Grant M. Rotskoff
Assistant Professor of Chemistry
BioGrant Rotskoff studies the nonequilibrium dynamics of living matter with a particular focus on self-organization from the molecular to the cellular scale. His work involves developing theoretical and computational tools that can probe and predict the properties of physical systems driven away from equilibrium. Recently, he has focused on characterizing and designing physically accurate machine learning techniques for biophysical modeling. Prior to his current position, Grant was a James S. McDonnell Fellow working at the Courant Institute of Mathematical Sciences at New York University. He completed his Ph.D. at the University of California, Berkeley in the Biophysics graduate group supported by an NSF Graduate Research Fellowship. His thesis, which was advised by Phillip Geissler and Gavin Crooks, developed theoretical tools for understanding nonequilibrium control of the small, fluctuating systems, such as those encountered in molecular biophysics. He also worked on coarsegrained models of the hydrophobic effect and self-assembly. Grant received an S.B. in Mathematics from the University of Chicago, where he became interested in biophysics as an undergraduate while working on free energy methods for large-scale molecular dynamics simulations.
Research Summary
My research focuses on theoretical and computational approaches to "mesoscale" biophysics. Many of the cellular phenomena that we consider the hallmarks of living systems occur at the scale of hundreds or thousands of proteins. Processes like the self-assembly of organelle-sized structures, the dynamics of cell division, and the transduction of signals from the environment to the machinery of the cell are not macroscopic phenomena—they are the result of a fluctuating, nonequilibrium dynamics. Experimentally probing mesoscale systems remains extremely difficult, though it is continuing to benefit from advances in cryo-electron microscopy and super-resolution imaging, among many other techniques. Predictive and explanatory models that resolve the essential physics at these intermediate scales have the power to both aid and enrich the understanding we are presently deriving from these experimental developments.
Major parts of my research include:
1. Dynamics of mesoscale biophysical assembly and response.— Biophysical processes involve chemical gradients and time-dependent external signals. These inherently nonequilibrium stimuli drive supermolecular organization within the cell. We develop models of active assembly processes and protein-membrane interactions as a foundation for the broad goal of characterizing the properties of nonequilibrium biomaterials.
2. Machine learning and dimensionality reduction for physical models.— Machine learning techniques are rapidly becoming a central statistical tool in all domains of scientific research. We apply machine learning techniques to sampling problems that arise in computational chemistry and develop approaches for systematically coarse-graining physical models. Recently, we have also been exploring reinforcement learning in the context of nonequilibrium control problems.
3. Methods for nonequilibrium simulation, optimization, and control.— We lack well-established theoretical frameworks for describing nonequilibrium states, even seemingly simple situations in which there are chemical or thermal gradients. Additionally, there are limited tools for predicting the response of nonequilibrium systems to external perturbations, even when the perturbations are small. Both of these problems pose key technical challenges for a theory of active biomaterials. We work on optimal control, nonequilibrium statistical mechanics, and simulation methodology, with a particular interest in developing techniques for importance sampling configurations from nonequilibrium ensembles. -

Nancy Ruttenburg
William Robertson Coe Professor of American Literature, Emerita
BioNancy Ruttenburg is the William Robertson Coe Professor of American Literature in the English Department at Stanford. She also holds courtesy appointments in the Department of Comparative Literature and the Department of Slavic Languages and Literatures. She received the PhD in Comparative Literature from Stanford (1988) and taught at Harvard, Berkeley, and most recently at NYU, where she was chair of the Department of Comparative Literature from 2002-2008. Her research interests lie at the intersection of political, religious, and literary expression in colonial through antebellum America and nineteenth-century Russia, with a particular focus on the development of liberal and non-liberal forms of democratic subjectivity. Related interests include history of the novel, novel theory, and the global novel; philosophy of religion and ethics; and problems of comparative method, especially as they pertain to North American literature and history.
Prof. Ruttenburg is the author of Democratic Personality: Popular Voice and the Trial of American Authorship (Stanford UP, 1998) and Dostoevsky's Democracy (Princeton UP, 2008), and she has recently written on the work of J. M. Coetzee and on Melville’s “Bartleby.” Books in progress include a study of secularization in the postrevolutionary United States arising out of the naturalization of “conscience” as inalienable right, entitled Conscience, Rights, and 'The Delirium of Democracy'; and a comparative work entitled Dostoevsky And for which the Russian writer serves as a lens on the historical development of a set of intercalated themes in the literature of American modernity. These encompass self-making and self-loss (beginning with Frederick Douglass's serial autobiographies); sentimentalism and sadism (in abolitionist fiction); crime and masculinity (including Mailer's The Executioner's Song); and the intersection of race, religious fundamentalism, and radical politics (focusing on the works of James Baldwin and Marilynne Robinson). Her courses will draw from both these projects.
Prof. Ruttenburg is past president of the Charles Brockden Brown Society and has been the recipient of a Guggenheim Fellowship, a National Humanities Center Fellowship, a University of California President's Research Fellowship, as well as fellowships from the Social Science Research Council for Russian and East European Studies, the National Endowment for the Humanities, and the American Council for Learned Societies. -

Ramon Saldivar
Hoagland Family Professor of Humanities and Sciences and Professor of English, of Comparative Literature and, by courtesy, of Iberian and Latin American Cultures
Current Research and Scholarly InterestsMy current research is concerned with the relationships among race, form, genre, representing what Jeffrey T. Nealon has recently term the “post-postmodern.” In the latest version of this research presented at the John-F.-Kennedy-Institut für Nordamerikastudien, Freie Universität Berlin I use Sesshu Foster's "Atomik Aztex" as an example twenty-first century racial imaginaries. Part fantasy, part hallucinatory sur-realism, part muckraking novel in the grand realist protest tradition of Upton Sinclair’s The Jungle (1906), part historical novel in the mode of Vassily Grossman’s great Stalinist era masterpiece, Life & Fate (1980) set during the battle of Stalingrad, part ethnographic history about religious, military, and social structure of the pre-Columbian Aztec (Nahua, Mexica) world, part LA noir, and wholly Science Fiction alternative and counterfactual history, it exemplifies many of the criteria of the “post-postmodern.” Moreover, in addition to this range of formal matters, Atomik Aztex is concerned with two other topics:
•a reconceptualization of the way that race affects the formations of history, and
•the reshaping of the form of the novel in order to represent that reconceptualization.
With eighty-two characters populating the story, itself a plotted compendium of at least two radically separate yet intertwined universes of action, in a continually shifting movement from past, present, and future times, Atomik Aztex is a radical experiment in novelistic form. Using the tools of quantitative formalism developed for literary use by the Stanford University Literary Lab, I wish to show how the work of the computational humanities, in conjunction with traditional hermeneutic methods of literary analysis can help us understand the radical turn of contemporary American fiction toward speculative realism. -
