Kim Cobb is the Georgia Power Chair and Professor in the School of Earth and Atmospheric Sciences at Georgia Tech. She is the Director of the Global Change Program at Georgia Tech, and serves as the ADVANCE Professor for diversity, equity, and inclusion for the College of Sciences. In her climate research, she uses observations of past and present climate to advance our understanding of future climate change impacts, with a focus on climate extremes and coastal flood hazards. She received her B.A. from Yale University in 1996, and her Ph.D. in Oceanography from the Scripps Institute of Oceanography in 2002. In her research, Kim has sailed on oceanographic cruises and led caving expeditions in the Borneo rainforests. She received a NSF CAREER Award, a Presidential Early Career Award for Scientists and Engineers, and the Hans Oeschger Medal from the European Geosciences Union in 2019. She is a Lead Author for the IPCC Sixth Assessment Report, due out in 2021. As a mother to four, Kim is a strong advocate for women in science, and champions diversity and inclusion in all that she does. She is also devoted to the communication of climate change to the public through media appearances, public speaking, and social media channels, and enjoys frequent exchanges with policymakers about climate impacts and solutions.

Hussein Sayani’s research focuses on developing records of past ocean temperature, salinity, and wind variability in the tropical Pacific that help inform our understanding of how and why climate has changed in the past and how it might change in the future.

Rachel Walter

Research Associate

2020 B.S. Earth and Atmospheric Sciences, Georgia Tech


Rachel is recent graduate from the School of Earth and Atmospheric Science. She is working with PAGES CoralHydro2k to develop the CoralHydro2k database, a global collection of published coral oxygen isotope and trace element records. She is also involved in efforts to investigate the impacts of calibration methodology on coral-based temperature reconstructions.
