Martin Jander
Overseas Studies - Berlin, Bing Overseas Studies
BioDr. Jander was born in Freiburg im Breisgau. During his studies of German, History, Sociology, and Political Science in the late 1970s and early 1980s in West-Berlin, he established contact with several opposition members in the GDR and followed their activities. Since then, the topic of opposition in the GDR has been one of his main research fields. Martin Jander's second important field of research is German left-wing terrorism and its international connections. In both fields of research, Jander is particularly interested in references to Antisemitism. Together with Anetta Kahane, he developed the concept of an "unfinished republic" to describe the current Federal Republic of Germany (M. Jander, A. Kahane: Gefährdungen demokratischer Kultur: Die unvollendete Republik, 2020). The republic refuses to understand itself to the full extent as an immigration society. It also refuses to see itself to the full extent as a successor society to National Socialism.

Jlateh Vincent Jappah
Ph.D. Student in Health Policy, admitted Autumn 2021
Master of Arts Student in Economics, admitted Spring 2024BioJlateh Vincent Jappah is a PhD Candidate in Health Policy (Health Economics) at Stanford. His research interests intersect between methods that enhance access to the social determinants of health and the provision of appropriate and timely healthcare services, with the aim of reducing avoidable morbidity and mortality and improving overall health and well-being, especially for underserved and vulnerable populations.
Jappah contends that although health insurance and access to healthcare services are important elements in the health production function, other structural and socio-economic factors collude to either foster or erode health. As such, he has a keen interest in public policy, economics, medicine, global public health, maternal and child health, and a curiosity to understand those socio-political and institutional forces that shape health and well-being. He is also interested in machine learning and artificial intelligence in healthcare.
In addition to the United States, Jappah has lived and worked in several countries in Africa, Asia, and Europe.
He is bi-lingual (English and Russian). -

Thomas Jaramillo
Professor of Chemical Engineering, of Energy Science Engineering, of Photon Science and Senior Fellow at the Precourt Institute for Energy
BioRecent years have seen unprecedented motivation for the emergence of new energy technologies. Global dependence on fossil fuels, however, will persist until alternate technologies can compete economically. We must develop means to produce energy (or energy carriers) from renewable sources and then convert them to work as efficiently and cleanly as possible. Catalysis is energy conversion, and the Jaramillo laboratory focuses on fundamental catalytic processes occurring on solid-state surfaces in both the production and consumption of energy. Chemical-to-electrical and electrical-to-chemical energy conversion are at the core of the research. Nanoparticles, metals, alloys, sulfides, nitrides, carbides, phosphides, oxides, and biomimetic organo-metallic complexes comprise the toolkit of materials that can help change the energy landscape. Tailoring catalyst surfaces to fit the chemistry is our primary challenge.

Daniel Jarosz
Senior Associate Dean, Basic Science, Professor of Chemical and Systems Biology and of Developmental Biology
Current Research and Scholarly InterestsMy laboratory studies conformational switches in evolution, disease, and development. We focus on how molecular chaperones, proteins that help other biomolecules to fold, affect the phenotypic output of genetic variation. To do so we combine classical biochemistry and genetics with systems-level approaches. Ultimately we seek to understand how homeostatic mechanisms influence the acquisition of biological novelty and identify means of manipulating them for therapeutic and biosynthetic benefit.

Hakeem Jefferson
Assistant Professor of Political Science
BioI am an assistant professor of political science at Stanford University where I am also a faculty affiliate with the Center for Comparative Studies in Race and Ethnicity and the Stanford Center for American Democracy. I received my PhD in political science from the University of Michigan and a Bachelor of Arts degree in political science and African American Studies from the University of South Carolina.
My research focuses primarily on the role identity plays in structuring political attitudes and behaviors in the U.S. I am especially interested in understanding how stigma shapes the politics of Black Americans, particularly as it relates to group members’ support for racialized punitive social policies. In other research projects, I examine the psychological and social roots of the racial divide in Americans’ reactions to officer-involved shootings and work to evaluate the meaningfulness of key political concepts, like ideological identification, among Black Americans.
My dissertation, "Policing Norms: Punishment and the Politics of Respectability Among Black Americans," was a co-winner of the 2020 Best Dissertation Award from the Political Psychology Section of the American Political Science Association. -
