The J.G. Jackson and C.J. Wood Professor of Chemistry
BioProfessor Dai’s research spans chemistry, physics, and materials and biomedical sciences, leading to materials with properties useful in electronics, energy storage and biomedicine. Recent developments include near-infrared-II fluorescence imaging, ultra-sensitive diagnostic assays, a fast-charging aluminum battery and inexpensive electrocatalysts that split water into oxygen and hydrogen fuels.
Born in 1966 in Shaoyang, China, Hongjie Dai began his formal studies in physics at Tsinghua U. (B.S. 1989) and applied sciences at Columbia U. (M.S. 1991). He obtained his Ph.D. from Harvard U and performed postdoctoral research with Dr. Richard Smalley. He joined the Stanford faculty in 1997, and in 2007 was named Jackson–Wood Professor of Chemistry. Among many awards, he has been recognized with the ACS Pure Chemistry Award, APS McGroddy Prize for New Materials, Julius Springer Prize for Applied Physics and Materials Research Society Mid-Career Award. He has been elected to the American Academy of Arts and Sciences, National Academy of Sciences (NAS), National Academy of Medicine (NAM) and Foreign Member of Chinese Academy of Sciences.
The Dai Laboratory has advanced the synthesis and basic understanding of carbon nanomaterials and applications in nanoelectronics, nanomedicine, energy storage and electrocatalysis.
The Dai Lab pioneered some of the now-widespread uses of chemical vapor deposition for carbon nanotube (CNT) growth, including vertically aligned nanotubes and patterned growth of single-walled CNTs on wafer substrates, facilitating fundamental studies of their intrinsic properties. The group developed the synthesis of graphene nanoribbons, and of nanocrystals and nanoparticles on CNTs and graphene with controlled degrees of oxidation, producing a class of strongly coupled hybrid materials with advanced properties for electrochemistry, electrocatalysis and photocatalysis. The lab’s synthesis of a novel plasmonic gold film has enhanced near-infrared fluorescence up to 100-fold, enabling ultra-sensitive assays of disease biomarkers.
Nanoscale Physics and Electronics
High quality nanotubes from his group’s synthesis are widely used to investigate the electrical, mechanical, optical, electro-mechanical and thermal properties of quasi-one-dimensional systems. Lab members have studied ballistic electron transport in nanotubes and demonstrated nanotube-based nanosensors, Pd ohmic contacts and ballistic field effect transistors with integrated high-kappa dielectrics.
Nanomedicine and NIR-II Imaging
Advancing biological research with CNTs and nano-graphene, group members have developed π–π stacking non-covalent functionalization chemistry, molecular cellular delivery (drugs, proteins and siRNA), in vivo anti-cancer drug delivery and in vivo photothermal ablation of cancer. Using nanotubes as novel contrast agents, lab collaborations have developed in vitro and in vivo Raman, photoacoustic and fluorescence imaging. Lab members have exploited the physics of reduced light scattering in the near-infrared-II (1000-1700nm) window and pioneered NIR-II fluorescence imaging to increase tissue penetration depth in vivo. Video-rate NIR-II imaging can measure blood flow in single vessels in real time. The lab has developed novel NIR-II fluorescence agents, including CNTs, quantum dots, conjugated polymers and small organic dyes with promise for clinical translation.
Electrocatalysis and Batteries
The Dai group’s nanocarbon–inorganic particle hybrid materials have opened new directions in energy research. Advances include electrocatalysts for oxygen reduction and water splitting catalysts including NiFe layered-double-hydroxide for oxygen evolution. Recently, the group also demonstrated an aluminum ion battery with graphite cathodes and ionic liquid electrolytes, a substantial breakthrough in battery science.

Professor of German Studies and of Comparative Literature
BioMy research focuses on the long nineteenth century, in particular questions of gender in literature, music and philosophy. My first book, "Zwillingshafte Gebärden": Zur kulturellen Wahrnehmung des vierhändigen Klavierspiels im neunzehnten Jahrhundert (Königshausen & Neumann, 2009), traces four-hand piano playing as both a cultural practice and a motif in literature, art and philosophy (an English edition of the book recently appeared as Four-Handed Monsters: Four-Hand Piano Playing and Nineteenth-Century Culture (Oxford University Press, 2014)). My second book Uncivil Unions - The Metaphysics of Marriage in German Idealism and Romanticism (University of Chicago Press, 2012), explored German philosophical theories of marriage from Kant to Nietzsche. Tristan's Shadow - Sexuality and the Total Work of Art (University of Chicago Press, 2013), deals with eroticism in German opera after Wagner. My most recent academic book, The Dynastic Imagination (University of Chicago Press, 2020) traces the fate of the dynasty in the age of the nuclear family. A comparative and intermedial study of the ballad-form in nineteenth century Europe will appear in 2022 with Oxford University Press. In addition, I have published articles on topics such as fin-de-siècle German opera, women composers in the 19th century, the history of feminist philosophy, the films of Hans-Jürgen Syberberg, film music, literature and scandal, the legacies of Richard Wagner, the cultural use of ballads in the nineteenth century, and writers like Novalis, Stefan George, Walter Benjamin, Sophie Mereau, Theodor Adorno and W.G. Sebald. I also write on popular culture and politics: in this capacity I co-wrote The James Bond Songs: Pop Anthems of Late Capitalism (with Charles Kronengold) and published a German-language essay collection Pop Up Nation (Hanser, 2016). My book What Tech Calls Thinking (Farrar, Straus & Giroux, 2020) has been translated into five languages. I write articles for the Neue Zürcher Zeitung (Switzerland), Frankfurter Allgemeine Zeitung (Germany), Die Zeit (Germany), The Guardian (UK), The Nation, The New Republic, n+1, Longreads and the LA Review of Books.

