    Hyun Suk Park 朴賢淑 (she/her)

    Assistant Professor of East Asian Languages and Cultures

    BioMy primary field of research is Korean literature and culture from the seventeenth through the nineteenth century. As a scholar of Korean literature both in Korean and literary Sinitic (hanmun 漢文) by training, my research is deeply engaged with the East Asian cultural tradition. My research interests include the intersections between literature and performance, the history of gender and sexuality, the comparative history of slavery, and the cultural history of natural disasters in early modern East Asia and beyond.

    My first book manuscript, Precarious Spectacle: Martial Courtesans, State Slavery, and the Ritual Production of Royal Authority in Chosŏn Korea (forthcoming; Harvard University Asia Center, 2027), explores the cultural production of government courtesans (kwan’gi 官妓) at the nexus of the studies of slavery, gender, and performance in Korean literature. In this work, I illuminate how the spectacular performances of courtesans, offered in state events, were involved in the constitution and reproduction of state power of Chosŏn. I also examine how courtesan performances represent state power as multivalent and unstable through the frequent incorporation of heterogeneous elements, as exemplified by martial entertainment offered by cross-dressing courtesans.

    I am currently in the process of designing a new research project that explores the same-sex intimacy created by the practice of letter writing between the literati of Chosŏn and Qing outside of diplomatic venues. I am also developing a long-term research project in environmental humanities that focuses on climate disasters in seventeenth-century East Asia and explores the new methodologies of writing a literary and cultural history that considers climate as an actant.

    Before joining Stanford in 2025, I have taught at UCLA (2018–2025), Seoul National University (2016–2018), and UC Berkeley (2013–2016).

  • Robertson Parkman

    Robertson Parkman

    Other Teaching Staff-Hourly, Pediatrics - Stem Cell Transplantation

    BioMy principal research interests have been the assessment of the immunological consequences of hematopoietic stem cell transplantation including both acute and chronic graft versus host disease and immune reconstitution and the use of hematopoietic stem cell transplantation to treat genetic diseases. My laboratory was the first to suggest that chronic graft versus host disease was an autoimmune disease directed at histocompatibility antigens shared by donors and recipients. The observation leaded to the assessment of the role of thymic dysfunction in the pathogenesis of chronic graft versus host disease. As a pediatric immunologist I have investigated the role of hematopoietic stem cell transplantation initially in the treatment of primary immune deficiency diseases and later the treatment of metabolic diseases, which lead to my involvement in the early gene transfer clinical trials.

  • Jane Parnes

    Jane Parnes

    Professor of Medicine, Emerita

    Current Research and Scholarly InterestsThe lab is studying the mechanisms controlling B cell responsiveness and the balance between tolerance and autoimmunity. B cells deficient in CD72 are hyperresponsive to stimulation through the B cell receptor.

  • Anca M. Pasca, MD

    Anca M. Pasca, MD

    Assistant Professor of Pediatrics

    Current Research and Scholarly InterestsI am a physician-scientist, neonatologist, and stem cell biologist whose research focuses on understanding mechanisms of human brain development, neuroinflammation, and neurological injury using patient-derived stem cell models.
    I was among the early pioneers of three-dimensional human cortical organoid technologies and contributed to development of foundational protocols for generating region-specific human brain organoids from pluripotent stem cells. My work helped establish the feasibility of modeling human brain development and disease using stem cell-derived tissues and has contributed to the widespread adoption of organoid technologies across neuroscience, regenerative medicine, and translational research.
    A major focus of my laboratory is the development of increasingly sophisticated multicellular organoid and assembloid systems that incorporate diverse neuronal and glial populations to model complex human brain circuitry and disease processes. We integrate stem cell biology, organoid engineering, CRISPR-based genome editing, single-cell transcriptomics, epigenomics, high-content imaging, and computational approaches to identify disease mechanisms and therapeutic targets. These technologies have been applied to studies of hypoxic brain injury, 22q11.2 deletion syndrome, Trisomy 21 (Down Syndrome), Trisomy 18, narcolepsy, Alzheimer's and Parkinson's Disease.

