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
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. -

Michael Peskin
Professor of Particle Physics and Astrophysics, Emeritus
BioI am a theoretical physicist interested in elementary particles and the fundamental interactions. My main research interests are:
* consequences of the "Standard Model of particle physics"
* precision study of the heaviest known elementary particles - the W and Z bosons, the top quark, and the Higgs boson - to search for clues to new fundamental interactions beyond the Standard Model
* models of such new interactions, especially models with composite or strongly interacting Higgs bosons
* models for the particle that composes the dark matter of the universe
I am the author of a leading theoretical textbook in this area, "An Introduction to Quantum Field Theory", with Daniel Schroeder. Recently, I have written another textbook that emphasizes our experimental knowledge, "Concepts of Elementary Particle Physics".

Claudia Katharina Petritsch
Associate Professor (Research) of Neurosurgery
Senior Research Scientist, Adult NeurologyCurrent Research and Scholarly InterestsThe Petritsch lab broadly investigates underlying causes for the intra-tumoral heterogeneity and immune suppression in brain tumors from a neuro-developmental perspective. Defective cell fate decisions fuel the intra-humoral heterogeneity and plasticity in human brain tumors and may contribute to immune suppression. We use patient-derived models as avatars to study how brain cells control the fate of their progeny, whereby we unravel novel points of vulnerabilities in brain tumor cells.

Vahe Petrosian
Professor of Physics and of Applied Physics
BioHow do things evolve in the universe? How are particles accelerated in the universe?
Professor Petrosian’s research covers many topics in the broad area of theoretical astrophysics and cosmology, with a strong focus on high-energy astrophysical processes.
Cosmological studies deal with global properties of the universe, where the main focus is the understanding of the evolution of the universe at high redshifts, through studies of the evolutions of population of sources such as galaxies and quasars or active galactic nuclei, gamma-ray bursts, using new statistical techniques developed in collaboration with Prof. B. Efron of the Department of Statistics. Another area of research is the use of gravitational lensing in measuring mass in the universe.
High-energy astrophysics research involves interpretation of non-thermal astronomical sources where particles are accelerated to very high energies and emit various kinds of radiation. These processes occur on many scales and in all sorts of objects: in the magnetosphere of planets, in the interplanetary space, during solar and stellar flares, in the accretion disks and jets around stellar-size and super-massive black holes, at centers of galaxies, in gamma-ray bursts, in supernovae, and in the intra-cluster medium of clusters of galaxies. Plasma physics processes common in all these sources for acceleration of particles and their radiative signature is the main focus of the research here. -

Suzanne Pfeffer
Emma Pfeiffer Merner Professor of Medical Sciences
Current Research and Scholarly InterestsThe major focus of our research is to understand the molecular basis of inherited Parkinson's Disease (PD). We focus on the LRRK2 kinase that is inappropriately activated in PD and how it phosphorylates Rab GTPases, blocking the formation of primary cilia in specific regions of the brain. The absence of primary cilia renders cells unable to carry out Hedgehog signaling that is critical for neuroprotective pathways that sustain dopamine neurons.

Trung Hoang Minh Pham
Assistant Professor of Pediatrics (Infectious Diseases) and of Microbiology and Immunology
Current Research and Scholarly InterestsUncovering mechanisms of tissue immunity and immunophysiology during persistent infection
The immune system safeguards the health of complex organisms by rapidly eliminating invading pathogens, curbing infection-induced tissue disruptions, and maintaining tissue homeostasis. Many bacterial pathogens evade host antimicrobial mechanisms and persist in infected tissues at low levels for long periods of time even in the presence of innate and adaptive immune resistance. During persistent infection, the immune system simultaneously orchestrates antimicrobial responses to contain the pathogen, repairs damaged tissue, regulates nutrient resources, and maintains other tissue physiological functions to ensure host survival. Failure of any of these tasks leads to uncontrolled infection, devastating disease, and even death. The goals of our research are to understand:
1)What are the innate and adaptive immune cellular mechanisms that contain pathogens during persistent infection?
2)How are tissue physiological functions, such as tissue repair and nutrient regulation, maintained during persistent infection?
3)How do pathogens survive innate and adaptive antimicrobial mechanisms in infected tissues?
4)How does persistent infection impact host immunity to secondary infections of a similar or different pathogen?
Through investigating these fundamental questions, we may be able to decode the underlying cellular and molecular mechanisms that can be harnessed to eradicate infections, promote tissue resilience, and restore health after an infectious insult. We integrate immunology, tissue biology, microbiology, and genetics to uncover the mechanisms of tissue immunity and immunophysiology during persistent infection from the molecular to organismal level.
Current areas of research:
•Development, maintenance, and plasticity of macrophage functional diversity in infected tissue
•Tissue repair and nutrient regulation during persistent infection
•Cellular dynamics and bacterial persistence in lymphoid organs -
