After my retirement as director, I was named research fellow and curator of Latin American Collection, of the Hoover Institution of Stanford University in 2011–2017.
My main areas of interests are in comparative social history, quantitative methods in historical research and demographic history. I have published some 25 books dealing with the history of slavery, the Atlantic slave trade, colonial fiscal history, and demographic history and have published extensively on the history of Bolivia, Brazil and the United States. I has been a Woodrow Wilson Fellow, a Guggenheim Fellow, a Fulbright Lecturer in numerous Latin American universities and received grants from the Ford Foundation, the Social Science Research Council, the National Science Foundation, the National Endowment for the Humanities and the Tinker Foundation.
My honors include the 1977 "Socio-Psychological Prize" of the AAAS (American Association for the Advancement of Science), joint with Jonathan Kelley; the 2010 Premio em Historia e Ciencias Sociais of the Academia Brasileira de Letras, for a co-authored book Escravismo em São Paulo e Minas Gerais (joint with Iraci Costa and Francisco Vidal Luna) and in 2015 I received the Distinguished Service Award from the Conference on Latin American History, the professional organization of Latin American historians.

Elias Kleinbock
SLE Lecturer
BioElias Kleinbock is a Lecturer in the Program in Structured Liberal Education (SLE), a first-year residential humanities program at Stanford University.
His research brings modernist cultural production in the German, Soviet, and Anglophone spheres into conversation with the history of the human sciences and the intersecting traditions of Marxism, psychoanalysis, and Spinozism. He received his PhD in Comparative Literature from Princeton University, with a dissertation titled “Labors of Formation: Pedagogy and Collectivity in the Modernist Frame.” His current book project, based on his dissertation, traces out a transindividual, psychosocial conception of teaching and learning in works by 20th-century thinkers including Aleksandr Bogdanov, John Dewey, Bertolt Brecht, and Wilfred R. Bion. Elias's broader interests include poetry and poetics, experimental cinema, pre-Freudian histories of the unconscious, and aesthetic and theoretical treatments of impersonality and theatricality. He is also an amateur theater practitioner, with experience and training in clown, commedia, and Lecoq-style physical theater. -

Nathan Kline
Adolescent Screenomics Study Coordinator, Peds/Disease Prevention
Current Role at StanfordAs the Adolescent Screenomics Study Coordinator, I have collaborated with Dr. Tom Robinson and the rest of the Stanford Solutions Lab team to create the groundwork for the Adolescent Screenomics study. Some of this groundwork includes: developing and maintaining a RedCap project with over 20 instruments and over 800 notifications with branching logic. I also have been collaborating with programmers and RedCap administrators to manage compensation related to smartphone use, create a zoom scheduler to onboard adolescent participants, and automate the distribution of gift cards. Moreover, I have been developing and maintaining our study website. Finally, I have been developing advertisements on Facebook, Instagram, etc. to advertise for our study. Once our study is approved by the IRB officially, I will begin recruiting and onboarding adolescent participants, obtaining informed consent (from their parents/guardians) and assent, and monitoring completion of the study.
