Dr Ratna is a senior scientist in the Office of Climate Research and Services, India Meteorological Department (IMD), Pune. He has an M.Sc. in Oceanography, an M.Tech. in Atmospheric Sciences, and a Ph.D. in Meteorology. His research interest is in the role of the ocean on climate variability ranging from interannual to multidecadal time scales and diagnosing the physical mechanisms.

Dr. Zhang is a Research Scientist at the South China Sea Institute of Oceanology, Chinese Academy of Sciences. His research primarily focuses on the dynamics of large-scale atmosphere-ocean interactions, exploring their pivotal role in shaping natural climate variability, including phenomena like the El Niño-Southern Oscillation. Additionally, he also investigates the projected changes in the global climate system driven by anthropogenic emissions of greenhouse gases.

Robb Jnglin Wills leads the Climate Dynamics Group at ETH Zurich. He obtained his PhD in 2016 from the California Institute of Technology and had research appointments at ETH Zurich, University of Washington, and the National Center for Atmospheric Research before his appointment as assistant professor at ETH in 2023. Robb and his group use a combination of climate modeling, physics-based theoretical understanding, and data science methods to pursue research on a broad range of topics in climate science.
