# Paul Chien

Paul Kwan Chien (born 1 January 1947) is a Chinese-American biologist known for his research on the physiology and ecology of intertidal organisms and his support for intelligent design.

## Biography

Chien was born on 1 January 1947 in Hong Kong and earned bachelor's degrees in Biology and Chemistry from Chung Chi College of the Chinese University of Hong Kong in 1966 and his Ph.D. in 1971 from the University of California at Irvine in the laboratory of marine invertebrate physiologist, Grover C. Stephens. After a brief postdoctoral fellowship in the laboratory of Wheeler J. North at the Kerckhoff marine laboratory of the California Institute of Technology in Corona del Mar, California, he joined the faculty of the University of San Francisco in 1973. His research has involved the transport of amino acids and metal ions across cell membranes as well as the detoxification mechanisms of metal ions.

## Intelligent design

Chien is a fellow of the Discovery Institute's Center for Science and Culture, hub of the intelligent design movement. Chien is described in the Discovery Institute's Wedge document as leading its "Paleontology Research program", in spite of the fact that, by his own admission, he has no credentials in the field. He has translated several books by intelligent design authors, such as Phillip Johnson's book Darwin on Trial and Jonathan Wells' Icons of Evolution, into Chinese.