J. P. Daughton
Professor of History
BioI am an historian of modern Europe and European imperialism with a particular interest in political, cultural, and social history, as well as the history of humanitarianism.
My most recent book, In the Forest of No Joy: The Congo-Océan Railroad and the Tragedy of French Colonialism (W. W. Norton, 2021), tells the story of one of the deadliest construction projects in history. Between 1921 and 1934, French colonial interests recruited -- most often by force -- more than 100,000 men, women, and children to work on a 500-kilometer stretch of rail between Brazzaville and the Atlantic Coast. In the end, tens of thousands of Africans were dead, killed by mistreatment, starvation, and disease. The book painstakingly recounts the experiences of local communities in the face of colonial economic development, considers why the railroad witnessed such extraordinary violence and suffering, and explores the strategies defenders of the train used to justify the loss of so many African lives.
I am also the author of An Empire Divided: Religion, Republicanism, and the Making of French Colonialism, 1880-1914 (Oxford University Press, 2006), a book that tells the story of how troubled relations between Catholic missionaries and a host of republican critics shaped colonial policies, Catholic perspectives, and domestic French politics in the decades before the First World War. Based on archival research from four continents, the book challenges the long-held view that French colonizing and “civilizing” goals were the product of a distinctly secular republican ideology built on Enlightenment ideals. By exploring the experiences of religious workers, one of the largest groups of French men and women working abroad, the book argues that many “civilizing” policies were wrought in the fires of discord between missionaries and anti-clerical republicans – discord that indigenous communities exploited in responding to colonial rule. A CHOICE Outstanding Academic Title, An Empire Divided was awarded the George Louis Beer Prize for the best book in international history from the American Historical Association, as well as the Alf Andrew Heggoy Book Prize from the French Colonial Historical Society.

BioWhat is the origin of mass? Are there other universes with different physical laws?
Professor Dimopoulos has been searching for answers to some of the deepest mysteries of nature. Why is gravity so weak? Do elementary particles have substructure? What is the origin of mass? Are there new dimensions? Can we produce black holes in the lab?
Elementary particle physics is entering a spectacular new era in which experiments at the Large Hadron Collider at CERN will soon shed light on such questions and lead to a new deeper theory of particle physics, replacing the Standard Model proposed forty years ago. The two leading candidates for new theories are the Supersymmetric Standard Model and theories with Large Extra Dimensions, both proposed by Professor Dimopoulos and collaborators.
Professor Dimopoulos is collaborating on a number of experiments that use the dramatic advances in atom interferometry to do fundamental physics. These include testing Einstein’s theory of general relativity to fifteen decimal precision, atom neutrality to thirty decimals, and looking for modifications of quantum mechanics. He is also designing an atom-interferometric gravity-wave detector that will allow us to look at the universe with gravity waves instead of light, marking the dawn of gravity wave astronomy and cosmology.

Assistant Professor of Otolaryngology - Head & Neck Surgery (OHNS)
BioI received my Master’s degree in speech language pathology from Purdue University in 2008. I then completed my Clinical Fellowship Year (CFY) at Indiana University Health – Arnett Hospital in Lafayette, Indiana. Following the completion of my Master’s degree, I remained at Purdue and received my PhD in 2012 in laryngeal physiology with M. Preeti Sivasankar, PhD. I then completed postdoctoral training in the Department of Surgery, Division of Otolaryngology – Head & Neck Surgery at the University of Wisconsin-Madison in the laboratory of Susan L. Thibeault, PhD studying vocal fold biology.
I joined the Stanford faculty in 2014 as an Assistant Professor. My clinical interests include the evaluation and treatment of patients with voice, resonance, airway, and swallowing disorders.
My overarching research goal is to use techniques from the basic sciences and human clinical sciences to improve the prevention and management of voice disorders. My research program is directed at improving our understanding of the biologic barriers essential to vocal fold health. Specifically, I investigate how external factors implicated in the development of voice disorders, such as inhaled pollutants, bacteria, and viruses, compromise the function of the vocal fold epithelial and mucus barriers and how these changes may influence voice production. I am also interested in clinical and quality of life outcomes in patients with voice disorders undergoing surgical or behavioral interventions. My ultimate aim is to utilize my research findings to develop novel interventions to prevent and manage voice disorders.

Assistant Professor of History
BioI am a historian of western Europe and the Mediterranean, primarily during the high and late Middle Ages. Much of my research tries to understand how law and society interact with each other, especially where legal norms conflict with social practices. Another strand of my research explores the history of economic life and economic thought, especially medieval debates over usury and moneylending. I have also written on the circulation of goods, people, and ideas in the medieval Mediterranean.
My current book project (Conflicts of Interest: Jews, Christian Moneylenders, and the Rise of Mass Expulsion in Medieval Europe) uses the banishment of Jewish and Christian moneylenders to explore the rise of mass expulsion as a widespread practice in the later Middle Ages. A second ongoing project examines the ways in which medieval canon law was adapted, reinterpreted, or resisted in local contexts in the thirteenth and fourteenth centuries. The latter builds on Corpus Synodalium, a searchable full-text database of late medieval local ecclesiastical legislation that I have been developing since 2016, with assistance from colleagues around the world.
Born and raised in western Canada, I did my undergraduate and doctoral work at Harvard University, earning an MPhil in Medieval History from the University of Cambridge along the way. Before coming to Stanford, I was a Junior Fellow at the Harvard Society of Fellows.
