cas : fellows 2006-2007 CAS Fellows are untenured UIUC faculty members whose proposals are selected in an annual competition. These appointments grant one semester of teaching release time in order to pursue an individual scholarly or creative project. With the Professors and Associates, they form the core of the Center for Advanced Study Community. Fellows also participate in a yearly roundtable discussion of research interests and are invited to offer a future CAS presentation. **Brian DeMarco physics QUANTUM SIMULATION USING ULTRA-COLD ATOMS My research program concentrates on working toward resolving outstanding questions regarding many-body quantum mechanics by realizing quantum simulation using ultra-cold atoms trapped in an optical lattice. We will complete and test the experimental tools required for this research, and explore the technical limitations of various methods for quantum simulation in this system. bdemarco@uiuc.edu **Minh Do electrical & computer engineering SAMPLING SIGNALS FROM A UNION OF SUBSPACES Sampling is a corner stone of signal processing that allows real-life signals in the continuous domain to be represented and processed in the discrete-domain by computers via measured samples. This research aims to fundamentally extend the existing sampling theory by considering signals from a union of subspaces instead of a single vector space. minhdo@uiuc.edu **Clarence Lang african-american studies & research and history BLACK WORKING-CLASS FORMATION AND SOCIAL MOVEMENTS IN ST. LOUIS, MISSOURI, 1936-1969 Using the border-state city of St. Louis, Missouri as an illustration, this project argues that the historical development of African American urban working-class communities propelled the major black social movements that occurred between 1936 and 1969, including the modern Civil Rights Struggle. The black popular agendas emerging from these movements represented the racial and class interests of African American working people, not only in demands for political participation, but also for social citizenship—greater employment opportunity, and better housing, education and public services. celang@uiuc.edu Lisa Rosenthal art history FOR PLEASURE, PROFIT, AND PERSUASION: CONSTRUCTIONS OF ART'S MANY VIRTUES IN THE NETHERLANDS OF THE SEVENTEENTH CENTURY This project is a book-length study of the theme of artistic virtue in seventeenth-century Dutch and Flemish paintings and prints. It specifically explores how constructions of art’s pleasures, profitability, and persuasive powers served three contested domains of cultural meaning: the body, the home, and the political sphere. lrosenthal@uiuc.edu **Christian Sandvig speech communication VISUALIZATIONS OF THE ELECTROMAGNETIC SPECTRUM IN POLICY DEBATES ABOUT WIRELESS Recent advances in communication regulation and in wireless technology have made measurement of the electromagnetic spectrum newly relevant in policy debates. This research investigates the tactics, aesthetics, and consequences of visualizing these measurements, and considers the way that new cartographies of electromagnetic radiation affect the ability to imagine communication systems, technology, and nature. csandvig@uiuc.edu **M. Christina White chemistry HYDROCARBON FUNCTIONALIZATION METHODS FOR SYNTHESIS We propose to discover and develop a general "toolbox" of selective methods for C-H functionalization for the synthesis of complex molecules. Such methods will impact significantly on the discovery of small molecules for human health. mcwhite@uiuc.edu **These faculty members have been recommended for appointment as Beckman Fellows in the Center for Advanced Study named for the donor of a gift that permits additional recognition for outstanding younger Fellow candidates who have already made distinctive scholarly contributions.
