Assistant Professor of Applied Physics
BioBenjamin Good is a theoretical biophysicist with a background in experimental evolution and population genetics. He is interested in the short-term evolutionary dynamics that emerge in rapidly evolving microbial populations like the gut microbiome. Technological advances are revolutionizing our ability to peer into these evolving ecosystems, providing us with an increasingly detailed catalog of their component species, genes, and pathways. Yet a vast gap still remains in understanding the population-level processes that control their emergent structure and function. Our group uses tools from statistical physics, population genetics, and computational biology to understand how microscopic growth processes and genome dynamics at the single cell level give rise to the collective behaviors that can be observed at the population level. Projects range from basic theoretical investigations of non-equilibrium processes in microbial evolution and ecology, to the development of new computational tools for measuring these processes in situ in both natural and experimental microbial communities. Through these specific examples, we seek to uncover unifying theoretical principles that could help us understand, forecast, and eventually control the ecological and evolutionary dynamics that take place in these diverse scenarios.

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.

Current Research and Scholarly InterestsJon's group focuses on exploring synthetic quantum matter using the unique tools available through quantum and classical optics. We typically think of photons as non-interacting, wave-like particles. By harnessing recent innovations in Rydberg-cavity- and circuit- quantum electrodynamics, the Simonlab is able to make photons interact strongly with one another, mimicking collisions between charged electrons. By confining these photons in ultra-low-loss metamaterial structures, the teams "teach" the photons to behave as though they have mass, are in traps, and are experiencing magnetic fields, all by using the structures to tailor the optical dispersion. In total, this provides a unique platform to explore everything from Weyl-semi-metals, to fractional quantum hall puddles, to Mott insulators and quantum dots, all made of light.
The new tools developed in this endeavor, from twisted fabry-perot resonators, to Rydberg atom ensembles, Floquet-modulated atoms, and coupled cavity optical mode converters, have broad applications in information processing and communication. Indeed, we are now commissioning a new experiment aimed at interconverting optical and mm-wave photons using Rydberg atoms inside of crossed optical and superconducting millimeter resonators as the transducer.

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.
