Carl Wieman
Cheriton Family Professor and Professor of Physics and of Education, Emeritus
Current Research and Scholarly InterestsThe Wieman group’s research generally focuses on the nature of expertise in science and engineering, particularly physics, and how that expertise is best learned, measured, and taught. This involves a range of approaches, including individual cognitive interviews, laboratory experiments, and classroom interventions with controls for comparisons. We are also looking at how different classroom practices impact the attitudes and learning of different demographic groups.

Herman Winick
Professor of Applied Physics (Research), Emeritus
BioBorn and educated in New York City, he received his AB (1953) and his PhD (1957) from Columbia University. Following a postdoc position at the University of Rochester (1957-59) he continued work in high energy physics and accelerator development at the Cambridge Electron Accelerator at Harvard University (1959-73), serving as Assistant Director. He came to Stanford in 1973 to lead the technical design of the Stanford Synchrotron Radiation Project (SSRP), now SSRL, and served as Deputy Director of the laboratory until his semi-retirement in 1998 (www-ssrl.slac.stanford.edu). He has taught physics at Columbia, Rochester, Harvard, MIT, Northwestern, University of Massachusetts, and Stanford. His 1970’s and 1980’s research developing periodic magnet systems (wigglers and undulators), had a major impact on synchrotron radiation sources and research facilities at Stanford and around the world. Beginning in 1992 he made major contributions to initiating and developing the Linac Coherent Light Source (LCLS), the world’s first X-ray Free Electron Laser. Starting operation in 2009, the LCLS has shifted the major SLAC focus from high energy physics to x-ray sources and research. In 1997 he suggested SESAME, a synchrotron light source involving 9 countries in the Middle East. He has played a major role in the development of this project, on track to start research in 2016 (www.sesame.org.jo). He is now promoting a similar project in Africa. Throughout his adult life he has been an activist in helping dissidents and protecting academic freedom and human rights.

Yingtong "Amanda" WU
Lecturer
BioI am a plant ecologist, botanist, and naturalist. I am broadly interested in microbial ecology, canopy ecology, and their intersections with the traditional ecological knowledge (TEK) of Native Americans. I completed my Ph.D. in Ecology, Evolution, and Systematics with the Ricklefs Lab at the University of Missouri - St. Louis. I am currently a postdoc researcher at the Fukami Lab, Stanford University, where I will be applying my analytical skills in microbial DNA sequencing to understand: (1) the community assembly of monkeyflower nectar microbes and (2) the effects of wildfires and prescribed burning on microbial communities associated with California oaks.
My previous and ongoing research projects include:
FIRES AND TRADITIONAL ECOLOGICAL KNOWLEDGE
SPECIES RANGE SIZES AND SPECIES RARITY
SOIL MICROBIAL COMMUNITIES
SPECIES DELIMITATION AND GENE FLOW

Mason Yearian
Professor of Physics, Emeritus
BioMason received his PhD in physics at Stanford University. Later, he served as an assistant professor, associate professor, and professor at Stanford. Past research includes developing detectors for X-ray and gamma ray astronomy, and work on the GRO/EGRET experiments. Mason also developed a computer-based curriculum for teaching introductory physics courses in high schools and universities.

On Leave from 10/01/2024 To 12/31/2024Current Research and Scholarly InterestsMy research group is exploring a variety of topics that range from the basic understanding of chemical reaction dynamics to the nature of the chemical contents of single cells.
Under thermal conditions nature seems to hide the details of how elementary reactions occur through a series of averages over reagent velocity, internal energy, impact parameter, and orientation. To discover the effects of these variables on reactivity, it is necessary to carry out studies of chemical reactions far from equilibrium in which the states of the reactants are more sharply restricted and can be varied in a controlled manner. My research group is attempting to meet this tough experimental challenge through a number of laser techniques that prepare reactants in specific quantum states and probe the quantum state distributions of the resulting products. It is our belief that such state-to-state information gives the deepest insight into the forces that operate in the breaking of old bonds and the making of new ones.
Space does not permit a full description of these projects, and I earnestly invite correspondence. The following examples are representative:
The simplest of all neutral bimolecular reactions is the exchange reaction H H2 -> H2 H. We are studying this system and various isotopic cousins using a tunable UV laser pulse to photodissociate HBr (DBr) and hence create fast H (D) atoms of known translational energy in the presence of H2 and/or D2 and using a laser multiphoton ionization time-of-flight mass spectrometer to detect the nascent molecular products in a quantum-state-specific manner by means of an imaging technique. It is expected that these product state distributions will provide a key test of the adequacy of various advanced theoretical schemes for modeling this reaction.
Analytical efforts involve the use of capillary zone electrophoresis, two-step laser desorption laser multiphoton ionization mass spectrometry, cavity ring-down spectroscopy, and Hadamard transform time-of-flight mass spectrometry. We believe these methods can revolutionize trace analysis, particularly of biomolecules in cells. -
Alfred Zong
Assistant Professor of Physics and Applied Physics
BioI am an assistant professor in the Departments of Physics and of Applied Physics, and my group focuses on the study of light-induced non-equilibrium phenomena in quantum materials. To capture the ultrafast dynamics on the nanoscale, we develop a variety of techniques such as ultrafast electron diffraction and microscopy, attosecond transient absorption spectroscopy, and coherent diffraction imaging. These time-resolved probes are integrated with a complex sample environment such as in-situ strain and electrostatic gating in order to design, discover, and understand non-equilibrium phases of quantum materials.
We are seeking motivated undergraduates, graduate students, and postdocs to join the group. Please email me directly to discuss opportunities.
