Rate My Professor Binzheng ZHANG

Professor Binzheng Zhang serves as Acting Associate Head (Teaching) and Associate Professor in the Department of Earth and Planetary Sciences, Faculty of Science, at the University of Hong Kong. He also holds an Associate Professor position by courtesy in the Department of Physics. Zhang obtained his BE in electrical engineering in 2005 and MEng in 2007 from Zhejiang University, followed by a PhD in engineering from Dartmouth College in 2012. He joined the University of Hong Kong in 2018 as Assistant Professor and progressed to his current role. His doctoral advisor was William Lotko, Emeritus Professor at Dartmouth College.

Zhang's research specializes in planetary magnetospheres, space plasma physics, and the development of advanced high-order numerical schemes for magnetohydrodynamics (MHD) and hydrodynamics equations. He investigates system-level interactions between solar wind, planetary magnetospheres, ionospheres, and upper atmospheres, with applications to space weather forecasting and mission design. He created the GAMERA code, a general-purpose high-performance MHD solver for simulating planetary space environments including those of Venus, Earth, Mars, Jupiter, and Saturn. His Jupiter magnetosphere model, integrated with Juno mission observations, resolved longstanding questions about its magnetic field topology and auroral structures. Zhang collaborates with scientists from the Chinese Academy of Sciences and China National Space Administration on the Tianwen-4 mission to Jupiter and Uranus, planned for 2030. Key publications include 'How Jupiter’s unusual magnetospheric topology structures its aurora' (Science Advances, 2021), 'GAMERA: A three-dimensional finite-volume MHD solver for non-orthogonal curvilinear geometries' (The Astrophysical Journal Supplement Series, 2019), 'Ionospheric control of magnetotail reconnection' (Science, 2014), and 'Magnetosphere sawtooth oscillations induced by ionospheric outflow' (Science, 2011). His contributions earned the HKU Outstanding Young Researcher Award (2022), NSFC Excellent Young Scientists Fund (Hong Kong and Macau, 2019), RGC Research Fellow Scheme (2025), and NASA Space Grant Award (2014).