  • Sergiu P. Pasca

    Sergiu P. Pasca

    Kenneth T. Norris, Jr. Professor of Psychiatry and Behavioral Sciences and Bonnie Uytengsu and Family Director of the Stanford Brain Organogenesis Program and Senior Fellow, by courtesy, at the Hoover Institution

    Current Research and Scholarly InterestsA critical challenge in understanding the intricate programs underlying development, assembly and dysfunction of the human brain is the lack of direct access to intact, functioning human brain tissue for detailed investigation by imaging, recording, and stimulation.
    To address this, we are developing bottom-up approaches to generate and assemble, from multi-cellular components, human neural circuits in vitro and in vivo.
    We introduced the use of instructive signals for deriving from human pluripotent stem cells self-organizing 3D cellular structures named brain region-specific spheroids/organoids. We demonstrated that these cultures, such as the ones resembling the cerebral cortex, can be reliably derived across many lines and experiments, contain synaptically connected neurons and non-reactive astrocytes, and can be used to gain mechanistic insights into genetic and environmental brain disorders. Moreover, when maintained as long-term cultures, they recapitulate an intrinsic program of maturation that progresses towards postnatal stages.
    We also pioneered a modular system to integrate 3D brain region-specific organoids and study human neuronal migration and neural circuit formation in functional preparations that we named assembloids. We have actively applied these models in combination with studies in long-term ex vivo brain preparations to acquire a deeper understanding of human physiology, evolution and disease mechanisms.
    We have carved a unique research program that combines rigorous in vivo and in vitro neuroscience, stem cell and molecular biology approaches to construct and deconstruct previously inaccessible stages of human brain development and function in health and disease.
    We believe science is a community effort, and accordingly, we have been advancing the field by broadly and openly sharing our technologies with numerous laboratories around the world and organizing the primary research conference and the training courses in the area of cellular models of the human brain.

  • Scott Pearson

    Scott Pearson

    Professor at the Food Research Institute, Emeritus

    BioScott Pearson taught economic development and international trade in the Food Research Institute. Pearson came to Stanford in 1968 and was promoted to Associate Professor with tenure in 1974 and to Professor in 1980. He served as the Food Research Institute’s Associate Director (1977-1984) and Director (1992-1996). Pearson became Professor Emeritus in 2002. In retirement, Pearson has lectured on 67 travel/study programs for the Stanford Alumni Association and 121 educational travel trips in total, visiting all seven continents.

    Pearson grew up in Baraboo, Wisconsin and graduated from the University of Wisconsin with a Bachelor of Sciences degree in American history in 1961. Between 1961 and 1963, he was one of the first Peace Corps Volunteers – serving as a secondary school teacher in Northern Nigeria. Pearson’s marriage to Sandra Anderson in Lagos, Nigeria in 1962 was the first wedding in the Peace Corps.

    Pearson decided to pursue a career in academia, specializing in international development. He spent one year in Bologna, Italy and another in Washington, D.C. to earn a Master of Arts degree at the Johns Hopkins School of Advanced International Studies in 1965. Pearson then earned a doctorate in economics at Harvard University in 1968. He wrote his dissertation on the impact of petroleum exports on Nigerian development under the direction of Albert Hirschman and revised his thesis for his first book, Petroleum and the Nigerian Economy (Stanford University Press, 1970).

    Pearson began his empirical research in Nigeria (1961-69) and Ghana (1970-78). He later focused on Indonesia (1979-2004), Portugal (1981-95), and Kenya (1986-96). Pearson’s professional work abroad combined research (in collaboration with local university or government researchers), teaching (of short courses to transfer methods of field research and analysis), and policy analysis (to provide policy advice to government officials).

    During most years, Pearson taught during two Stanford quarters and spent five months working abroad. In 1978, Pearson received the Dean’s Award for Teaching in Stanford’s School of Humanities and Sciences.

    Pearson’s research focused on food and agricultural policy analysis, especially links among price, macroeconomic, and investment policies. He also worked on food price stabilization, trade and exchange rate policies, and social benefit-cost analysis. Wally Falcon, Peter Timmer, and Pearson collaborated for many years in Indonesia and co-authored Food Policy Analysis (The Johns Hopkins University Press, 1983), which received the Award for Professional Excellence, Quality of Communication in 1984 from the American Agricultural Economics Association and was translated into five languages.

