "Computing for Good: Experiences in Humanitarian Computing."

Abstract
Almost four years ago, I was involved in the creation of Computing for Good (C4G), a Georgia Tech College of Computing initiative centered around using computing to help solve pressing societal problems. The primary activity of C4G has been a project-based course taught once per year and taken by seniors (satisfying the capstone requirement) and masters-level graduate students.  Projects with life beyond one semester are frequently taken up by master's students as MS projects.

Over the last year, I have had the opportunity to work closely with the Carter Center and their Mental Health Program in Liberia. With students in the C4G fall 2010 course, my experiences have included technology consulting, technology training, technology integration, and technology invention. I have also had the chance to observe first hand a set of additional country-wide challenges where computing might play a role.  In this talk, I will describe my experiences and highlight additional opportunities for computationalists.

Cyber-Physical Social Systems: Research Challenges

We are witnessing a new revolution in computing and communication. The Internet, which has spanned several networks in a wide variety of domains, is having a significant impact on every aspect of our lives. The next generation of networks will utilize a wide variety of resources with significant sensing capabilities. Such networks will extend beyond physically linked computers to include multimodal information from biological, cognitive, semantic, and social networks. This paradigm shift will involve symbiotic networks of people (social networks), intelligent devices, and mobile personal computing and communication devices (mPCDs), that will form net-centric societies (NCS) or cyber-physical social systems (CPSS). mPCDs are already equipped with myriad sensors, with regular updates of additional sensing capabilities. Additionally, we are witnessing the emergence of “intelligent devices,” such as smart meters, smart cars, etc., with considerable sensing and networking capabilities. Hence, these devices – and the network — will be constantly sensing, monitoring, and interpreting the environment; this is sometimes referred to as the Internet of Things (IOT). The symbiosis of IOT and social networks will have significant implications for both the market for advanced computing and communication infrastructure and the future markets – for nearly 4.5 billion people — that CPSS will create. In this seminar, I will provide an overview of the Software and Systems Division at NIST, followed by a discussion of research challenges for CPSS with a specific focus on smart healthcare.

Dr. Ram D. Sriram is currently the chief of the Software and Systems Division, Information Technology Laboratory, at the National Institute of Standards and Technology. Before joining the Software and Systems Division, Sriram was the leader of the Design and Process group in the Manufacturing Systems Integration Division, Manufacturing Engineering Laboratory, where he conducted research on standards for interoperability of computer-aided design systems. He was also the manager of the Sustainable Manufacturing Program. Prior to joining NIST, he was on the engineering faculty (1986-1994) at the Massachusetts Institute of Technology (MIT) and was instrumental in setting up the Intelligent Engineering Systems Laboratory. Sriram has co-authored or authored nearly 250 publications, including several books. Sriram was a founding co-editor of the International Journal for AI in Engineering. In 1989, he was awarded a Presidential Young Investigator Award from the National Science Foundation. In 2011, Sriram received the ASME Design Automation Award for his work on computer-supported collaborative design. Sriram is a Fellow of ASME and AAAS, a member (life) of ACM, a Senior Member of the IEEE, and a member (life) of AAAI. Sriram has a B.Tech. from IIT, Madras, India, and an M.S. and a Ph.D. from Carnegie Mellon University, Pittsburgh, USA.

Neurons grow and develop in the three-dimensional (3D) environment of the developing embryo. Previous work from our group has demonstrated that culturing embryonic neurons in 3D matrices allows the cells to respond in a way that more closely resembles natural development than traditional two-dimensional (2D) culture. Cells interact with their extracellular matrix and sense the dimensionality of their surroundings via integrin receptors on the cell surface that bind to matrix molecules, initiate intracellular signaling cascades and affect changes in cell shape and function. Our work focuses on elucidating the signaling events that regulate these changes in cell response. We hypothesize that 3D environments impose changes in matrix-ligand organization and alter neuronal behavior by modulating β1-integrin cytoskeleton signaling. PC12 cells, a neuronal cell model, were cultured on 2D and within 3D collagen substrates and probe the signaling response by inhibiting several key signaling molecules involved in regulating neuron morphology: β1-integrin, Focal Adhesion Kinase (FAK), and an activated form of FAK that is phosphorylated at tyrosine 397. The results of this study will identify the key signaling mechanisms in 3D neuronal culture and provide a biological basis for testing new biomaterial-based therapeutics.
