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".

Eliane Petersohn
Ph.D. Student in Geological Sciences, admitted Autumn 2022
BioI grew up in Curitiba, a city in southern Brazil, and, moved to Rio de Janeiro to join the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) years ago.
I have a strong grasp of the oil and gas industry, where I have been working for more than 15 years. I have a bachelor’s and master's degree in geology from the Federal University of Parana, Brazil and, I have become a public servant of the ANP, where I have held different technical and managerial positions. I spent these past 15 years working on the ANP’s large-scale strategic projects, conducting a geological evaluation for Brazil’s bidding rounds, and developing a multiyear geological and geophysical data acquisition plan for the Agency. I was also responsible for coordinating the first phase of the onerous assignment process, which authorized the Brazilian Government to onerously assign to NOC Petrobras up to 5 billion barrels of oil. I have also been directly involved in the location of two wells, which discovered two of the country's largest oil fields (Buzios and Mero fields). As a geologist researcher, my main objective aims at acquiring capabilities and developing the knowledge required to manage reservoirs to maximize oil recovery and extend the lifespan of oil fields as well as acquire a solid understanding of oil reservoir management to bring innovative knowledge to Brazil and help create guidelines to monitor oil field development and production in my country. -

Forest Olaf Peterson, Ph.D.
Research Affiliate, Civil and Environmental Engineering
Staff, Civil and Environmental EngineeringBioAs a staff research affiliate, I bring both blue-collar and white-collar perspectives to my role as a scholar of infrastructure.
For seven years, I was a concrete laborer on large infrastructure projects with the Laborers’ International Union of North America. Those years taught me social and environmental dimensions from the ground up.
My fellow laborers wanted to work safely. However, though skilled, we often did not have the information to succeed without unnecessary hardship, for example, on a large highway project we could have worked on another task while a broken piece of equipment was repaired, however, neither the crew nor our supervisors had access to a task schedule to see that (there was a schedule, it was just permission that was missing -- though even with permission the schedule was your typical P6 Gantt which even at best wouldn't have been informative). As a result, our supervisors forced us to continue work loading miles of heavy concrete barriers with a damaged loader. Our choices were to work, quit, or be fired; we were not the operator of the loader, we were the ground crew [2023 Edit: we should have called our Union]. Eventually, a two-ton barrier dropped and hit something that flipped it over where it came to rest just inches above my chest. My fellow workers celebrated my life. One cried in memory of a recent work fatality. We were told to get back to work.
The futility of the situation has left a lasting impression.

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.