    In 1982, Eric Monke and Pearson began developing the Policy Analysis Matrix (PAM) approach to integrate policy and project analysis. PAM is a marriage of benefit-cost analysis and economic policy analysis in a matrix framework. Monke and Pearson explained the PAM approach in The Policy Analysis Matrix for Agricultural Development (Cornell University Press, 1989). Most of the 12 books that Pearson co-authored are applications of the PAM. Pearson presented PAM short-courses in China, Indonesia, Italy, Japan, Kenya, the Philippines, Portugal, Russia, Thailand, Washington (the World Bank), and Zimbabwe.

    Pearson was a member of numerous university committees and served on the Board of Trustees Committee on Finance and Administration and the Faculty Senate. Pearson and his wife, Sandra, were Faculty Residents in undergraduate dormitories at Stanford for five years (Serra House, 1968-1969 and 1977-1978, Madera House, 1978-1980, and Potter House, 1983-1984). Sandra Pearson later served as Principal of Palo Alto High School (1987-1994 and 2002-2004), and in 2004 she won the Tall Tree Award, sponsored by the Palo Alto Chamber of Commerce and the Palo Alto Weekly.

  • Robert Pecora

    Robert Pecora

    Professor of Chemistry, Emeritus

    Current Research and Scholarly InterestsThe development of the basic principles behind the dynamic light scattering (DLS) technique and its application to a wide variety of liquid systems is one of Pecora's outstanding contributions to physical chemistry. DLS is now an indispensable tool in the repertoire of polymer, colloid and biophysical chemists. It is generally accepted to be one of the best methods for measuring the mutual diffusion coefficients and, in dilute systems, the hydrodynamic sizes of polymers and particulates in solution or suspension. It is widely used, among other things, for studying size distributions of polymer and colloid dispersions; for testing theories of polymer dynamics in dilute and concentrated systems; and for studying interactions between macromolecules and colloidal particles in liquid dispersions. The basic work that established the foundation of this technique was done in the 1960s. Pecora has revisited this area over the years-formulating theories, for instance, of scattering from hollow spheres, large cylindrically symmetric molecules and wormlike chains.

    An experimental program began in the early seventies resulted in a now classic series of studies on the rotational dynamics of small molecules in liquids. This work, utilizing mainly depolarized DLS and carbon 13 nuclear magnetic relaxation, has had a wide impact in the area of liquid state dynamics.

    It was also during this period that the theoretical foundation for the fluorescence correlation spectroscopy technique (FCS) was formulated. Because of recent advances in equipment and materials, this technique has recently been revived and is now a powerful tool in biophysics.

    The experimental and theoretical techniques developed for the study of the dynamics of relatively simple small molecule liquids have been used to investigate more complex systems such as the rotation of small molecule solvents in glassy and amorphous polymers. The resonance- enhanced depolarized light scattering technique was also developed in this period.

    Extensive studies using depolarized dynamic light scattering (using the Fabry-Perot interferometer) as well as photon correlation spectroscopy, NMR, FCS and small angle X-ray scattering to the dynamics of oligonucleotides have determined the hydrodynamic diameter of DNA and the internal bending angles of the bases. They also provided support for relations relating hydrodynamic parameters to molecular dimensions for short rodlike molecules and “polyelectrolyte effects” on the translational and rotational motions of these highly charged molecules.

    A major area of experimental and theoretical study has been the study of the dynamics of rigid and semirigid rodlike polymers in both dilute and semidilute dispersions. The work on translation and rotation of poly (-benzyl-L-glutamate) in semidilute solution is a foremost early work in this area.

    The Pecora group has synthesized and studied the dynamics of model
    rigid rod/sphere composite liquids. Studies of the translation of dilute spheres through solutions of the rods as functions of the rod and sphere sizes and the rod concentrations have provided the stimulus for more experiment and theoretical work in this area. Transient electric birefringence decay studies of the rotation of dilute rigid rod polymers in suspensions of comparably sized spherical particles have revealed scaling laws for the rod rotation.

    A unique feature of part of this work on rigid and semirigid rodlike polymers is the utilization of genetic engineering techniques to construct a monodisperse, homologous series of DNA restriction fragments. These biologically-produced fragments have served as well-characterized model macromolecules for solution studies of the dynamics of semirigid rodlike polymers.

    The well-regarded book of Pecora and Berne on dynamic light scattering, first published in 1976, has become a major reference work. It is now a Dover paperback.
