Ho-Kwang (Dave) Mao (born June 18, 1941) is an eminent American geologist and Staff Scientist at the Geophysical Laboratory of the Carnegie Institution for Science.


Mao's hometown is Jiangshan of Zhejiang Province, China. Mao's father the Lieutenant General Mao Sen (毛森), was a high-ranked official of the intelligence department of the Republic of China. Mao Sen is among the so-called "Three Maos" or "One Dai Three Maos" (the other two Maos are Mao Wanli (毛万里) and Mao Renfeng (毛人凤); the Dai is Dai Li (戴笠), all the four came from Jiangshan), which were the core intelligence crew of Chiang Kai-shek.


Mao was born in Shanghai in 1941. When Mao was seven-years old, Mao moved to Taiwan with his family. Mao received his BS from National Taiwan University in 1963. Mao further pursued his studies in the United States, and obtained MS in 1966 and PhD in 1968 from the University of Rochester, Rochester NY.

From 1968-1972, Mao did his postdoctoral research at the Geophysical Laboratory of the Carnegie Institution of Washington (CIW). From then on Mao has spent his career at Geophysical Laboratory as a Senior Staff scientist.


Mao is one of the most prolific users of the diamond anvil cell for research at high pressures. Although at the time the claim was controversial,[1] his work with Peter M. Bell[2] is now generally accepted as being the first verified static pressure in excess of 1 Megabar.
