Dimitrios Psaltis

Professor

I am a professor of Physics at Georgia Tech. I use advanced computational techniques, hybrid computer architectures, and innovative algorithms to answer fundamental questions related to the observational appearance of black holes, the properties of magnetohydrodynamic turbulence, and the interaction of matter with radiation in extreme conditions.

I am a founding member of the Event Horizon Telescope, the international mm-VLBI experiment that has taken the first picture of a black hole with the horizon-scale resolution, and served for three years (2016-2019) as the Project Scientist of the collaboration.

Before moving to Georgia Tech in 2022, I was a professor of Physics and Astronomy at the University of Arizona and the Chair of the Theoretical Astrophysics Program there.

Feryal Özel

Chair; School of Physics

Professor

Feryal Ozel is the Chair and Professor in the School of Physics at Georgia Institute of Technology. Her research in astrophysics focuses on theoretical and computational studies of the properties, formation, and environments of black holes and neutron stars. She developed new techniques to determine the properties of neutron star surfaces and interiors. She made predictions of black hole images that guided the development of the Event Horizon Telescope (EHT) and helped constrain physics beyond General Relativity.

Ozel is a founding member of the Event Horizon Telescope collaboration, a former member of the EHT Science Council and lead of the Modeling Working Group. In 2022, she led the announcement of the first image of the black hole at the center of the Milky Way Galaxy. She was co-chair of NASA’s Next Generation Large Mission Concept Study for the Lynx X-ray Observatory and has served for three years as chair of NASA’s Astrophysics Advisory Committee. Prior to joining Georgia Tech, she was a Professor of Astronomy and Physics and the Associate Dean for Research at the University of Arizona

Yiyi He

Assistant Professor

Yiyi He is an assistant professor in the School of City and Regional Planning (SCaRP) at the College of Design at Georgia Tech. Her research centers on the interdisciplinary fields of urban planning, GIScience, climate science, and artificial intelligence. She is interested in building a better understanding of the uncertainty and asymmetric impacts of climate-change-induced extreme weather events (e.g., flooding, wildfires, extreme heat) on critical components of the built environment (e.g., lifeline infrastructure networks, vulnerable neighborhoods). She leverages data-driven approaches, such as GIS, network science, hyperspectral remote sensing, machine learning, and spatial statistics to tackle complex challenges in climate change and resilience research and to inform more intelligent planning and policy directives.

Her previous work involves using 3D hydrodynamic flood models to simulate flooding under different climate change scenarios and analyze the impact of both coastal and inland flooding on critical infrastructure networks. She received her bachelor’s degree from Nanjing University and her master’s and Ph.D. degree from UC Berkeley.
