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. -

Kate Petrova
Ph.D. Student in Psychology, admitted Autumn 2021
BioKate Petrova is a PhD student at the Stanford Psychophysiology Laboratory. In her research, Kate applies the tools of computational cognitive science to answer fundamental questions in affective science. She is particularly interested in constructing formal models of emotions and their roles in decision-making. In her dissertation, Kate is using a combination of computational modeling, qualitative methods, eye-tracking, and behavioral experiments to understand how people learn from regret. Kate earned her A.B. in Psychology from Bryn Mawr College and spent several years working on the Harvard Study of Adult Development before joining SPL.
