Christopher Marshall

Assistant Professor, Physics and Astronomy

Christopher Marshall joins the faculty after serving as a Chamberlain Fellow at Lawrence Berkeley National Laboratory in California. Previous to that, he was a fellow at Fermilab in Illinois. He first came to the 91×ÔÅÄÂÛ̳ in 2010 as a graduate student.

Marshall’s research focus is fundamental particle physics; in particular, neutrinos, which are subatomic particles with a mass close to zero. Marshall is currently part of an international team designing and developing the Deep Underground Neutrino Experiment (DUNE), which will detect the oscillations of neutrinos and antineutrinos as they travel 1,300 kilometers through the earth from Fermilab in Illinois to an underground laboratory in South Dakota. The goal of the project is to learn whether neutrinos change types in ways that offer clues as to why the universe is made of matter instead of antimatter. Marshall also studies the ways in which neutrinos interact with ordinary matter, and he has been involved in other national neutrino research collaborations.

Marshall’s work has appeared in Physical Review Letters and other peer-reviewed journals.

At 91×ÔÅÄÂÛ̳, Marshall will teach undergraduate physics courses, in addition to conducting research.

Elise Piazza

Assistant Professor, Brain and Cognitive Sciences

Elise Piazza joins 91×ÔÅÄÂÛ̳’s faculty as an assistant professor in the Department of Brain and Cognitive Sciences, after serving as a postdoctoral fellow at Princeton University.

Using behavioral and neuroimaging approaches, Piazza studies how humans communicate, especially through sounds such as speech and music. From the perspective of listening, Piazza investigates how the auditory system uses a mechanism called statistical summary to compress complex sensory information into more concise representations, allowing humans to efficiently process sound. From the perspective of production, she investigates how speakers adapt their voices to make it easier for different audiences to understand them. To link both sides of communication, her recent research has focused on how our brains and behaviors become coupled to other people’s when we listen to and learn from each other.

Piazza’s research has been funded by organizations including the National Institutes of Health and the Grammy Museum. Her work has been published in peer-reviewed journals, including Current Biology and Psychological Science and has been covered by national media outlets, including PBS, Science Friday, and the Washington Post.

In addition to her research, Piazza will be teaching the course Music and the Mind in spring 2021.

Ariel Zylberberg

Assistant Professor, Brain and Cognitive Sciences

Ariel Zylberberg joins the faculty as an assistant professor in the Department of Brain and Cognitive Sciences. Previously, he was a research specialist at Howard Hughes Medical Institute and an adjunct associate research scientist at the Mortimer B. Zuckerman Mind Brain Behavior Institute at Columbia University.

Zylberberg’s research focuses on how people make decisions that require planning and reasoning. Complex decisions can often be broken down into a series of simpler operations, and Zylberberg’s research identifies and characterizes the elementary operations. Zylberberg and the members of his lab design and study behavioral experiments in which people make decisions involving different levels of complexity. They develop mathematical theories and models to explain behavioral observables—such as errors, reaction times, and confidence judgments—and physiological responses, such as pupil size. Zylberberg also collaborates with experimental laboratories to identify the neural mechanisms underlying decision making in nonhuman animals. His long-term goal is to develop a theory that explains how people build internal models of the environment and of themselves and how these models are used in decision making.

Zylberberg’s research has been published in Science, Nature Human Behavior, Neuron, and otherpeer-reviewed journals.

In addition to conducting research, Zylberberg will teach graduate and undergraduate courses on decision making and neuroeconomics.
