Tomás R. Jiménez
Professor of Sociology
BioTomás Jiménez is a Professor of Sociology and Comparative Studies in Race and Ethnicity and the founding co-director of Stanford's Institute for Advancing Just Societies. His research and writing focus on immigration, policy, assimilation, social mobility, and ethnic and racial identity. His latest book, States of Belonging: Immigration Policies, Attitudes, and Inclusion (Russell Sage Foundation Press) (with Deborah Schildkraut, Yuen Ho, and John Dovidio) uses survey data (with an embedded experiment) and in-depth interviews to understand how state-level immigration policies shape belonging among Latino immigrants, US-born Latinos, and US-born whites in Arizona and New Mexico. The American Sociological Association’s Population Section selected the book for its Otis Dudley Duncan Distinguished Book Award. His second book, The Other Side of Assimilation: How Immigrants are Changing American Life (University of California Press, 2017), uses interviews from a race and class spectrum of Silicon Valley residents to show how a relational form of assimilation changes both newcomers (immigrants and their children) and established individuals (people born in the US to US-born parents). His first book, Replenished Ethnicity: Mexican Americans, Immigration, and Identity(University of California Press, 2010), draws on interviews and participant observation to understand how uninterrupted Mexican immigration influences the ethnic identity of later-generation Mexican Americans. Professor Jiménez has also published his research in Science, American Sociological Review, American Journal of Sociology, American Political Science Review, Proceedings of the National Academy of Sciences, Social Problems, International Migration Review, Ethnic and Racial Studies, Social Science Quarterly, DuBois Review, Social Currents, Qualitative Sociology, and the Annual Review of Sociology.
Professor Jiménez also conducts research with Stanford's Immigration Policy Lab, including projects examining naturalization, refugee resettlement, and health and language access.
In other lines of research, Professor Jiménez and Sofia Avila (Princeton sociology) examine how immigration becomes part of American national identity by studying a sample of high school US history textbooks from 1930-2007. This research employs hand-coding and computer-assisted text analysis of the textbook sample.
Professor Jiménez has taught at the University of California, San Diego. He was the Sigma Xi Distinguished Lecturer (2017-19). He has also been an Irvine Fellow at the New America Foundation and a Sage Fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford University (CASBS).

Matthew Kanan
Professor of Chemistry
BioAssociate Professor of Chemistry Matthew Kanan develops new catalysts and chemical reactions for applications in renewable energy conversion and CO2 utilization. His group at Stanford University has recently developed a novel method to create plastic from carbon dioxide and inedible plant material rather than petroleum products, and pioneered the study of “defect-rich” heterogeneous electro-catalysts for converting carbon dioxide and carbon monoxide to liquid fuel.
Matthew Kanan completed undergraduate study in chemistry at Rice University (B.A. 2000 Summa Cum Laude, Phi Beta Kappa). During doctoral research in organic chemistry at Harvard University (Ph.D. 2005), he developed a novel method for using DNA to discover new chemical reactions. He then moved into inorganic chemistry for his postdoctoral studies as a National Institutes of Health Postdoctoral Research Fellow at the Massachusetts Institute of Technology, where he discovered a water oxidation catalyst that operates in neutral water. He joined the Stanford Chemistry Department faculty in 2009 to continue research into energy-related catalysis and reactions. His research and teaching have already been recognized in selection as one of Chemistry & Engineering News’ first annual Talented 12, the Camille Dreyfus Teacher-Scholar Award, Eli Lilly New Faculty Award, and recognition as a Camille and Henry Dreyfus Environmental Mentor, among other honors.
The Kanan Lab addresses fundamental challenges in catalysis and synthesis with an emphasis on enabling new technologies for scalable CO2 utilization. The interdisciplinary effort spans organic synthesis, materials chemistry and electrochemistry.
One of the greatest challenges of the 21st century is to transition to an energy economy with ultra-low greenhouse gas emissions without compromising quality of life for a growing population. The Kanan Lab aims to help enable this transition by developing catalysts and chemical reactions that recycle CO2 into fuels and commodity chemicals using renewable energy sources. To be implemented on a substantial scale, these methods must ultimately be competitive with fossil fuels and petrochemicals. With this requirement in mind, the group focuses on the fundamental chemical challenge of making carbon–carbon (C–C) bonds because multi-carbon compounds have higher energy density, greater value, and more diverse applications that one-carbon compounds. Both electrochemical and chemical methods are being pursued. For electrochemical conversion, the group studies how defects known as grain boundaries can be exploited to improve CO2/CO electro-reduction catalysis. Recent work has unveiled quantitative correlations between grain boundaries and catalytic activity, establishing a new design principle for electrocatalysis, and developed grain boundary-rich copper catalysts with unparalleled activity for converting carbon monoxide to liquid fuel. For chemical CO2 conversion, the group is developing C–H carboxylation and CO2 hydrogenation reactions that are promoted by simple carbonate salts. These reactions provide a way to make C–C bonds between un-activated substrates and CO2 without resorting to energy-intensive and hazardous reagents. Among numerous applications, carbonate-promoted carboxylation enables the synthesis of a monomer used to make polyester plastic from CO2 and a feedstock derived from agricultural waste.
In addition to CO2 chemistry, the Kanan group is pursuing new strategies to control selectivity in molecular catalysis for fine chemical synthesis. Of particular interest in the use of electrostatic interactions to discriminate between competing reaction pathways based on their charge distributions. This effort uses ion pairing or interfaces to control the local electrostatic environment in which a reaction takes place. The group has recently shown that local electric fields can control regioselectivity in isomerization reactions catalyzed by gold complexes. -

Reinhard Family Professor, Professor (Research) of Ophthalmology and, by courtesy, of Medicine (Cardiovascular Medicine)
Current Research and Scholarly InterestsDr. Michael S. Kapiloff is a faculty member in the Departments of Ophthalmology and Medicine (Cardiovascular Medicine) and a member of the Stanford Cardiovascular Institute. Although Dr. Kapiloff was at one time a Board-Certified General Pediatrician, he is currently involved in full-time basic science and translational research. His laboratory studies the basic molecular mechanisms underlying the response of the retinal ganglion cell and cardiac myocyte to disease. The longstanding interest of his laboratory is the role in intracellular signal transduction of multimolecular complexes organized by scaffold proteins. Recently, his lab has also been involved in the translation of these concepts into new therapies, including the development of new AAV gene therapy biologics for the prevention and treatment of heart failure and for neuroprotection in the eye.
