Mikaela Spruill
Postdoctoral Scholar, Psychology
BioMikaela Spruill’s research investigates how our judgments and decisions at the individual-level sustain systemic inequities. She works to understand the cognitive processes and social contexts that help facilitate large-scale racial disparities via policy preferences and legal decision-making. She is the Criminal Justice Postdoctoral Fellow with SPARQ at Stanford where she aids in the advancement of the center’s projects on the criminal justice system, with a focus on policing and public safety.

Daniel Stack
Associate Professor of Chemistry
BioResearch in the Stack group focuses on the mechanism of dioxygen activation and the subsequent oxidative reactivity with primarily copper complexes ligated by imidazoles or histamines. Specifically, the group is interested in substrate hydroxylations and full dioxygen reduction. The remarkable specificity and energy efficiency of metalloenzymes provide the inspiration for the work. Trapping and characterizing immediate species, primarily at low temperatures, provide key mechanistic insights especially through substrate reactivity along with spectroscopic and metrical correlation to DFT calculations. Our objective is to move these efficient enzymatic mechanisms into small synthetic complexes, not only to reproduce biological reactivity, but more importantly to move the oxidative mechanism beyond that possible in the protein matrix.
Daniel Stack was born, raised and attended college in Portland Oregon. He received his B.A. from Reed College in 1982 (Phi Beta Kappa), working with Professor Tom Dunne on weak nickel-pyrazine complexes. In Boston, he pursued his doctoral study in synthetic inorganic chemistry at Harvard University (Ph.D., 1988) with Professor R. H. Holm, investigating site-differentiated synthetic analogues of biological Fe4S4 cubanes. As an NSF Postdoctoral Fellow with Professor K. N. Raymond at the University of California at Berkeley, he worked on synthesizing new, higher iron affinity ligands similar to enterobactin, a bacterial iron sequestering agent. He started his independent career in 1991 at Stanford University primarily working on oxidation catalysis and dioxygen activation, and was promoted to an Associate Professor in 1998. His contributions to undergraduate education have been recognized at the University level on several occasions, including the Dinkelspiel Award for Outstanding Contribution to Undergraduate Education in 2003.
Areas of current focus include:
Copper Dioxygen Chemistry
Our current interests focus on stabilizing species formed in the reaction of dioxygen with Cu(I) complexes formed with biologically relevant imidazole or histamine ligation. Many multi-copper enzymes ligated in this manner are capable of impressive hydroxylation reactions, including oxidative depolymerization of cellulose, methane oxidation, and energy-efficient reduction of dioxygen to water. Oxygenation of such complexes at extreme solution temperatures (-125°C) yield transient Cu(III) containing complexes. As Cu(III) is currently uncharacterized in any biological enzyme, developing connections between the synthetic and biological realms is a major focus.
Surface Immobilization of Catalysts in Mesoporous Materials
In redox active biological metal sites, the ligation environment is coupled tightly to the functional chemistry. Yet, the metal sites are also site-isolated, creating species that may only have a transient existence in a homogeneous solution. Site isolation of synthetic complexes can be achieved synthetically by supporting the metal complex on a solid matrix. Movement of these complexes into silica based materials or onto electroactive carbon electrodes represent a new direction for the group in the development of bio-inspired metal-based catalysts. -

Alice Staveley
Senior Lecturer of English
BioAlice Staveley teaches a range of courses on British modernism, contemporary British and Canadian fiction, and Virginia Woolf. She has won the Dean's Award for Distinguished Teaching (2016-2017) and directs the Honors Program in English and the Digital Humanities Minor. She has taught in the Oxford tutorial system, the History and Literature concentration at Harvard University, and Stanford's Introduction to the Humanities Program (2001-2006). Research interests include: modernism; narratology; book and periodical history; women and the professions; feminist and cultural theory; and digital humanities. Her current book project examines Virginia Woolf's life as a publisher. Select publications include: Woolf’s short fictional feminist narratology; Woolf’s European reception; photography in Three Guineas; modernist marketing; and transnational archival feminisms. She co-founded and co-directs of The Modernist Archives Publishing Project, a critical digital archive of documents related to modernist publishing supported by grants from the Social Sciences and Humanities Research Council of Canada, the Arts and Humanities Research Council (UK), and the Roberta Bowman Denning Digital Fund for Humanities and Technologies. http://modernistarchives.com Recent digital humanities research involves quantitative analysis of modernist book-sales records.

Tim Stearns
Professor of Biology
Current Research and Scholarly InterestsWe use the tools of genetics, microscopy, and biochemistry to understand fundamental questions of cell biology: How are cells organized by the cytoskeleton? How do the centrosome and cilium control cell control cell signaling? How is cell division coordinated with duplication of the centrosome, and what goes wrong in cancer cells defective in this coordination?

Claude Steele
Lucie Stern Professor in the Social Sciences, Emeritus
BioClaude M. Steele is an American social psychologist and a Professor of Psychology at Stanford University.
He is best known for his work on stereotype threat and its application to minority student academic performance. His earlier work dealt with research on the self (e.g., self-image, self- affirmation) as well as the role of self-regulation in addictive behaviors. In 2010, he released his book, Whistling Vivaldi and Other Clues to How Stereotypes Affect Us, summarizing years of research on stereotype threat and the underperformance of minority students in higher education.
