C.K. Shum is a professor and Distinguished University Scholar, Division of Geodetic Science, School of Earth Sciences, at The Ohio State University. He is a fellow of the American Association for the Advancement of Science (AAAS), and a fellow of the International Association of Geodesy (IAG).

Shum has received numerous awards including the 2012 Vening Meinesz Medal from the European Geosciences Union for distinguished research in Geodesy applied to sea-level science. He served as a lead author for the Intergovernmental Panel for Climate Change (IPCC) Fourth Assessment Report (AR4), Working Group I, The Physical Science Basis. This contribution resulted in the 2007 Nobel Peace Prize jointly awarded to IPCC and Al Gore, Jr. 

Shum and his group focus on scientific research relates to the quantification of 20th Century and present-day global sea-level rise due to various geophysical sources, including anthropogenic climate-change. He specializes in satellite geodesy, precision satellite orbit determination, temporal gravity field and tide modeling, and their cross-disciplinary science and applications to oceanography, hydrology, geodynamics, ice mass balance, GNSS meteorology and space physics. 

Shun is principal investigator for the NSF-funded Belmont Forum/IGFA, G8, Project, Bangladesh Delta: Assessment of the Causes of Sea-level Rise Hazards and Integrated Development of Predictive Modeling Towards Mitigation and Adaptation (BanD-AID) (ICER-1342644), http://Belmont-SeaLevel.org. The project produced an award-winning documentary, Bay of Hope, Production of 19 Film Factory and Faisal Hossain in 2014, which is widely distributed and in English, Bengali, German and French.

Shum has published more than 300 refereed journal articles and book chapters, with a Google Scholar Citation index of 12,513, H-index: 53, and i-10 Index: 186. 

His work has been covered by New York Times, Physics Today, Sky & Telescope Radio Show, Discoveries and Breakthroughs Inside Science TV, Science News, Science Daily, Scientific American, Soundings magazine, Deccan Chronicle, La Figaro, MSNBC.com, Tomorrow Focus Portal GmbH, Axel Springer AG, Televisión Española, Neue Zürcher Zeitung, Zurich, Columbus Dispatch, American Geophysical Union, Ohio State University press, and other news organizations.
