Cheng has been at the forefront of the development of uranium series technology for the past three decades.    

    

His most well-known technical achievement is the improvement of uranium series dating techniques in 231Pa and 230Thdating systematics, including the re-determination of 230Th and 234Uhalf-lives, which have been widely accepted and used in the uranium-series dating field.    

   

He has developed internationally-leading uranium series mass spectrometry measurement technology, provided many important and accurate absolute time scales of late Quaternary climate change, and accurately measured trace elements and their isotopes in geological samples such as seawater. These techniques are widely used in the study of many fundamental areas in paleoclimatology, paleooceanography, and global climate change research.    

   

Cheng is also an internationally renowned expert in stalagmite paleoclimate research thanks to many breakthrough discoveries.
